You fill out DOL Form AB-1 by entering the miner’s personal data, every coal mine job in chronological order, the dates worked, the employer’s full legal name and address, the type of work performed, and the daily duties that exposed the miner to coal dust, then signing and dating the form under penalty of perjury before sending it to the U.S. Department of Labor’s Division of Coal Mine Workers’ Compensation. The form is the centerpiece of a federal Black Lung benefits claim under the Black Lung Benefits Act, 30 U.S.C. §§ 901–945, and it tells the District Director who the responsible operator is and whether the miner qualifies for the powerful 15-year presumption under 30 U.S.C. § 921(c)(4).
A wrong, blank, or padded AB-1 can sink an otherwise winnable claim. The governing rule at 20 C.F.R. § 725.202 defines who counts as a “miner,” and 20 C.F.R. § 725.493 tells the agency how to use your AB-1 answers to identify the last coal mine employer that owes benefits.
According to the DOL FY 2024 DCMWC statistics, more than 25,700 miners and survivors received monthly federal black lung payments, and the basic monthly rate for a single beneficiary in 2026 sits at roughly $828.30 under the 50% of GS-2, Step 1 formula in 30 U.S.C. § 922.

What DOL Form AB-1 Actually Is
Form AB-1, titled Employment History, is one of the four core intake forms in the federal black lung claim packet issued by the Office of Workers’ Compensation Programs (OWCP). It works alongside Form CM-911 (Claim for Benefits), Form CM-911a (Description of Coal Mine Work), and the medical authorization Form CM-936. The AB-1 is the document the District Director relies on most heavily when applying 20 C.F.R. § 725.494 to name the potentially liable operator.
In plain English, AB-1 is the miner’s sworn work history, and it answers three legal questions at once. It proves the claimant is a “miner” under 30 U.S.C. § 902(d), it counts the years of qualifying coal mine employment, and it points the agency at the company that must pay if the claim is awarded. The consequence of a sloppy AB-1 is severe, because the Benefits Review Board routinely affirms denials when the work history fails to support 15 years of qualifying employment.
A real-world example shows the stakes. In Big Branch Resources, Inc. v. Ogle, 737 F.3d 1063 (6th Cir. 2013), the court used the miner’s AB-1-style work history to uphold the 15-year presumption against the operator. A common misconception is that AB-1 is “just paperwork” the lawyer fills out later, but the DCMWC Procedure Manual treats it as sworn evidence from the moment the claimant signs it.
Who Must File Form AB-1
Any living coal miner filing a claim under Part C of the Black Lung Benefits Act must submit AB-1, and so must a surviving spouse, child, parent, brother, or sister filing a survivor’s claim under 20 C.F.R. § 725.212. The form must reflect the deceased miner’s history when a survivor files, because survivor benefits depend on whether the miner had pneumoconiosis arising from coal mine employment.
The consequence of skipping AB-1 is automatic, because 20 C.F.R. § 725.405 lets the District Director treat an incomplete claim as abandoned after one year of inaction. Imagine Hazel, a 71-year-old widow in Pikeville, Kentucky, who files CM-911 but skips AB-1 because she cannot remember every mine; the District Director will issue a development letter, and the one-year clock starts ticking the day she ignores it.
A common misconception is that the employer fills out AB-1, but the miner or survivor is the one who signs and certifies it. The employer instead receives Form CM-2970a (Operator Response) once the District Director uses the AB-1 to name it as the responsible operator.
Where AB-1 Fits in the Claim Packet
The DOL CM-911 claim packet includes the claim form, AB-1, the medical release, and the description of coal mine work. Each form has a different evidentiary purpose, and missing one stalls the claim at the District Director stage governed by 20 C.F.R. § 725.401.
The consequence of filing AB-1 alone, without CM-911, is that no claim exists, because 20 C.F.R. § 725.301 requires a written claim signed by the claimant. Picture Earl, a 64-year-old retired miner in Beckley, West Virginia, who mails AB-1 by itself; DCMWC will return it with a cover letter telling him to file CM-911 first.
A common misconception is that AB-1 is the claim itself. It is not, but it is the evidentiary backbone the rest of the claim leans on.
Why the Form Matters Legally
The AB-1 drives three statutory machines: the responsible operator designation, the 15-year presumption, and the length-of-employment count that controls whether complicated pneumoconiosis triggers the irrebuttable presumption under 30 U.S.C. § 921(c)(3). Each machine runs on the dates, employers, and duties the miner writes on AB-1.
The plain-English explanation is that the more accurately the miner documents underground or surface dust exposure, the more presumptions tilt in the claimant’s favor under 20 C.F.R. § 718.305. The consequence of a thin AB-1 is the loss of those presumptions, which forces the miner to prove total disability and disease causation from scratch under the tougher standards in 20 C.F.R. § 718.204.
A real-world scenario: Marcus, a 58-year-old surface miner in Gillette, Wyoming, lists only “truck driver” without explaining the haul roads were inside the active mine pit. The District Director may not credit those years as “coal mine employment” because 20 C.F.R. § 725.202(a) requires work in or around a coal mine. A common misconception is that surface miners cannot get black lung benefits, but the Supreme Court’s decision in Usery v. Turner Elkhorn Mining Co., 428 U.S. 1 (1976), confirmed coverage for both surface and underground miners.
The 15-Year Presumption
Under 30 U.S.C. § 921(c)(4) and 20 C.F.R. § 718.305, a miner with 15 or more years of qualifying coal mine employment who proves a totally disabling respiratory or pulmonary impairment is presumed to have pneumoconiosis caused by that employment. The operator must then rebut by showing the miner does not have pneumoconiosis or that the disease did not arise out of coal mine work.
The consequence of falling short of 15 years on AB-1 is the loss of this presumption, and the claim then turns on element-by-element proof. Roy, a 67-year-old miner in Norton, Virginia, who lists 14 years and 9 months on AB-1 may lose the presumption, even though rounding rules in the DCMWC PM Chapter 2-700 sometimes credit fractional years.
A common misconception is that any coal-related job counts. Office work at corporate headquarters does not count under 20 C.F.R. § 725.202.
The Responsible Operator Rule
20 C.F.R. § 725.495 directs the District Director to name the most recent coal mine operator that employed the miner for at least one cumulative year and that remains capable of paying benefits. Your AB-1 entries determine which company gets that bill.
The consequence of listing the wrong “last employer” can be catastrophic, because if the named operator goes out of business or proves it employed the miner for less than a year, liability shifts to the Black Lung Disability Trust Fund. Picture Earl again: he lists a defunct contractor as his last employer when he actually finished his career at a still-operating mine; the operator escapes liability, and the Trust Fund pays.
A common misconception is that the first mine matters most. Under 20 C.F.R. § 725.494, the most recent qualifying operator is generally the one on the hook.
Step-by-Step: How to Fill Out Form AB-1
Form AB-1 is short, but every line carries weight. The DOL prints the current edition with an OMB control number that you can verify on reginfo.gov. The form has five blocks, and you should complete each in ink or in a fillable PDF saved as a flattened file.
The general rule is to write in chronological order from the first coal mine job to the most recent, never to skip jobs you “only worked a few months,” and never to merge two employers into one row. The consequence of merging is that the District Director may discount the entire row under 20 C.F.R. § 725.456, which governs the admissibility of evidence.
Picture Loretta, a 69-year-old widow in Madisonville, Kentucky, completing AB-1 for her late husband’s claim. She has his Social Security earnings statement, two W-2 boxes from the attic, and a union pension letter; she should use all three to reconstruct dates. A common misconception is that “approximate” dates are fine, but the District Director prefers month-and-year precision because it controls the one-year cumulative employment threshold.
Block 1: Miner’s Identifying Information
Enter the miner’s full legal name, Social Security number, date of birth, and current mailing address. If the miner is deceased, enter the date of death and write “Deceased” next to the name, because the survivor claim under 20 C.F.R. § 725.201 requires it.
The consequence of an incorrect SSN is a delayed claim, because DCMWC cross-checks the Social Security Administration earnings record to verify employment dates. Hazel should write her late husband’s SSN exactly as it appears on his Social Security card, not from memory.
A common misconception is that nicknames are acceptable. They are not, because mine payroll systems used legal names.
Block 2: Employer Name and Address
For each job, write the full legal name of the company, not the mine’s nickname. “Mine #7” is wrong; “Consolidation Coal Company, Mine #7, Mannington, WV” is right. Include the street address or, if unknown, the town and state.
The consequence of vague employer names is that DCMWC cannot serve notice on the operator, which delays the claim under 20 C.F.R. § 725.407. Earl should pull his W-2s or call the West Virginia Office of Miners’ Health, Safety and Training for help reconstructing employer names.
A common misconception is that successor companies are interchangeable. They are not; 20 C.F.R. § 725.492 treats corporate successors specifically.
Block 3: Dates of Employment
Use month-year format, such as “06/1978 to 09/1992.” Do not write “1978–1992” alone, and do not leave the end date blank for jobs that have ended.
The consequence of vague dates is that the District Director may pick the shorter possible interval when applying 20 C.F.R. § 725.493(b) to compute years of coal mine employment. Marcus should use his SSA earnings record to pin down quarter-by-quarter employment.
A common misconception is that a year with any coal mine work counts as a full year. The agency typically uses 125 working days as a year under 20 C.F.R. § 725.101(a)(32).
Block 4: Job Title and Daily Duties
Write the official job title (for example, “continuous miner operator,” “roof bolter,” “shuttle car operator,” “haul truck driver,” “tipple worker,” or “preparation plant attendant”) and a one-sentence description of the daily exposure to coal or rock dust. The duties description triggers or defeats the 20 C.F.R. § 718.204(b)(1) “usual coal mine work” test for total disability.
The consequence of a generic entry like “miner” is that the agency cannot tell whether the work was qualifying under 20 C.F.R. § 725.202(d)(2). Roy should write “underground continuous miner operator; cut coal at the face for 8–10 hours per shift; constant exposure to respirable coal mine dust.”
A common misconception is that “supervisor” jobs do not count. They count if the supervisor regularly entered dust-exposed areas, per the Director, OWCP v. Consolidation Coal line of cases.
Block 5: Certification and Signature
Sign and date the form. The signature is sworn under 18 U.S.C. § 1001, which makes a knowingly false statement a federal crime punishable by up to five years in prison.
The consequence of an unsigned AB-1 is rejection, because DCMWC cannot accept unsworn employment evidence. Loretta should sign as “Spouse of [Miner]” and attach a copy of her husband’s death certificate.
A common misconception is that an electronic signature is invalid. The E-SIGN Act, 15 U.S.C. § 7001, and DOL practice both accept e-signatures on AB-1.
Three Realistic Scenarios
Below are three of the most common AB-1 patterns, each in a 2-column table that maps the miner’s Entry Choice to the Legal Effect under the regulations.
Scenario A: Underground Miner With 28 Years at One Mine
| Entry Choice | Legal Effect |
|---|---|
| Lists single employer, full month-year dates, “roof bolter” title | Triggers 15-year presumption under 20 C.F.R. § 718.305 |
| Names current operating company as last employer | Operator designated under 20 C.F.R. § 725.495 |
| Describes daily face-work dust exposure | Supports “usual coal mine work” total-disability standard under 20 C.F.R. § 718.204 |
Scenario B: Surface Miner Who Drove Haul Trucks 17 Years
| Entry Choice | Legal Effect |
|---|---|
| Lists each contractor separately, even short stints | Allows accurate cumulative-year count under 20 C.F.R. § 725.493 |
| Specifies “haul truck operator inside active pit, exposed to silica and coal dust” | Confirms qualifying work under 20 C.F.R. § 725.202 |
| Notes pit conditions, road dust, and shift hours | Strengthens evidence under the substantially similar conditions test |
Scenario C: Surviving Spouse Filing for Late Husband
| Entry Choice | Legal Effect |
|---|---|
| Reconstructs work history with SSA Form SSA-7050 earnings record | Meets evidentiary standard at 20 C.F.R. § 725.456 |
| Lists every employer chronologically, even small contractors | Identifies last responsible operator under 20 C.F.R. § 725.495 |
| Signs as surviving spouse, attaches death certificate | Establishes survivor standing under 20 C.F.R. § 725.212 |
Three Named Examples
Earl Caudill, age 64, worked 31 years underground at three Boone County, West Virginia, mines. He filled AB-1 with month-year dates from 1985 to 2016, listed each employer’s full legal name, and described daily roof-bolting near the face. The District Director credited 31 years, applied the 15-year presumption, and named the current operator as the responsible operator.
Marcus Reyes, age 58, drove haul trucks for 17 years at a Powder River Basin surface mine in Wyoming. He carefully wrote “haul truck operator inside the active pit; constant exposure to coal and overburden dust on haul roads,” which preserved his eligibility despite the common misconception that surface miners are not covered.
Loretta Hensley, age 69, filed a survivor’s claim after her husband Hobart died of complicated pneumoconiosis in Madisonville, Kentucky. She used his SSA earnings record under 20 C.F.R. § 725.456 to fill AB-1, attached the death certificate, and listed all four operators in chronological order, which let DCMWC apply the irrebuttable presumption under 30 U.S.C. § 921(c)(3).
Mistakes to Avoid
- Skipping short jobs. Leaving off a 6-month contractor stint can cost you the responsible operator under 20 C.F.R. § 725.495.
- Vague employer names. “ABC Mine” gives the District Director nothing to work with under 20 C.F.R. § 725.407.
- Year-only dates. “1980–1995” forces unfavorable rounding under 20 C.F.R. § 725.493.
- Generic job titles. “Miner” loses the qualifying-work analysis under 20 C.F.R. § 725.202.
- Forgetting to sign. An unsigned AB-1 cannot be considered evidence under 18 U.S.C. § 1001.
- Listing office or corporate jobs as mine work. Non-mine work is excluded by 20 C.F.R. § 725.202(a).
- Failing to attach the death certificate in a survivor claim, which delays the case under 20 C.F.R. § 725.212.
- Padding years to reach 15 — perjury exposure under 18 U.S.C. § 1001.
- Naming a defunct operator as last employer when a viable successor exists under 20 C.F.R. § 725.492.
- Ignoring SSA earnings records, which are the single best corroborating evidence under 20 C.F.R. § 725.456.
Federal vs. State Black Lung Programs
The federal Black Lung Benefits Act, administered by DCMWC, is the primary path. Several major coal states run separate state programs that may pay additional benefits, and they sometimes use their own work-history forms in parallel.
The consequence of relying only on a state form is that you have not preserved your federal claim, because federal benefits require the federal CM-911 and AB-1 packet under 20 C.F.R. § 725.301. Picture Earl filing only with the West Virginia Workers’ Compensation OOL Board — he might still be inside the federal three-year statute at 20 C.F.R. § 725.308, but if he waits, he loses federal rights.
A common misconception is that the state program offsets dollar-for-dollar against the federal one. Coordination rules at 30 U.S.C. § 932(g) are more nuanced than that.
Kentucky
Kentucky’s Workers’ Compensation Board administers a state black lung component under KRS Chapter 342, and Kentucky still requires CT-scan-confirmed Category A or higher findings for top-tier benefits. The consequence of a thin AB-1 is the same in Kentucky: you cannot prove qualifying employment under the Kentucky black lung statute. Hazel should file in both forums to preserve every dollar.
West Virginia
The West Virginia Office of the Insurance Commissioner and the Occupational Pneumoconiosis Board handle state OP claims under W. Va. Code § 23-4-1. The consequence of skipping the state filing is the loss of state-only awards. Earl should file the West Virginia claim within three years of last exposure.
Pennsylvania
Pennsylvania’s Bureau of Workers’ Compensation handles occupational disease claims under the Pennsylvania Workers’ Compensation Act. A miner who worked anthracite operations near Hazleton must file within 300 weeks of last exposure, a much shorter deadline than federal law.
Virginia
The Virginia Workers’ Compensation Commission administers Va. Code § 65.2-500 occupational disease claims, including coal worker pneumoconiosis. Roy in Norton, Virginia, must file his state claim within five years of last injurious exposure or two years of diagnosis, whichever is later.
Do’s and Don’ts
- Do request your SSA Form SSA-7050 earnings record before drafting AB-1, because it gives quarter-by-quarter dates that survive cross-examination.
- Do write each employer’s full legal name and mine ID, because MSHA’s Mine Data Retrieval System lets the District Director verify employers in seconds.
- Do describe your daily duties in dust-exposure language, because the 15-year presumption depends on the agency seeing qualifying work.
- Do sign and date the form in ink, because 18 U.S.C. § 1001 requires sworn certification.
-
Do attach corroborating documents like W-2s, pension statements, and union cards, because 20 C.F.R. § 725.414 limits what you can add later.
-
Don’t guess at dates, because rounding hurts you under 20 C.F.R. § 725.493.
- Don’t lump multiple employers into one row, because the District Director cannot serve 20 C.F.R. § 725.407 notices.
- Don’t omit short or seasonal jobs, because they may push you over the 15-year threshold.
- Don’t include non-mine jobs to inflate years, because perjury under 18 U.S.C. § 1001 is a felony.
- Don’t skip the duties description, because Director, OWCP v. Greenwich Collieries, 512 U.S. 267 (1994), put the burden of persuasion on the claimant.
Pros and Cons of Self-Filing AB-1
- Pro: No legal fees, since the DOL claim packet is free.
- Pro: You know your own work history better than anyone, especially small contractors.
- Pro: DCMWC district offices help claimants complete the form for free.
- Pro: Faster filing protects your spot under the three-year statute at 20 C.F.R. § 725.308.
-
Pro: You preserve attorney-client choice for the contested phase.
-
Con: Self-filers often miss the responsible operator nuance under 20 C.F.R. § 725.495.
- Con: No one cross-checks your dates against MSHA records.
- Con: Self-filers sometimes write generic job titles that defeat the 15-year presumption.
- Con: Operators get free attorneys; you do not.
- Con: Attorney fees are paid by the operator if you win, so the upfront-cost worry is overstated.
Court Rulings That Shape AB-1 Practice
The Supreme Court in Usery v. Turner Elkhorn Mining Co., 428 U.S. 1 (1976), upheld the constitutionality of the Black Lung Benefits Act and confirmed coverage for surface and underground miners alike. The Court in Mullins Coal Co. v. Director, OWCP, 484 U.S. 135 (1987), narrowed the old interim presumption, which is why today’s claimants depend so heavily on the 15-year presumption.
The Sixth Circuit in Big Branch Resources v. Ogle, 737 F.3d 1063 (2013), used the miner’s AB-1-style work history to invoke the 15-year presumption against the operator. The Fourth Circuit in Westmoreland Coal Co. v. Cochran, 718 F.3d 319 (2013), reinforced that substantially similar conditions — surface mining included — count toward the 15-year clock.
Director, OWCP v. Greenwich Collieries, 512 U.S. 267 (1994), placed the ultimate burden of persuasion on the claimant, which is precisely why a meticulous AB-1 matters.
Where and How to File
Mail or e-file the completed CM-911 packet, including AB-1, to the DCMWC District Office closest to the miner’s residence. The agency offers a secure upload portal for digital filings, and you can also visit a district office in person.
The consequence of filing in the wrong office is a delay, but not a denial, because 20 C.F.R. § 725.404 lets DCMWC transfer the file. Marcus in Wyoming should mail his packet to the Denver district office.
A common misconception is that you must use a lawyer to file. You do not, and the Black Lung Clinics Program at HRSA provides free help.
FAQs
Is Form AB-1 mandatory in every black lung claim?
Yes. Every claim under 20 C.F.R. § 725.301 must include an employment history, and AB-1 is the DOL form that captures it.
Can a surviving spouse file AB-1 on behalf of a deceased miner?
Yes. A spouse, child, parent, or sibling filing under 20 C.F.R. § 725.212 reconstructs the miner’s work history using SSA earnings, W-2s, and pension records.
Does surface mining count toward the 15-year presumption?
Yes. 20 C.F.R. § 718.305 credits surface coal mine employment when conditions were substantially similar to underground exposure.
Do I need 15 years of coal mine work to win?
No. Miners with fewer than 15 years can still win by proving each element of entitlement under 20 C.F.R. § 718.202.
Can I file AB-1 online?
Yes. DCMWC accepts e-filed packets through its secure portal, and e-signatures are valid under 15 U.S.C. § 7001.
Is there a statute of limitations on filing?
Yes. 20 C.F.R. § 725.308 sets a three-year window from a qualifying medical determination, and survivors generally have a parallel deadline.
Will my employer see my AB-1?
Yes. The named responsible operator receives the AB-1 with a notice of claim under 20 C.F.R. § 725.407.
Can lying on AB-1 lead to criminal charges?
Yes. Knowingly false statements violate 18 U.S.C. § 1001 and carry up to five years in federal prison.
Do I have to list jobs that lasted only a few weeks?
Yes. Short stints still count toward cumulative employment under 20 C.F.R. § 725.493 and may shift the responsible operator.
Will the Trust Fund pay if my last employer is bankrupt?
Yes. The Black Lung Disability Trust Fund pays when no operator is financially capable, under 26 U.S.C. § 9501.
Are attorney fees covered if I win?
Yes. Under 30 U.S.C. § 932(a), the responsible operator pays reasonable attorney fees on a successful claim, so claimants pay nothing out of pocket.
Can I amend AB-1 after filing?
Yes. You can supplement the work history at the District Director stage under 20 C.F.R. § 725.414, but later amendments face evidentiary limits.
