Former coal miners allege that 3M Company’s 8710 respirators, often called dust masks, failed to stop coal dust. They say they developed black lung. 3M denies the claims and says its respirators are effective when used as intended.
The cases are individual suits in Kentucky and West Virginia courts, and no MDL has been formed. In 2019, 3M settled a substantial majority of the then-pending coal dust suits for $340 million.
On September 30, 2026, a federal court let 3M’s racketeering suit against three Kentucky attorneys go forward. 3M alleges the attorneys filed fraudulent claims for former miners.
Latest 3M Dust Mask Lawsuit Updates
September 30, 2026: Judge Lets 3M’s RICO Suit Proceed
Judge Robert Wier of the U.S. District Court for the Eastern District of Kentucky denied motions to dismiss 3M’s racketeering (RICO) suit. The suit names attorneys Glenn Hammond, Michael Martin and Johnny Givens [1]. Discovery can proceed.
He dismissed 3M’s fraud and civil conspiracy claims. 3M alleges the attorneys solicited “cookie-cutter” claims and coached miners to lie. The claims cover about 850 miners in 22 lawsuits.
August 27, 2026: 3M Asks Court for Judicial Notice
Mountain Top Media reported that 3M asked the court to accept results in Adams v. 3M and Mounts v. 3M as fact, called judicial notice [2]. Hammond objected on September 17.
As of September 21, 2026, the court had not ruled. 3M’s motion covers 446 claims. It says 199 were dismissed and 105 faced summary judgment motions. Hammond argues the claims were largely dismissed on procedural grounds.
April 3, 2026: Kentucky Appeals Court Affirms Wilson Ruling
Kentucky’s appeals court affirmed the denial of coal miner Johnny Wilson’s motion for relief. It dismissed 3M’s cross-appeal as moot. The opinion is unpublished.
The Pike Circuit Court had dismissed Wilson’s suit as time-barred on March 9, 2023. It found attorney Hammond’s affidavit “materially false.”
November 14, 2025: West Virginia Court Upholds Time-Bar Rulings
Insurance Journal reported that the Supreme Court of West Virginia upheld findings that coal miners’ respirator suits against 3M and other makers and suppliers were filed too late [3].
The court found the miners knew or should have known of their injuries, in one case as far back as 1998. It found no fraudulent concealment.
April 25, 2018: Kentucky Jury Awards Miners $67.5 Million
A Knott County, Kentucky jury awarded $67.5 million to coal miner brothers Leslie and Michael Cox against 3M, the Lexington Herald-Leader reported [4]. The verdict came in a case over 3M’s 8710 respirator.
What Are 3M Dust Masks?
According to 3M’s SEC filing, the lawsuits allege use of some of its mask and respirator products. They seek damages for alleged injury from workplace exposure to asbestos, silica, coal mine dust or other dusts [5].
The coal dust cases center on 3M’s 8710 respirator. Kentucky’s appeals court calls it a disposable, single-use mask that miners called a dust mask.
Who May Be Affected?
Coal miners who wore 3M 8710 disposable respirators on the job and were later diagnosed with black lung, also called pneumoconiosis, bring these suits.
Their families may bring them too. Wilson sued 3M in Pike Circuit Court in March 2020, and 52 other coal miners joined his case. A legal review of your own work and diagnosis dates decides if a claim fits.
Reported Injuries or Damages
The coal miners in these cases allege that they developed black lung. The court record uses the term pneumoconiosis, commonly known as black lung.
The Herald-Leader reported that breathing in coal dust causes black lung. It called black lung an incurable disease that chokes off breathing and often leads to early death.
In the Wilson case, the miner claimed 3M was negligent and strictly liable for design defects in the respirator. He also claimed breach of implied warranty and fraud. These are allegations, and 3M disputes them.
Evidence to Preserve
Keep any records that show your work, your mask and your diagnosis. Useful items are:
- Pay stubs, employment records and work-history records that show your mining jobs and dates.
- Records of which mask or respirator was issued or bought, including the box, packaging or receipts.
- Medical records and the date of any black lung diagnosis, since that date can decide a case.
- Black lung benefits files and workers’ compensation files kept by you or your family.
- Letters and messages with any attorney or company about your illness or your claim.
- A written timeline of when you first learned your illness might be linked to a respirator.
Filing Deadlines
Filing deadlines come from state law, so they depend on where you live and on when a doctor diagnosed your illness.
Courts in Kentucky and West Virginia have thrown out miners’ respirator claims on timing alone. Missing the deadline can end a miner’s claim, whatever the facts.
Talk to a lawyer promptly, because the date you first knew a mask might be involved can matter to your claim.
Potential Compensation
If a claim succeeds, damages can include medical bills and lost income. They can also include pain and suffering and, in some cases, punitive damages. A spouse may claim loss of consortium.
The named public results are the 2018 Cox verdict and the 2019 settlement. The settlement covered most then-pending suits in both states, including the Cox verdict. The appeal of the Cox verdict was dismissed.
Compensation amounts vary by case. Past results do not guarantee future outcomes. Potential compensation depends on the facts of each claim.
Frequently Asked Questions
How Much Will Each Person Get from the 3M Dust Mask Lawsuit?
No per-person amount has been published for the 3M dust mask lawsuit. 3M’s SEC filing gives only the total. In the 2018 Cox case, the jury awarded the two brothers $3.75 million and $1.25 million in compensatory damages.
Did a Jury Find 3M’s Dust Masks Defective?
A Knott County jury did find 3M’s 8710 respirator in a defective and unreasonably dangerous condition in 2018. It found 3M acted with reckless disregard. It assigned 3M 40 percent and 30 percent of the fault for the brothers’ lung injuries because both smoked.
How Long Do Coal Miners Have to File a 3M Dust Mask Lawsuit?
Coal miners’ deadline to file a 3M dust mask lawsuit depends on the state. Kentucky’s one-year limit, KRS 413.140(1)(a), ran from when Wilson knew of the alleged link by January 2019. West Virginia has a two-year limit on injury suits.
Did the Sixth Circuit Keep Two 3M Respirator Cases in Federal Court?
In April 2023, the Sixth Circuit reversed a district court order that had sent two cases with over 400 plaintiffs back to state court. Those cases will remain in federal court, according to 3M’s filing.
