The Trump administration has indefinitely suspended enforcement of federal regulations limiting coal miners' exposure to silica dust particles, sparking protests from worker advocacy groups concerned about escalating black lung disease rates. The postponement affects Mine Safety and Health Administration rules that would have established stricter exposure limits for carcinogenic particles in mining operations.

Industry organizations have challenged the regulations through federal lawsuits, arguing that compliance would be economically unfeasible and that personal protective equipment provides adequate worker protection. The National Stone, Sand & Gravel Association and other trade groups contend that the new standards would impose unrealistic operational constraints on mining companies across the sector.

Black lung disease now affects approximately 20% of long-tenured coal miners in central Appalachia, representing a significant increase since the 1990s when newer extraction techniques began generating higher concentrations of harmful dust particles. The United Mine Workers of America warns that each day without proper enforcement represents additional health risks for active miners and potential workforce shortages as younger workers develop respiratory complications.

The regulatory uncertainty occurs against a backdrop of continued coal industry contraction, with production declining to 578 million short tons in 2023, less than half the 2008 peak levels. Despite federal initiatives to designate additional mining acreage and modernize coal-fired generation facilities, the sector faces ongoing challenges from competing energy sources and evolving environmental policies.
