DOL/MSHA RIN: 1219-AB75 Publication ID: Fall 2011
Title: Examination of Work Areas in Underground Coal Mines for Violations of Mandatory Health or Safety Standards
Abstract: In the ever changing mine environment, it is critical that hazardous conditions be recognized and abated quickly. Additionally, other conditions that could develop into a hazard if left uncorrected must also be eliminated. Operator examinations for hazards and violations of mandatory health or safety standards are mandated in the Mine Act and are a critical component of an effective safety and health program for underground mines. While this requirement was previously included in regulations, the 1992 final rule addressing ventilation in underground coal mines only included the requirement that the mine examiners look for hazardous conditions. The 1992 rule omitted from the standard the text taken from the Mine Act requiring examinations for violations of mandatory health or safety standards during preshift examinations. The final rule will revise existing standards for preshift, supplemental, on-shift, and weekly examinations to address violations of mandatory health or safety standards.

Statement of Need: Underground coal mines usually present harsh and hostile working environments, and the ventilation system is the most vital life support system in underground mining. A properly operating ventilation system is essential for maintaining a safe and healthful working environment. Examinations of work areas that include the ventilation system are the first line of defense for miners working in underground coal mines and are necessary to protect miners. Conditions in underground coal mines change rapidly--roof that appears adequately supported can quickly deteriorate and fall; stoppings can crush out and short-circuit air currents; conveyor belts can become misaligned or belt roller bearings can fail, resulting in an ignition source; and methane can accumulate in areas where it may not have been detected. Diligent compliance with safety and health standards and safety-conscious work practices provide a substantial measure of protection against mine accidents and emergencies. To assure optimum safety of miners, it is imperative that operators find violations of health or safety standards, correct them, and record corrective actions taken.

Summary of the Legal Basis: Promulgation of this regulation is authorized by sections 101 and 303 (d)(1) and (f) of the Federal Mine Safety and Health Act of 1977.

Alternatives: The proposal included several alternatives in the preamble and requested comments on them.

Anticipated Costs and Benefits: MSHA estimated that the proposed rule would cost $15.3 million yearly and result in net benefits of $6.0 million yearly.

Risks: Failure to conduct adequate examinations to identify, report, and correct hazardous conditions and violations of health and safety standards has resulted in serious accidents and fatalities. Lack of adequate ventilation in underground mines has resulted in fatalities from asphyxiation and explosions.
