Safety Diploma Course

MSHA Underground Mining Confined Spaces


This course is designed to help you achieve a general awareness of the health and safety hazards that exist in confined spaces at underground mine sites. The course highlights various hazards found in confined spaces at underground mine sites and provides best practices for accident prevention during operations in such spaces.

Governing regulations

To help American mines operate safely, congress enacted the Federal Mine Safety and Health Act of 1977 (Mine Act) and the Mine Improvement and New Emergency Response Act (“MINER Act”). The Mine Safety and Health Administration (MSHA), part of the US Department of Labor, was established in 1978 to regulate the mining industry and enforce these acts.

Every person at a mine site has a responsibility to ensure that health and safety standards are observed at all times. The employer is responsible for providing information, instruction, and supervision to all workers. The supervisor is responsible for ensuring that all workers are properly trained and are compliant with MSHA and OSHA regulations. And workers are responsible for observing all MSHA and OSHA standards and practicing safe work habits.

To be MSHA compliant your company must have a training plan that is approved by MSHA and administered by a competent person. Your company can use this or any of our courses as part of that plan.

If you are unsure how to write a training plan we can help with our Part 48 Underground Mining Training Plan course, the only one like it in the mining industry.
