MSHA & Mine Safety: What Every Contractor Needs to Know
Mining is one of the most critical industries to modern life but also one of the most dangerous. From coal and copper to precious metals, the materials pulled from the ground power our homes, cars, and economy. Yet for the miners and contractors doing the work, the risks are very real.
That’s why the Mine Safety and Health Administration (MSHA) exists to protect those working in high-hazard mining environments. Whether you're a site contractor, maintenance crew, or equipment operator, understanding MSHA's role—and getting the right training—is non-negotiable.
Here’s what you need to know about MSHA and how to stay compliant while keeping your crew safe.
What Is MSHA and Why Does It Matter?
MSHA was established under the Department of Labor in 1977 to prevent injury, illness, and death in America’s mining operations. Unlike OSHA, which regulates general and construction industry safety, MSHA focuses exclusively on surface and underground mining.
MSHA covers everything from:
Underground coal and metal/nonmetal mining
Surface mining and processing facilities
Contractors performing work on mine property
If your crew is working on mine sites, even temporarily, you must be MSHA compliant.
Key Hazards in Mining Environments
Working in or around mines brings unique risks that require specific controls. MSHA-regulated environments may include hazards like:
Cave-ins and rock falls in underground tunnels
Toxic gas exposure (methane, carbon monoxide, hydrogen sulfide)
Heavy equipment collisions and blind spots
Respirable dust and silica exposure
Explosions and fire risks
Falls from height on surface operations
Even support contractors, electricians, welders, mechanics, face these dangers daily. That’s why hazard recognition and prevention training is a critical part of MSHA compliance.
MSHA Part 46 vs. Part 48: Which One Do You Need?
MSHA regulations are split into two parts:
Part 46 – For surface miners (sand, gravel, limestone, cement, clay, etc.) and their contractors
Part 48 – For underground miners and contractors in coal or metal/nonmetal mining
Not sure which applies to your team? Contact us here and we’ll help you determine the right path.
At Kelly Safety, we offer online MSHA Part 46 training designed for independent contractors, small businesses, and field crews. Get trained fast—and get back to work.
How MSHA Protects Workers: Inspections, Enforcement & Education
MSHA inspectors regularly audit mine sites to ensure safety compliance. These inspections cover everything from:
Ground control and ventilation
Electrical systems
Equipment guarding
Hazard communication
Training records and documentation
Violations can result in immediate fines, citations, or shutdowns. But MSHA doesn’t just enforce—they also educate. Their training initiatives help reduce accidents by empowering crews with life-saving knowledge.
At Kelly Safety, we stay aligned with MSHA’s current guidance to ensure your team is always up to date.
The Role of Technology in Modern Mine Safety
Today’s mining sites are evolving fast. New tools and systems are improving safety in real-time, including:
Proximity detection for heavy equipment
Atmospheric gas monitoring
Autonomous machinery
Virtual reality (VR) hazard training
Dust control and respirable silica detection systems
MSHA continues to collaborate with industry leaders to adopt these innovations—but training still comes first.Technology can’t replace the fundamentals of hazard awareness and response.
Contractors: Stay Ahead of MSHA Requirements
If your team is working on or near a mine, you’re required to have:
A compliant MSHA training plan
Proof of initial and annual refresher training
Task-specific training and site-specific hazard reviews
Emergency response procedures and documentation
Our team at Kelly Safety helps contractors every day with online training, documentation templates, and compliance support. We’ll guide you through it—no guesswork needed.
