Underground mines
- Roof collapse (cave-in): rocks or the tunnel roof can fall, crushing or trapping miners. Miners use supports (beams, bolts) and follow roof-control plans to stay safe.
- Bad air (toxic gas or low oxygen): gases like methane or carbon monoxide, or not enough oxygen, can make people sick or cause explosions. Mines use ventilation systems and gas monitors to detect and remove dangerous air.
Surface mines
- Heavy equipment accidents: large trucks and shovels can hit workers or flip over because they are big and hard to stop. Workers wear high-visibility clothing, follow traffic rules, and use spotters to prevent crashes.
- Highwall or slope collapse: the sides of open pits can collapse, causing rockfalls or landslides that can bury people or machines. Engineers design safe slope angles and keep people away from unstable edges.
