hazards associated with hard rock mining:

Environmental Risks of Mining

Environmental hazards are present during every step of the open-pit mining process. Hardrock mining exposes rock that has lain unexposed for geological eras. When crushed, these rocks expose radioactive elements, asbestos-like minerals, and metallic dust. During separation, residual rock slurries, which are mixtures of pulverized rock and liquid, are produced as tailings, toxic and radioactive elements from

→ Cave-ins, collapses, or rock falls: The infrastructure of mines can sometimes result in catastrophe. The roof of a mine can collapse and cause rocks and debris to become unstable and possibly strike workers. Sometimes collapses are scheduled and systematically planned and control the hazard of a cave in. Appropriate safety plans will need to be practiced and workers should be trained on what to
