    What are risks associated with mining? Creative

    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 do in case of a cave in or a collapse in the mine.
