The resurgence of these problems invited various Governmental and legislative reforms in occupational safety. The coal mining worldwide has posed problems of health and accidents. Roof collapse and flooding has caused many deaths. Efforts by technology, legislation and enforcement are continuously made to create mining operation safe.
