Coal mining, the first step in the dirty lifecycle of coal, causes deforestation and releases toxic amounts of minerals and heavy metals into the soil and water. The effects of mining coal persists for years after coal is removed. Dear Readers, ...
For this reason, coal mining worldwide is heavily regulated through health and safety laws. Through the development of new equipment for personnel protection, new approaches to mine design, more effective emergency preparedness plans and procedures, and major changes in legislation, regulation, and enforcement, higher standards of health and ...
Underground mining, sometimes called deep mining, is a process that retrieves coal from deep below the Earth’s surface—sometimes as far as 300 meters (1,000 feet).
