Publicity given to the detrimental effects of mining activities on the environment has tended to overshadow somewhat the hydrologic opportunities and benfits that could be associated with these activities. For example, many areas disturbed by surface mining have proved to be excellent recharge areas for groundwater aquifers. The degree to which mine sites can be exploited to improve management ...

According to the development requirements of green mining of coal resources, it is imperative to improve the extraction rate of coal and the application of safe and efficient mining technology. Pre-splitting and roof cutting technology is widely used in reducing residual coal pillars and safe pressure relief mining, which has become the crucial technology for pillar-free mining methods ...

In one process, called strip mining, miners take coal from just below the surface. In deep mining, miners dig long tunnels to get to coal that is buried far underground. Mining coal can be dangerous for the miners. Coal miners can be injured or killed when mine roofs collapse. Gases trapped in coal sometimes cause fires or explosions.
