Prevention and Control of Surface Water Hazard in Coal Mine

摘要

On the basis of different damage forms of surface water in coal mines, various prevention and control countermeasures to water hazard in different landforms, such as mountainous area, plain area and hilly area, were proposed. In general, the objects to be governed include river banks, plashes, slopes, gullies and surface collapses due to underground mining or karst cave to avoid the hazard. The principle is cutting off the relationship or passage between surface water and underground mining. Furthermore, advices and techniques on water passage detection were put forward to carry out the following work.
