THE ENVIRONMENTAL GEOLOGICAL PROBLEMS AND CAUSES OF THE SHENFU COALFIELD IN SHAANXI PROVINCE

The Shenfu Coalfield, located in the joint bet between Maowusu desert and Northern Shaanxi loess plateau, is in a fragile geological and ecological and environment. In recent years, excessive mining causes large mined-out area in the coalfield, leading to a series of geo-environmental problems such as ground subsidence, the regional groundwater table declining and mining geological hazards. Based on the data of environmental survey in Shenfu Coalfield, the environmental geological problems of the coalfield are analyzed in the aspects of both natural and artificial factors.
