Abstract
According to the basic characteristics of geological environment in Pingyao mining area, we analyzed the relationship between coal mining and the ground fissure disasters in recent years. The result shows that the mine goaf is the essential factor for the formation of ground fissure, and the precipitation and groundwater drainage accelerates its development. Based on a systematic analysis of classification of goaf as well as the distribution characteristics and the formation mechanism of ground fissure, we found that the ground fissure in this area is non-tectonic, and thus proposed corresponding prevention and control measures. Research results would provide basis for the improvement of local environmental conditions and the control of geological disasters.
