Abstract:Yuli coal mine and Yancun coal mine is the mining information blind area, The electromagnetic and the seismic method is not suitable for exploration goaf, due to the Wangzhuang coal mine, Zhangze Power Plant, high voltage corridor, Changzhi-Handan highway. As a result of mining rock density difference, microgravity is suitable for exploration goaf. The field verification, drilling and mining rock movement deformation analysis, and exploration results consistent. Gravity anomaly zone in goaf evenly sink area exists in the rock mass deformation. With this method, the mining boundary are explored, offering convenient and effective exploration means for exploration goaf.
