Abstract
In order to reduce the coal mine water damage accidents caused by water inrush in the overlying aquifer,the vul-nerability of water inrush in the overlying aquifer of the 3-2# coal seam of Tongsheng Anping Coal Mine was evaluated,and the water richness zoning map was constructed based on the comprehensive analysis of the six types of geoscientific data,in-cluding lithological changes of the overlying aquifer,geological structure,pumping test results,seepage field of the inrush e-vent,geochemistry,and leakage of mud from the drilling holes;and the numerical calculation-obtained height of the water conducting fissure zone above the mining zone was compared with the thickness of the coal seam and the rock layer of the o-verlying aquifer to construct a connectivity map.Based on the vulnerability map and the simulation results,it is considered that the overtopping aquifer is the main measure to prevent and control the water inrush in the overlying aquifer.关键词
