摘要
王河煤矿位于荥巩矿区中部,为荥巩矿区水害最为严重的矿井之一。为了分析区域地下水流对王河煤矿水害的影响,本文在分析荥巩矿区地质及水文地质条件的基础上,利用GMS建立了荥巩矿区地下水流三维数值模拟模型,确定了水文地质参数和渗流场分布情况。结果表明,荥巩矿区地下水补给量为1831.12×104m3/a,排泄量为4862.88×104m3/a,处于严重的负均衡状态;流入王河煤矿的水量2007年和2008年分别为1058.46和886.87×104m3,与王河煤矿矿井涌水量基本一致。该结果可为王河煤矿矿井水害防治提供依据,为王河煤矿矿井涌水量数值模拟奠定基础。
Wanghe coal mine is located in the middle of Xinggong mining area,and is one of the most serious water hazard mines.In order to analyze the influence of regional groundwater flow on the water hazard of Wanghe coal mine,the groundwater simulation model is constituted using GMS,based on the analysis of the geologic and hydrogeologic conditions of Xinggong mining area,and the hydrogeological parameters and flow field distribution are determined.The results show that the groundwater recharge is 1831.12×104m3/a and groundwater discharge is 4862.88×104m3/a in Xinggong mining area,which is in seriously negative balance situation.The water flows into Wanghe coal mine in 2007 and 2008 are 1058.46 and 886.87×104m3 respectively,which are basically consistent with the mine discharge of Wanghe coal mine.The results can provide a basis for the water hazard prevention and the numerical simulation of mine discharge in Wanghe coal mine.
