摘　　要：为了防止矿井水对煤矿开采的影响,研究了章村矿开采受水害影响程度,开采受水害影响的含水层包括山西组2号煤顶板砂岩含水层,煤层底板下野青灰岩含水层矿井偶有突水,对局部的采掘工程有影响;根据《煤矿防治水细则》中矿井水文地质分类的6项指标,对应章村矿开采的实际地质及水文地质条件,确定章村矿水文地质类型符合矿井水文地质类型标准的复杂类型条件。根据章村矿主要面临顶板砂岩水工作面开采后形成的老空水的防治问题,提出了防治水建议。研究为周边矿井水害治理提供了借鉴。In order to prevent the influence of mine water on coal mining,this paper studies the degree of water damage in Zhangcun Mine.The aquifers affected by water damage include the No.2 coal roof sandstone aquifer in Shanxi Formation,and the occasional water inrush in the field limestone aquifer under the coal seam floor,which has an impact on local mining projects;according to the six indicators of mine hydrogeological classification in the"Detailed Rules for Water Prevention and Control in Coal Mine",corresponding to the actual geological and hydrogeological conditions of Zhangcun Mine mining,it is determined that the hydrogeological type of Zhangcun Mine is in line with the mine complex type conditions for hydrogeological type criteria.Based on the prevention and control of the old goaf water formed after the mining of the roof sandstone water working face in Zhangcun Mine,suggestions for prevention and control of water are put forward.The research provides a reference for the management of water hazards in surrounding mines.
