摘　　要：为了防治鄂尔多斯地区深埋煤层水害,为其提供重要依据,本文以鄂尔多斯北部泊江海子矿为对象,分析开采水文地质条件和煤层顶板砂岩水及采空积水形成的矿井水害条件;总结工程物探、水文地质钻探、不良钻孔封堵等地面治理技术与治理效果;探讨采空积水防治技术与方法;构建井下地下水动态监测信息保障系统,并提出井下疏放工程优化方法和修订工作面涌水量方法。在生产实践中得到了推广与应用,效果显著。In order to prevent and control the water disaster of deep buried coal seam in Ordos area and provide an important basis for it, this paper takes Bojianghaizi coal mine in northern Ordos as the object to analyze the mining hydrogeological conditions and the mine water disaster conditions formed by sandstone water in coal seam roof and goaf water;summarize the ground treatment technologies and treatment effects such as engineering geophysical exploration, hydrogeological drilling, and bad boreholes plugging;discuss the prevention and control technology and method of goaf water accumulation;build underground water dynamic monitoring information guarantee system, and put forward the optimization method of underground drainage engineering and the method of revising the water inflow of working face. It has been popularized and applied in pro-duction practice with remarkable results.
