摘要： 主要对小常煤矿河下开采安全性进行了分析研究，首先通过区域勘探，探清该区域含水层、表土层厚度、煤层及构造情况|采用理论计算和打钻实测方法，确定导水裂隙带高度|通过含水层和隔水层分析、大气降水与矿井涌水量历年统计，最终确定河水对井下开采的影响，对矿井进行河下开采具有重要指导意义。同时利用地表下沉软件，对开采后地表下沉情况进行了模拟，为矿井开展地面河道治理提供指导。
关键词: 水下开采, 综采放顶煤开采, 导水裂隙带, 含水层
Abstract: This paper mainly analyzes and studies the safety of mining under river, First of all, through regional exploration, the water abundance, surface soil thickness, coal seam and structure are explored; Based on theoretical calculation and drilling measurement, the height of water flowing fractured zone is determined; through the analysis of aquifer and impermeable layer, the amount of precipitation and the amount of water inflow in the mine, the influence of river water on underground mining is finally determined,It has important guiding significance for mine under River Mining. At the same time, the ground subsidence is simulated by using the surface subsidence software, Providing guidance for the mine of the ground river course.
