摘　　要：针对浅埋深地形河沟下工作面存在的涌突水风险问题,以山西华鹿阳坡泉煤矿典型工作面为例,在系统分析工作面水文地质条件、导水通道及水源强度后得出,大气降水及地表水是工作面主要充水水源,受工作面开采后导水裂缝带的沟通,存在涌突水风险。通过对水源强度的计算以及工作面排水能力的评估,工作面及外围的排水能力大于河沟水、降水直接倒灌时预计的出水量,满足工作面排水要求。通过对强降雨水、南石沟水、采空区水采取多方位管控措施,并配合排水系统管控,确保了浅埋深地形河沟下工作面的回采安全,并得到工作面回采验证。分析过程及采取的相关措施,对确保阳坡泉煤矿浅部煤炭资源开采安全至关重要,并可为类似条件下工作面回采提供防治水依据。In response to the risk of water inrush in working faces under shallow buried deep terrain river gully,taking the typical working face of Shanxi Hualu Yangpoquan Coal Mine as an example,based on the systematic analysis of the hydrogeological conditions,the water channel and the water source strength of the working face,it is concluded that the atmospheric precipitation and the surface water are the main water-filling sources of the working face,which are influenced by the communication of the water-conducting fracture zone after the mining of the working face,there is the risk of water inrush.Through the calculation of water source intensity and the evaluation of drainage capacity of the working face,the drainage capacity of the working face and its periphery is larger than that of the river water and the direct back irrigation of precipitation,which can meet the drainage requirements of the working face.Through taking multi-directional control measures for heavy rainfall,Nanshigou water and goaf water,and cooperating with drainage system control,the safety of mining working face under shallow buried deep terrain river gully is ensured,and the mining verification of the working face is obtained.The analysis process and relevant measures are very important to ensure the safety of mining shallow coal resources in Yangpoquan Coal Mine,and can provide the basis for prevention and control of water in mining face under similar conditions.
