摘　　要：山西潞安集团忻峪煤业为整合矿井,井田周边有数十个小窑采空区,受老空水威胁严重。为实现安全回采,在分析其水文地质条件的基础上,采用富水系数比拟法和地下水动力学法对矿井涌水量进行了预测,采用钻孔探放、截水巷、注浆堵水、泄水巷等措施对老空水进行了疏放。实践表明,疏放后工作面回采过程中水量较小,实现了安全回采,取得了较好的控制效果。Xingyu Coal Industry of Shanxi Lu’an Group is an integrated mine with dozens of small mining goaf areas around the mining field,which is seriously threatened by goaf water.In order to achieve safe recovery,based on the analysis of its hydrogeological conditions,the water-rich coefficient comparison method and the groundwater dynamics method were used to predict the mine’s water influx,and the goaf water was evacuated using measures such as drilling and releasing,water interception alley,slurry plugging and water drainage alley.The practice showed that the amount of water in the workings after sparing was small,achieving safe recovery and a better control effect.
