摘　　要：针对敏东一矿首采盘区顶板富水条件下的水害防治难题,根据收集到的地质钻孔柱状资料数据,采用“基于关键层位置的导水断裂带高度预计方法”,对首采盘区01~04工作面的导水断裂带发育高度进行了预计,结果分别为82.80、83.06、45.65、61.10 m。同时,利用导水裂隙发育的钻孔工程探测对02工作面预计结果进行了验证,证实了理论预计结果的准确性。In view of the problem of water hazard prevention under the condition of water-rich roof of the first mining panel in Mindong No.1 Coal Mine,based on the data collected from the geological drilling column,the“height prediction of fractured water-conducting zone based on the key stratum position”was adopted to predict the height of the fractured water-conducting zone in the first mining panel from 01 working face to 04 working face,and the results were 82.80 m,83.06 m,45.65 m,and 61.10 m respectively.At the same time,the prediction result of 02 working face was verified by drilling engineering exploration of aquifer fissure development,the accuracy of the predicted results were verified.
