郑煤集团老君堂煤矿由于受区域滑动构造的影响，矿井水文地质条件复杂。其中，21081工作面下巷在掘进过程中，受滑动构造及隐伏断层影响，底板完整性遭到破坏，导致底板断裂造成突水。基于掘进面的突水原因，采取了变动为静的注浆堵水加固技术，通过此技术的应用，使21081下巷底板突水现象得到控制，矿井总涌水量下降30％，缓解了矿井排水压力，对矿井安全生产具有重要意义。
鄭煤集糰老君堂煤礦由于受區域滑動構造的影響，礦井水文地質條件複雜。其中，21081工作麵下巷在掘進過程中，受滑動構造及隱伏斷層影響，底闆完整性遭到破壞，導緻底闆斷裂造成突水。基于掘進麵的突水原因，採取瞭變動為靜的註漿堵水加固技術，通過此技術的應用，使21081下巷底闆突水現象得到控製，礦井總湧水量下降30％，緩解瞭礦井排水壓力，對礦井安全生產具有重要意義。

The hydrogeological conditions of Zhengzhou coal group Laojuntang coal mine is complex due to the effect of regional sliding structures.Among them,in the excavation process of lower roadway in 21081 working face, floor integrity is destroyed and caused the floor fracture and water bursting because the affect of sliding structure and concealed fault.Based on the reason of excavating face water inrush,by taking the grouting water plugging reinforce-ment technology,controlled the water inrush phenomenon of 21081 working face roadway,reduced about 30%of total water inflow in the mine,alleviated the pressure of mine drainage,have great significance to mine safety production.
