摘　　要：新集二矿在对底板高承压灰岩含水层进行地面区域治理过程中,发现相邻新集一矿井田的推覆体含水层105#长观孔水位相应波动。通过对新集一矿采掘活动、新集二矿开采1煤层的区域治理、水文地质条件及历史观测资料等综合分析,确认前期开采结束后推覆体下含水层水位出现波动或恢复性上升,与高压注浆(注水)存在直接关系。In the process of surface regional treatment of the high pressure limestone aquifer in Xinji No.2 Mine, it is found that the water level of the nappe aquifer 105# long view hole in the adjacent Xinji No.1 Mine field fluctuates accordingly. Through the comprehensive analysis of the mining activities of Xinji No.1 Mine, the regional treatment of the 1 coal seam in Xinji No.2 Mine, the hydrogeological conditions and historical observation data, it is confirmed that the water level of the aquifer under the nappe fluctuates or recoverably rises after the end of pre-mining. It is directly related to high pressure grouting(water injection).
