【摘要】：分析了路天煤矿041606工作面水文地质条件,确定了充水水源主要为16号煤层顶板基岩裂隙承压水,顶板采动破坏带及断层为主要导水通道。采用钻探探放水、水化学测试分析、水文地质调查、测绘等手段对041606工作面回风巷断层出水水源进行了综合探查,从来水方向、水压、水化学特征离子综合判别出水水源为顶板基岩裂隙承压水和041604采空区积水共同作用所致,与F公逆断层二采区剥采坑积水无直接水力联系。基于对巷道过断层面的总水量分析及探放水钻孔引流效果评价,认为回风巷掘进前方断层导水不会对巷道掘进构成威胁。
[Abstract]:The hydrogeological conditions of No. 041606 working face in Lutian Coal Mine are analyzed. It is determined that the water source of water filling is mainly confined water from the fissure of roof rock of coal seam No. 16, and that the failure zone of roof mining and fault are the main channel of water diversion. By means of drilling water exploration, hydrochemical test and analysis, hydrogeological investigation and surveying and mapping, this paper makes a comprehensive exploration of the outlet water source of the fault in the return wind lane of 041606 working face, and the direction and pressure of the water are obtained. The water chemistry characteristic ion synthetically discriminates that the outlet water source is caused by the joint action of the roof bedrock fissure confined water and the 041604 goaf water, and has no direct hydraulic relation with the stripping pit water in the second mining area of F Gongreverse fault. Based on the analysis of the total water quantity of the roadway passing through the fault plane and the evaluation of the drainage effect of the drilling hole, it is considered that the fault water diversion in front of the backwind roadway excavation will not pose a threat to the roadway excavation.
