摘要
盖州煤矿9105工作面回采受残留3号老空水和上部导水裂隙带的影响,涌水量较大。本文结合实际情况,探讨了导水裂隙带观测基本原理,并根据盖州煤矿9105工作面实际地质情况进行了观测方案设计和实地观测,结果表明2个观测孔的数据较为一致,确定了导水裂隙带的高度。
The 9105 working face of Gaizhou Coal Mine is affected by goaf water and the upper water-conducting fracture zone, and the water inflow is large. Based on the actual situation, this paper discusses the basic observation principle of water-conducting fracture zone, and designs an observation scheme according to the geology of the 9105 working face in Gaizhou Coal Mine. The results show that the data of the two observation holes are relatively consistent, and the height of water-conducting fracture zone is determined.
