9号煤层导水裂隙带高度探测研究

Height Survey of Water-conducting Fracture Zone of No.9 Coal Seam

导水裂隙带高度的确定对于煤矿防治水具有十分重要的意义。考虑到根据理论公式计算的导水裂隙带高度与实际情况存在较大的误差,需现场对导水裂隙带高度进行测量。结合9号煤层的实际情况,确定了导水裂隙带的探测方法及方案,探讨了导水裂隙带高度探测的实施,可以为煤矿导水裂隙带探测提供一定的参考。

The determination of the height of water-conducting fracture zone is of great significance for water control in coal mines.Considering that there is a large error between the height of the water-conducting fracture zone calculated according to the theoretical formula and the actual situation,it is necessary to measure the height of the water-conducting fracture zone on site.Combined with the actual situation of No.9 coal seam,the survey method and scheme of water-conducting fracture zone were determined,and the implementation of the height survey of water-conducting fracture zone was discussed,which can provide some reference for the survey of water-conducting fracture zone in a coal mine.
