ABSTRACT

Based on the data of geological drill holes, roadway drifting, transient electromagnetic exploration, mine water inrushes, hydro-geochemistry and water levels on each side of the Haotang Normal Fault, this paper studies the waterbearing capacity and water conductivity of the fault in the Pingdingshan Tian’an Mining Company Limited No. 7 Coal Mine. The results indicate that the Haotang Fault is subject to compressive or shear-compressive stresses. The waterbearing capacity and water conductivity of the fault is poor. The water content of the Cambrian limestone in footwall is higher than that in hanging wall, and the mining threat of 15 coal seam in the south district (footwall) is greater than that in the north district (hanging wall).
