Investigation of Gob Water Disaster-causing Factors and Its Control in Resource Integration Coal Mine
LIANG Qinghua
Abstract：At present, the resource integration coal mines are faced with a serious situation in mine water prevention due to their long mining time, more abandoned pits and mined-out areas, unclear gob data and unknown gob water accumulation. In this paper, analysis was made on the characteristics of water disasters in this mining area by taking Shanxi Heshangzui Coal Mine as an example, the hidden factors causing water disasters were found out by adopting both the surface and underground physical prospecting and exploratory boring methods, the gob water drainage schemes were worked out, and the control effect of the hidden disaster-causing factors were summarized. The study showed that the analysis on the geological and hydro-geological data was the basic and important method for the investigation and control of the hidden factors causing water disasters in the resource integration coal mine, the combination of the surface and underground physical prospecting was a better method for prospecting multilayer gob water accumulation, and the combination of exploratory boring and physical prospecting was a better way to drain multilayer gob water.
