CAUSE ANALYSIS OF MAIN AND AUXILIARY SHAFT RUPTURED IN BAODIAN COAL MINE AND ITS CONTROL
The main and auxiliary shafts in Baodian Coal Mine are deformed and ruptured,threatening seriously on the mine safety and causing heavy economic losses.Based on the observation and analysis,it is considered that the fracturing causes are land subsidence resulted from the dropdown of water table in Quaternary aquifer.Meantime,the control countermeasures of shaft fracturing are put forward.
