摘要
鲍店煤矿主副井筒变形破裂，严重威胁矿井安全，经济损失巨大。通过观察分析，认为变形破裂乃第四系水位下降引起的地面沉降所致，并据此提出了防治对策。
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.
