张双楼煤矿井筒变形原因分析

Cause analysis of shaft deformation in coal mine of Zhangshuanglou coal mine

通过分析张双楼煤矿工业广场范围内主井、副井、新副井投产以来的井筒沉降、偏斜数据,结合区域地层特征、含水层水位变化情况、水源井位置分布以及井筒受力变化规律综合分析,总结出井筒变形的3个主要原因,对其它条件相似矿井具有指导意义。

This paper analyses the changing regularity of shaft pressure , position distribution of water source well , water level variation of aquifer , stratigraphic features in combined area , skewed data and the shaft subsidence of new auxiliary shaft , auxiliary shaft and main shaft within the scope of Industry square in Zhangshuanglou coal mine , and 3 main reasons of shaft deformation are summarized.
