疏水沉降矿区井壁外侧剪应力分布

Shearing stress distribution of outer shaft wall in drainage settlement coal field

本文在对疏水沉降矿区井壁破裂部位进行统计的基础上 ,从受力机理和力学原理出发 ,推理了全段井壁外侧剪应力分布的模型。该模型的建立将对疏水沉降矿区井壁的受力计算和井壁破裂预测具有现实的意义。

Based on the statistic in fracture zone of outer shaft wall in drainage settlement coal field, the paper uses the stress mechanism and mechanics analyses, and constructs the shearing stress distribution model of outer fall shaft wall. It has some real meaning for stress calculating and fractures zone forecasting on shaft wall in drainage settlement coal field.
