摘要
迎采动工作面沿空掘巷受超前采动支承压力和侧向支承压力叠加的影响,巷道围岩应力增加,巷道产生大变形。结合下梨园矿工程地质条件,采用数值模拟计算的方法,对迎采工作面沿空掘巷煤柱的合理宽度进行研究。
The roadway driving along goaf and heading for adjacement advancing coal face is influenced by advance abutment pressure and lateral abutment pressure, the surrounding rock will occur large deformation and high stress. Based on geological condition of Xialiyuan mine, numerical simulation is used to study the reasonable pillar width of rodyway driving along goaf and heading for adjacement advancing coal face.
