【摘要】 在阐明深部巷道围岩变形机理的基础上，对煤柱支承压力在底板传播规律和煤柱载荷在底板岩层传递影响角进行了分析，并结合实测资料，提出了测定煤柱影响角的方法，为深部开采底板巷道合理位置选择提供了依据。更多还原

【Abstract】 Based on the deformation mechanism of wall rock in deep roadway,this pa-per analyses the transmission law of pillar abutment pressure in floor and influence angletransference of pillar load in floor strata. In addition,this paper puts forward the method ofdetermining pillar influence angle,providing the basis for choosing reasonable place to exca-vate floor roadway.更多还原
