摘要
针对大同矿区石炭系特厚煤层综放工作面沿空巷道破坏形式及特征,从采动状况、围岩结构、巷道布置,以及煤柱留设、开采接替、巷道支护等方面进行了原因分析,提出了类似条件下的巷道变形控制措施和解决方法。
From mining status,surrounding rock structure,roadway layout,coal-pillar dimension,mining replacement and roadway supporting,this paper analyzed deformation and damage reasons of roadway along gob in full-mechanized caving mining extremely thick Carboniferous coal-seam.It put forward measures and solution method for controlling roadway deformation under similar condition.
