沿空送巷小煤柱的留设及应用

Retaining and Application of Small Coal-Pillar

通过对沿空送巷小煤柱留设意义的分析认识,从煤巷两帮煤体应力和极限平衡理论、极限平衡非圆形巷道的圆形标准化理论方面对祁东煤矿现场进行方案设计,对现场有较强的指导意义,具有一定的推广应用价值。

By analyzing and understanding the significance of small coal - pillar retaining , the programs are designed at Qidong Coal Mine according to coal stress of coal roadway ribs and limited equilibrium theory, and the circular standardized theory of limited equilibrium non - circular roadway. There are more direction significances for field engineering. It has some value of generalization and application.
