摘要
某工作面为孤岛煤柱回收工作面,南北两翼为采空区,因此在掘进过程中严格执行作业规程要求,比对安全生产标准化和煤矿重大隐患判定标准要求,解决掘进过程中存在的问题,确保掘进工作安全顺利地开展.指出了煤柱回收工作面在掘进过程中可能存在的各种困难,讨论分析确定了安全技术的管控措施,以确保顺利开展顺槽掘进工作.
Abstract
The coal pillar recovery face is coal pillar recovery face in an isolated island.The south and north wings of face are mined-out areas,so in the course of excavation,the requirements of operation regulations are strictly implemented,and the standards of safety production standardization and major hidden danger judgment of coal mine are carefully compared,so as to solve the problems existing in the process of excavation,to ensure that face excavation work can be carried out safely and smoothly.The study introduces in detail all kinds of difficulties that may appear in the driving process of coal pillar recovery working face of isolated island,and discusses and determines the prevention and control measures of safety technology,so as to ensure the smooth development of the tunneling work.
