摘 要:回收大巷保护煤柱时,保护煤柱内巷道众多且相互交错,严重影响煤柱工作面的安全回采,管理不规范易出现大面积片帮、冒顶事故。以某矿煤柱工作面过复杂老巷为研究背景,总结各类老巷加固及通过方法,为综采工作面过老巷提供了经验和借鉴。When protecting coal pillars in the main roadway for recycling,there are numerous and interconnected tunnels within the protected coal pillars,which seriously affects the safe mining of the coal pillar working face.Improper management can easily lead to large-scale slope fragmentation and roof fall accidents.Taking the coal pillar working face of a certain mine passing through complex old roadway as the research background,this paper summarizes various reinforcement methods for old roadway and provides experience and reference for the comprehensive mining working face passing through old roadway.
