摘要
主要围绕如何能安全经济地把巷道保留住的问题,分别从沿空一侧巷旁支护体的材料和性能的选择方面、沿空留巷技术设计及参数确定方面、木垛与密集支架增强支护积极控制围岩变形方面,分析选择支护参数,满足生产技术要求。沿空留巷可以最大限度回收资源,避免煤体损失,同时无煤柱开采方案可有效地控制瓦斯爆炸、冲击地压等相关事故的发生。
This paper focuses on the safety and economy of the roadway can retain, respectively from the material and performance along the empty side of roadside barrier option; gob technology design and parameter determination;enhance support actively control the surrounding rock deformation using wood and intensive support, analysis and selection of support parameters to meet production technical requirements. Along the goaf can maximize the recovery of coal resources, to avoid losses, while non coal pillar mining scheme can effectively control the gas explosion, rockburst and other related accidents.
