摘要
随着我国煤矿资源的枯竭,为了保证煤炭资源的正常供应,越来越多的煤矿企业开始向着更深的煤层开采,煤层的深层开采工作中,大断面的破碎围岩的硐室变形情况比较严重,本次研究结合具体的工程现状,探索围岩支护的具体原则,并且研究出合理的支护方案。
along with our country’s coal resources dried up,in order to ensure the normal supply of coal resources,coal mining enterprises in growing Numbers are beginning to towards deeper coal seam mining,the deep mining of coal seam,the big cross section deformation of crushed surrounding rock of cavern situation is serious,the research present situation of combined with specific engineering,explore the specific principle of surrounding rock bolting,and study out the reasonable supporting scheme.
