摘要
针对目前镇城底矿760水平运输大巷南六采区正前地段存在脱皮、开裂、掉渣的问题,对矿井巷道围岩进行合理性分析;提出在确保巷道安全的前提下,巷道试用锚喷网支护技术,以保证安全生产。
In connection with the existing problem of peeling,cracking,dregs of the former location of South Sixth mining area in 760 level main haulage roadway of Zhengchengdi coal mine,analyzes the rationality of tunnel wall rock in the mine;proposes under the premise of ensuring roadway safety,try bolting-steelmesh-shotcreting support technology in the tunnel,so as to ensure safe production.
