摘要
调查数据显示,在巷道掘进过程中,顶板事故占整个煤矿事故的1/3。通过分析煤矿掘进巷道工作中存在的问题和影响因素,以及顶板支护技术,提出了顶板支护技术优化改进措施。该措施可以保证煤矿井下施工的安全性,使煤矿企业稳定发展,提高了煤矿企业的经济效益。
According to survey data,roof accidents account for one-third of all coal mine accidents during tunnel excavation.By analyzing the problems and influencing factors in coal mine tunneling work,as well as roof support technology,optimization and improvement measures for roof support technology were proposed.These measures can ensure the safety of underground construction in coal mines,promote stable development of coal mining enterprises,and improve their economic benefits.
