摘要
煤矿地下开采过程中需要掘进大量的巷道,然而在巷道掘进过程中有时会遇到复杂的地质条件。实现复杂地质条件下巷道的安全掘进,是煤矿企业需重点关注的内容之一。首先,分析了煤矿掘进过程中几种不利的地质条件,主要有高应力、软岩、地质构造、瓦斯突出危险性和承压水等;然后,探讨在复杂条件下实现安全掘进的措施,主要有做好地质勘探工作,做好安全预警和预案,做好现场施工管理工作和采用先进的掘进技术。希望所述内容可以为复杂地质条件下煤矿巷道的安全掘进提供一定的参考。
In the process of underground coal mining, a large number of roadways need to be excavated. However, complex geological conditions are sometimes encountered during roadway excavation. Achieving safe excavation of roadways under complex geological conditions is one of the contents that coal mining enterprises need to focus on. Firstly, this paper analyzed several unfavorable geological conditions in the process of coal mine excavation, mainly including high stress, soft rock, geological structure, gas outburst risk and confined water, etc.;secondly, this paper discussed the measures to realize safe excavation under complex conditions, such as do a good job in geological exploration, do a good job in safety early warning and plan, do a good job in on-site construction management and use advanced tunneling technology. It is hoped that the above content can provide certain reference for the safe excavation of coal mine roadways under complex geological conditions.
