由于我国煤矿地质条件极为复杂,巷道支护作为一项重要的煤矿开发技术在煤炭资源开采中有着重要地位。而破碎围岩的广泛存在给煤矿巷道的安全带来巨大隐患。本文主要探讨破碎围岩的巷道支护技术,并简要介绍两种常用的处理技术,即锚注支护技术和锚网喷注耦合支护技术。
Due to the extremely complicated geological conditions in China’s coal mines, as an important coal mine development technology, roadway support plays an important role in the exploitation of coal resources. The widespread presence of crushed rock brings great hidden dangers to the safety of coal mine roadway. This paper mainly discusses the roadway supporting technology of broken surrounding rock and briefly introduces two commonly used processing technologies, that is, the bolt-grouting support technology and the bolting-grouting coupling support technology.
