摘要
介绍良山铁矿地下开采工程中所遇到的地质安全隐患,对此制定了减小采场冒顶风险的措施并严格实施,有效避免了井下开采施工过程中安全事故的发生。
The geological safety problems which encountered in underground mining engineering are introduced in Liangshan iron mine. The measures for decreasing stope roof collapse risk are made and strictly implemented,which effectively prevent safety accidents in the construction process of underground mining.
