新疆镜儿泉铜镍矿的地质构造情况特殊,开挖的巷道必须穿越软弱破碎带。分析了软岩巷道破坏的原因及软弱结构破坏失稳性的机理,结合软岩巷道的支护特点与支护原则,以及现阶段矿山巷道施工的特点,提出了该类矿山软岩破碎带巷道的支护方案。
The geological structure of the JingEr-Quan Cu-Ni deposit in Xinjiang is very special. The roadway for excavation must pass through the weak broken zone. This paper analyzes the reason of soft rock roadway destruction and the mechanism of damage and instability of weak structure. Combined with the supporting characteristics and supporting principles of soft rock roadway and the characteristics of mine roadway construction at this stage, Support program.
