摘要
在对深部巷道片帮破坏机理进行简要阐述的基础上，初步分析了某金矿深部开采巷道片帮的原因。喷锚网联合支护技术在提高围岩整体性方面具有明显优势，可作为深部巷道片帮治理的有效手段。阐述了喷锚网联合支护的主要工艺，并对主要支护参数进行了理论校核计算。实践表明，喷锚网联合支护技术对围岩具有良好的控制作用，在深部巷道片帮治理中取得了良好的支护效果。
Based on briefly reviews of the failure mechanism of wall caving in deep roadways, the reason of roadways wall caving of deep mining in a gold mine is preliminarily analyzed, shotcrete-bolt-mesh combined support technique has obvious advantages in enhancing the integrality of surrounding rock, and it can be used as an effective method in wall caving treatment. The main process of shotcrete-bolt-mesh combined support technique is introduced, and the main support parameters are verifying calculated in theory. Practice shows that shotcrete-boh- mesh combined support technique has favorable control action to wall rock, which got good supporting results in wall caving treatment of deep roadway.
