    The Surrounding Rock Control Technique of Deep Gob-side Entry Driving in Zhangxiaolou Coal Mine

    • 摘要: 随着煤矿开采深度的加大,深部巷道围岩控制技术现已成为深井安全高效生产的关键,这是深井煤矿亟待解决的问题。针对95206材料道深部沿空掘巷段,根据其围岩稳定性影响因素及深部沿空掘巷围岩控制原理,提出了高强锚网索耦合支护方案。现场试验表明,高强耦合支护体系能有效控制深部巷道围岩的稳定性,具有良好的技术经济效益。

       

      Abstract: With the increase of mining depth, the surrounding rock control technique in the deep roadway has become a the key to the safety and high effective product of deep mines, which needs to be further researched urgently in deep coal mines. This article mainly researches at 95206 material roadway deep gob-side entry driving. According to the key factors affecting the stability of surrounding rock and the surrounding rock control theory of deep gob-side entry driving, the coupling support scheme of higher strength cable and mesh has been put forward. Field practice has shown that the system that coupling support of higher strength cable and mesh can efficiently control surrounding rock stability of deep laneway, which has good technological and economical benefit.
