摘要
基于宝积山矿705工作面巷超前区域冲击显现事件频发的问题,本文从理论上对巷道发生冲击事件进行了分析,并依据理论研究结果,提出了采取锚网索支护+高压水射流巷帮卸压的防治冲击技术,数值模拟结果表明该方法能够有效的降低巷道围岩应力分布,现场应用效果良好。该研究成果为受采动等动压扰动影响的巷道超前区域围岩稳定性改善提供一定的控制理论和现场指导意义。
Rock burst incidents appeared frequently at Baojishan Mine＇s 705 working face. This paper theoretically analyzed these events, and based on the theory of research results, proposed to take pressure relief control technology such as cable anchor support and high-pressure water iet. The numerical simulation results and field application effect showed that this method could effectively reduce the surrounding rock stress distribution. The results provided certain control theories and field guidance for the improvement of the stability of surrounding rock of roadway under the influence of mining-induced dynamic pressure disturbance.
