摘要
针对东滩煤矿北轨大巷巷道支护难题,提出了适用于深井软岩的新型"缓释、阻断和增强"复合支护技术体系,可以最大限度地提高软弱岩体自身强度和围岩主动承载的效果,最终形成围岩-支护结构协同承载体系。经过工程实践验证,新型支护技术最终控制巷道变形量在0.8%~1%,工程应用效果良好。
Corresponding to the problem of roadway support in the north track of Dongtan coal mine. The new ＂slow release, blocking and strengthening＂ composite support technology system for deep well soft rock is put forward, which can improve the strength of weak rock mass and the active bearing capacity of surrounding rock, and finally form the surrounding rock-collaborative bearer system. After engineering practice, the new support technology eventually controls the deformation of roadway in the range of 0.8%- 1%, and the application effect is good.
