摘要 根据回采巷道两帮压裂失稳和剪切失稳破坏模型,对喷锚支护条件下回采巷道两帮稳定性及喷锚复合支护的合理支护阻力进行了研究。认为在分析回采巷道两帮围岩锚固体破坏特征及作用机理的基础上,按照剪切失稳破坏形态对深井回采巷道两帮进行设计能够确保安全。在上述分析的基础上,提出了锚喷支护条件下两帮喷锚支护的支护阻力计算方法,可为巷道支护设计施工提供参考。

Abstract: According to the model of fracture instability and shear instability failure of two sides of mining roadway,the reasonable support resistance of two sides of stability and the composite support of bolting and shotcreting under the condition of bolting and shotcreting support are studied.On the basis of analyzing the failure characteristics and mechanism of two sides of rock bolts and solids in the mining laneway,it is considered that the design of the two sides in the deep well mining roadway is partial to safety according to the shear instability failure model.Based on the above discussion results,the design and calculation method of the support resistance of two sides of bolting and shotcreting support under the condition of bolting and shotcreting support is put forward.The above study conclusions can be used as a reference for the reinforcement mechanism and design of bolting and shotcreting support.
