摘要
通过对回采巷道内的岩体结构——“壳”的内力及位移分析,探讨了具有不同特性的巷道支护体与其相互作用的关系,从而提出了控制岩体结构运动,提高巷道稳定性。
In surrounding rock of actual mining roadway there exists a rockmass structure similar to the ′structure′ in cover strata of working face—cowl, its formation and movement is mainly affected by characters of supports and surrounding rock, mining processes, supporting patterns, etc. The paper gives an approach to the interaction relation between roadway supports with different working characters and rockmass structure on the basis of its internal stress and displacement, and puts foward the basic ways in controlling structure movement and improving roadway stability as well as decreasing support and surrounding rock deformation of the roadway.
