摘 要:针对深层煤炭开采的巷道支护技术问题,阐明了采掘巷道围岩的破坏变形机理,对锚杆锚索联合支护技术进行了力学分析及参数设计,利用FLAC3D软件进行支护效果数值模拟试验,结果表明锚杆锚索支护技术对控制巷道顶板下沉量和围岩内最大主应力作用明显,验证了在深层煤炭开采中锚杆锚索联合支护技术的有效性。Aiming at the technical problems of roadway support in deep-seated coal mining,the mechanism of damage and deformation of the surrounding rock of the mining roadway is clarified,the mechanical analysis and parameter design of the combined anchor rod and anchor cable support technology are carried out,and the numerical simulation test of the support effect is conducted by using FLAC3D software.The results show that the anchor rod and anchor cable support technology has a significant effect on controlling the sinkage of the roadway roof and the maximum principal stress in the surrounding rock.
