摘　　要：地应力是巷道围岩发生变形破坏与运动的根本动力,因此在地应力实测的基础上,对综放沿空掘巷锚杆支护参数进行优化设计。首先,采用应力解除法进行了地应力实测,在此基础上,采用FLAC^(3D)对综放沿空掘巷锚杆支护参数进行模拟计算。通过对比分析提出了巷道的优化支护方案,并进行现场应用。在应用过程中,对巷道围岩变形进行监测。Geostress is the root of roadway surrounding rock deformation failure and movement,therefore, based on the geostress measurement, to design bolting parameters optimization of roadway driving along goaf in fully mechanized caving mining. First of all, the stress relief method is used for the geostress measurement, on this basis, FLAC3 Dis used for simulated calculating bolting parameters of roadway driving along goaf in fully mechanized caving mining. Put forward the optimized scheme of roadway support by comparing and analysis and conduct the on-site application. In the process of application, monitor roadway surrounding rock deformation.
