摘要：Aiming at the problems of slow excavation speed, large support workload, large number of assistants, high excavation and support cost in belt conveying roadway in a mine at present, the finite difference software FLAC3D is used to establish the numerical simulation model based on the production geological conditions, Through numerical calculation, reasonable supporting parameters such as bolt diameter, length, spacing between rows, number of anchor wire and spacing between the two are determined to support a belt conveying roadway, that realized the optimization of roadway support, improves the driving speed and guarantees the normal continuity of production.
