摘要
Abstract
In the construction of the large cross section coal roadway in Jinjie Liangshuijing Coal Mine,based on FLAC3D numerical simulation,the stress evolution laws of the surrounding rock are analyzed.Combined with the synchronous excavation and support technology of MB670 digging and anchoring integrated machine,measures such as empty roof distance control,anchor rod length adjustment,tension force optimization and so on are proposed.The results show that the optimization scheme significantly decreases the deformation rate of the surrounding rock,reduces the risk of support instability,improves the construction efficiency and safety,and provides technical support and practical basis for the construction of large cross section coal roadways under complex geological conditions.关键词
