Abstract

Taking the floor rock roadway of 10414 working face of Yangliu Coal Mine in Huaibei as the engineering technology background, this paper uses theoretical analysis and numerical simulation technology to analyze the stability of floor rock roadway caused by stope mining. According to the dynamic pressure of stope, the support stage is divided into three stages: timely support scheme after excavation, pre-mining reinforcement support stage and post-mining repair support stage, and corresponding suggestions are put forward. Support scheme, through field practice, the overall maintenance of roadway affected by dynamic pressure is in good condition, the deformation of roof, floor and both sides are within the controllable range, and the roadway section can meet the requirements of normal use.
