Abstract: In order to reasonably determine the form and parameters of the roadway support for the near-distance coal seam mining in the overlying goaf in Hengtai Nanzhuang Coal Industry, the height of the falling arch, the roof pressure of roadway, the failure depth of roadway side and the side pressure of roadway were calculated based on balanced arch theory by studying and analyzing the information of the goaf of overlying coal seam corresponding to the layout area of coal seam mining roadway, the thickness of the coal pillar and the overlying rock layer, and the physical and mechanical parameters of roadway roof.According to the characteristics of the layered and block-like discontinuous rock mass of roof, the safety of roadway anchor and anchor cable support was theoretically calculated by combining the extrusion reinforcement theory, the composite beam theory and the suspension theory.The material mechanics simply-supported beam theory was used to calculate the safety of scaffolding support and the safe subsidence of scaffolding beams.The study proves that when the overlying area is a non-destructive coal pillar, the mining roadway is supported by anchor net beam cables, and when the overlying area is a goaf, the mining roadway is supported by U-shaped steel frame shed to meet the needs of mining roadway excavation and later mining.
