Coal roadway in the tunnel after the need to take timely support, otherwise the roadway will produce deformation or damage. The choice of the concrete support mode is mainly determined by the geological conditions of the coal seam and the surrounding rock. Due to the complicated geological conditions of the coal seam and the coal seam quality conditions of each coal mine Which is not the same, there is no standard method of calculating the ground pressure. Therefore, the finite element method is used to analyze the stress of the surrounding rock of the mine roadway. Taking the coal roadway excavation of Yang quan Coal Group as the research object, by studying the relevant geological parameters, The finite element analysis software ANSYS analyzes the stress and deformation of the roadway under the unsupported roadway in the roadway and the surrounding rock. The analysis result is the support way of the roadway and the supporting structure choose to provide reference.
