Roadway support parameters under complex surrounding rock geological conditions

The 432 belt crossheading of Tangyang Coal Mine is taken as the research object.The non-production side of the 432 belt crossheading is close to the 431 goaf, the upper part of the roadway is close to the-520 belt roadway, and the geological conditions of the surrounding rock are more complicated.Using theoretical analysis and numerical simulation, the stress environment of the working face is clarified, the reasonable coal pillar width and the safe spacing of the roadway are obtained; we optimize the support parameters and schemes, and determine the parameters and layout of bolts and anchor cables in different areas.Through on-site monitoring of 432 belt crossheading, it is verified that the support effect is good, the deformation of surrounding rock of roadway is effectively controlled, and the safe and efficient production of working face is guaranteed.
