Abstract
Aiming at the problems of deep burial,high ground pressure,thick coal seams,and low hardness in Wanfu Mine,the"anchor net cable belt"combined support scheme for the working face crossheading is determined through natural equilibrium arch theory,composite beam theory,and suspension theory.Referring to the experience of mines with similar conditions in Juye Coalfield,the roadway support parameters are determined using engineering analogy method,numerical simulation and ultimate plastic zone theory are used to check calculation the support parameters.After the on-site implementation of the support scheme,the surface displacement observation,drilling hole peek and etc of the excavation working face roadway are conducted to verify the support effect.The completeness of the roadway roof and the integrity of support are good,effectively controlling the deformation amount of the roadway and achieving safe and efficient support for the large cross section coal roadway.关键词
