摘要
Abstract
In response to the difficult problem of controlling the heaving floor of the return air roadway in the 02 working face of Wuyang Coal Mine,a combination method of on-site observation,theoretical calculation,numerical simulation,and on-site industrial testing is adopted to study the deformation and failure characteristics of the roadway heaving floor.A floor"drilling pressure relief"and"reinforcement support"scheme is proposed for floor control.The deformation amount of the floor is 90-120 mm,and the control effect of the roadway heaving floor is good,which can ensure the safe use of the roadway.关键词
