摘要
Abstract
Aiming at the serious problem of roadway failure caused by asymmetric ground stress and diverse lithology in the roadway of the No.3 Coal Mine in Dayan Company,a series of on-site tests are conducted on the deformation characteristics,crack distribution,and surrounding rock loosening area of the roadway.The stress and crack distribution of the roadway surrounding rock,as well as the failure location of the roadway roof,are determined.After adopting comprehensive support and step-by-step joint control,the deformation of the roadway roof and surrounding rock at the side is significantly controlled.关键词
