Abstract: In order to solve the problems of unstable roof and difficult support of roadway roof in composite roof, taking Lane 5101 of Zhaozhuang Mine as the engineering background, the loose and broken range is determined to be 0～7m by peeping at the internal structure of the roof. Based on this, the stability degree of roadway roof with composite roof is divided into stable layer, sub-stable layer and unstable layer, and a multi-level combined roof support scheme of long-short anchor cable and long bolt support is put forward. After the application of the support scheme in the field, the mine pressure monitoring results show that this support technology can effectively control the roof subsidence and ensure the stability of roadway surrounding rock.
