Abstract: Aiming at the problems of large changes in rock formation, easy roof caving and roof leakage of the semi-coal-rock
roadway with weakly-bonded compound roof in Jingfang Coal Industry Co., Ltd., which seriously affected the driving speed of the
excavation working face, through on-site investigation, theoretical analysis, numerical simulation, laboratory experiments, field
industrial tests and other methods, this paper systematically revealed the failure mechanism of the surrounding rock in the
excavation working face of the roadway with weakly-bonded compound roof, and carried out the research on the stability of the
roof. It is of great significance to develop strong shielding equipment for fast excavation of the excavation working face to improve
the integrity of the roof of the excavation face and the quality of roadway anchorage for improving the driving and support speed of
the roadway with weakly-bonded compound roof and ease the tense relationship of mining and driving in the mine.

Key words: weakly-bonded; compound roof; support equipment
