Abstract: Under the dual action of the excavation disturbance and the stopping advance influence of the working face, the roadway of driving in the direction of the coal face has different degrees of influence of the advance support pressure and the lateral support pressure of the goaf at different intersection positions; the mine pressure appears violently, the roof of the roadway is incomplete, the surrounding rock is broken, and it is difficult to control. In order to ensure the integrity of roadway roof and improve the stability of roadway, the evolution characteristics of rock pressure in roadway surrounding rock are analysed. By establishing the mechanical model of surrounding rock structure, the mechanical characteristics of rock layer that covers the coal seam are researched, and the influence range of surrounding rock in roadway is analysed. Based on the control theory of roadway surrounding rock, the control principle of roadway surrounding rock is analysed.

Keywords: drive in the direction of the coal face; surrounding rock; stability; reinforcement by sections; optical fibre monitoring.
