Abstract: To solve surrounding rock support problem of mining roadway with thick top coal and large section in Madaotou Coal Mine, the engineering situation and failure characteristics of mining roadway in fully mechanized caving panel were researched in this paper. The factors affecting the stability of the surrounding rock were analyzed. Based on the existing support theory and numerical simulation, the support scheme was studied and the stability of surrounding rock was analyzed. Site geological conditions, numerical simulation results, theoretical analysis results and engineering analogy were used to determine the bolt-net-cable support scheme of coal roadway and the field experiment was carried out.
