Abstract: In order to solve that the phenomenon of roadway Floor heave, wall heave, in a coal mine in the northern mining area of Ordos coalfield comprehensive face wind back tunnel, caused by impact pressure，a kind of anti-impact advance hydraulic support was designed. Based on the actual conditions of the roadway, the main technical parameters of the scaffold are determined by theoretical calculation and the analysis of the measured results. By observing the actual use of the site, the anti-impact leading hydraulic support can effectively solve the phenomenon of roadway bottom drum and drum, reduce the incidence of safety accidents, protect the safety of operators and equipment, and provide a new type of technical reference for roadway leading support.
