Deformation and failure of high drainage directly affects the gas extraction, restricts the gas mine of high production and effi-ciency.According to the high alley pumping damage form, this paper analyzes the formation mechanism of floor heave, establishes high drum alley pumping at the end of the mechanics model, finding out the high alley pumping deformation damage regular;Based on the theory of shell bolting, Combined with the deformation and failure of shanxi five Yang mine 7603 working face high alley pumping, this paper determined the 7603 face high alley pumping supporting method and parameters.
