Study on Influence of Coal Seam Water Infusion Pressure upon Infusion Effect
LUO Dayong
Abstract：In this paper, analysis was made on effect of water pressure in coal seam water infusion, numerical simulation was carried out on the seam water infusion in a heading face in the experimental mine, and the variation relation between the water infusion pressure and the coal breaking degree in the fracturing process was obtained. The simulated results were used to optimize the water infusion pressure in the coal face of the mine, better effect was achieved. This thus provided a method for the selection of the appropriate infusion pressure.
