Prevent Outburst Mechanism of Water Pressure Blasting and Its Enginieering Application
Abstract：For the problems of high concentration of gas and low permeability of coal seam, regional gas control method based on water pressure blasting. Analysis the stress and crack change of coal, Numerical simulation of the effective radius of water pressure blasting, and the technology has been carried out in the domestic relevant mine. The application results showed that the technique obviously improved the efficency of gas drawing, and shortened the gas extraction time, which implied a broad industrial application prospect.
