摘要

View of the high stress, high gas coal seam characteristics and the current process of regional gas control problems, regional gas control method, based on drilling-blasting-fracturing-extracting integration technology were investigated by theoretical research, numerical simulation and field testing. Composite sealing technology has been carried out in the domestic relevant mine. The application results show that the technique obviously enhance the drill effective range, reduced the quantity of drills, shortened the gas extraction time and eliminated the outburst risk of coal mines which implied a broad industrial application prospect.
