Abstract. A method of and technical equipment for preventing coal and gas outbursts during the mining operations in the gas-bearing coal seams are described, which assume seam drilling from the face and further high-pressure injection into the drilled wells. The proposed method assumes that a drilling rig and high-pressure injector move together on the scraper conveyor frame with the help of carriages, which are connected with the scrapers of conveyor installed on the tunnel floor. The wells with diameter of 50 mm and length of at least 25.0 m are drilled by the drilling rig. A modular complex is described, which is designed for preventing gas and coal outbursts (hereinafter the MCPO) during the mining operations in the gas-bearing seams, and which consists of a bore, bore bar, rock cutting tool for drilling blastholes or wells and high-pressure pumping plant for pumping fluid into the coal seam through the blasthole or well. The MCPO differs by its design in which drill bit and pump are arranged on two separate carriages installed on the scraper conveyor frame at a distance of not less than 30 m from each other. As the carriages are connected with the conveyor scraps by anchors they can move simultaneously along the whole length of the face. This method and equipment essentially improves the MCPO mobility, drifting rate and safety of miner labor.

Keywords: outburst, drilling rig, scraper conveyor, aggregate complex, high-pressure pump installation.
