Problems solved by technology

The existing problems are that firstly, the high-pressure water in the injection fracturing process will easily cause the high-pressure water to seal itself in the coal seam, which will induce coal seam gas outburst; secondly, for some pulverized coal, the immersion of a large amount of water will sometimes block the joints and fissures, reducing the coal seam. The permeability of the body; the third is that the equipment process is complicated, the installation and transportation are cumbersome, and the overall cost is high

Abstract

The invention provides a gas pulsation quantum energy implantable presplitting anti-reflection gas extraction method and device. According to the invention, pulsating gas is used for pressurizing andpresplitting a coal seam, so that the problem of gas explosion caused by uncontrollable phase change expansion blasting of liquid carbon dioxide in the mining process is solved, and the gas mining safety is improved. Moreover, the problems of weakening permeability of the soft coal seam and high water pressure sealing of cracks and holes of the coal seam are solved, and the mining difficulty is reduced. Furthermore, the gas more easily breaks away from the coal seam through quantum energy implantation, so that the extraction efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of underground gas control in coal mines, and in particular relates to a gas pulsation quantum energy implanted pre-splitting anti-permeability gas drainage method and device. Background technique [0002] Improving the permeability of the coal seam and effectively discharging the gas in the coal seam is one of the most powerful measures to prevent and control gas coal and gas outburst in the mine area. The gas content and pressure of the coal seam can be reduced through gas drainage, thereby eliminating the hidden danger of coal and gas outburst. At present, waterjet cutting and drilling technology is mainly used in China, using CO 2 Phase change and high pressure water fracturing of coal seams improve the permeability of coal seams. [0003] CO 2 Phase change fracturing technology uses liquid CO 2 A physical blasting technology developed by rapidly vaporizing and expanding at a certain temperature. Th...
