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 method and device for implanting gas pulsation quantum energy into pre-splitting and anti-reflection gas drainage. The invention uses pulsating gas to pressurize and pre-crack the coal seam, thereby solving the problem of uncontrollable gas explosion induced by liquid carbon dioxide phase change expansion blasting in the mining process, and improving the safety of gas mining. And it also solves the problem of weakening and permeability of soft coal seam, and the problem of high water pressure in coal seam fissure and hole closure, which reduces the difficulty of mining. Further implantation of quantum energy makes the gas more easily separated from the coal seam and improves the extraction efficiency.

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...
