Abstract: In order to accelerate the research and application of coal mine gas drainage and utilization technology, this paper systematically sorts out the development process of the transformation from coal mine gas pumping to gas drainage in China, summarizes the accurate and effective drainage technology of typical coal mine gas in China, and comprehensively introduces the latest application of coal mine gas safety gathering and transportation and full-concentration utilization technology, in order to provide reference for coping with the challenges of gas drainage and utilization and accelerating the development of coal mine gas drainage and utilization technology. The 1930s-1950s of the 20th century was the initial stage of coal mine gas pumping in China, mainly in Fushun City, Liaoning Province, Yangquan City, Shanxi Province, Tianfu District, Chongqing and other areas, the underground drilling method was used to drainage the gas of the coal seam and the gas of the upper adjacent layer to ensure the safety of mining; In the 60s and 70s, good results were achieved in the prevention and control of gas overrun and accidents in Jixi City, Heilongjiang Province, Shuicheng City, Guizhou Province and other mining areas, and the adjacent layer gas drainage technology was developed, and the methods of hydraulic cutting, controlled pre-cracking blasting, and water jet reaming were tested for low permeability coal seams. Since the 80s of the 20th century, with the substantial increase in the amount of gas gushing from the working face, various methods such as coal seam gas pre-drainage, adjacent layer gas drainage and goaf gas drainage have been applied to effectively drainage the pressure relief gas, but the progress of gas utilization is slow. After entering this century, the understanding of coal mine gas has changed from a single disaster attribute to a symbiotic genus of disaster and resources, and gradually realized the transformation of gas pumping into gas drainage, and combined with the differences in gas geological conditions in different mining areas, a gas drainage model has been formed with the joint mode of linkage shafts in Jincheng four districts, the mining mode of the protective layer of the two Huai crushed soft coal seams and the hydraulic enhancement and permeability enhancement model of Songzao. Other companies have taken the lead in developing and forming safe conveying technologies and devices such as water seal fire arrest and explosion venting devices, dry flame arresters, water mist and automatic powder spraying explosion suppression devices, which have been widely used. In terms of gas utilization, the research and development and application of gas power generation, direct current oxidation, porous medium combustion, fuel cell, regenerative oxidation and other technologies provide technical support for the "full concentration" utilization of coal mine gas. Coal mine gas drainage still faces the problems of poor universality and high cost, and the drainage technology mainly faces the challenge of poor economy. In the future, the development of coal mine gas drainage and utilization technology is expected to focus on the development of the ten-year planning area gas advanced pre-drainage technology system, the expansion of coal and gas co-mining mode, the source optimization of all aspects of gas utilization, the improvement of the intelligent level of gas drainage pipe network, and the joint research of government-industry-academia-research to help the implementation of gas utilization projects, so as to realize the full concentration utilization of coal mine gas and help the realization of the dual carbon goal of the coal industry.
