摘要：

The key to coordinated development of coal mine methane and coal is to coordinate the spatio-temporal relationship between coal mining and coal mine methane development. During the “11th Five-Year Plan” and “13th Five-Year Plan” period, relying on the overall implementation of the national major science and technology project “Development of large oil and gas fields and coal mine methane”, the coordinated development mechanism of coal mine methane and coal in coal mining areas has made great progress. The development mechanism of coal mine methane in coal mine area is formed by “gas drainage”, “coal mine methane extraction”, “combination of ground development and underground extraction” and so on to ensure the safety of coal mine production. By defining the scope of coordinated development of coal mine methane and coal, establishing the evaluation method of coordinated development of coal mine methane and coal, forming the optimization decision-making platform of coordinated development of coal mine methane and coal, the concept of coordinated development of coal mine methane and coal in coal mine area based on “coordinated development, quality and efficiency improvement, technical support, platform decision-making, integrated demonstration” was put forward. Relying on the coordinated development technology system of coal mine methane and coal, as well as a complete set of technologies such as efficient extraction and effective utilization of coal mine methane in coal mining areas, Formation of coal-bed methane mining area in shanxi area “four linkage” global coordination development mode, huaibei mining area coal seam group of coal mine methane (CBM) three-dimensional joint development pattern, the complex soft Songzao mining area coal seam ahead of anti-reflection coordinated development pattern, Xinjiang mining area coal group “trinity” of large dip Angle coordinate development mode, leading to the coal mining area of coal bed methane development practice. The coordinated development mechanism, model and application of coal mine methane and coal in coal mine area have led the scientific and technological innovation of coal mine methane industry in coal mine area, and significantly improved the level of coal mine methane development and utilization in coal mine area. With the adjustment of national energy strategy, the implementation of the strategy of “double carbon” and the new requirements of the new situation, such as construction of ecological civilization coal mining area of coal bed methane development faces new challenges, new demand on promoting fine coal mining area of coal mine methane geological exploration and underground coal bed methane efficient development, abandoned mine coal mine methane extraction, such as coal gas together, a total of mining technology research and development, To construct a new technology body for clean and efficient development of coal mine methane and coal in coal mine area. © 2022 Editorial Office of Chinese Journal of Schistosomiasis Control.
