煤层气与煤炭协调开发的关键在于协调煤炭开采与煤层气开发的时空关系。"十一五"至"十三五”期间,依托国家科技重大专项“大型油气田及煤层气开发”项目的总体实施,煤矿区煤层气与煤炭协调开发机制取得巨大进展。煤矿区煤层气开发由最初为保障煤矿安全生产的“瓦斯抽排”“煤层气抽采""地面开发和井下抽采相结合"等形成"煤矿区煤层气与煤炭协调开发"的技术开发新机制。通过界定煤层气与煤炭协调开发范围、建立煤层气与煤炭协调开发评价方法、形成煤层气与煤协调开发优化决策平台,提出基于"协调开发、提质增效、技术支撑、平台决策、集成示范"的煤矿区煤层气与煤炭协调开发理念,依托煤层气与煤炭协调开发技术体系等成套技术系列,形成山西矿区煤层气“四区联动”全域协调开发模式、两淮矿区煤层群煤层气立体联合开发模式、松藻矿区复杂松软煤层超前增透协调开发模式、新疆矿区大倾角多煤组”三位一体”协调开发模式、进而带动全国煤矿区信尽气开发实践。煤矿区煤层气与煤炭协调开发机制、模式与应用引领了我国煤矿区煤层气行业科技创新,显著提升煤矿区煤层气开发利用水平。随着国家能源战略的调整,“双碳”战略的实施和生态文明建设等新形势新要求,煤矿区煤层气发展面临新需求新挑战,指出需重点推进煤矿区煤层气地质精细探查、并下煤层气高效开发、废弃矿井煤层气抽采、煤系气协同共采等技术研发,构建煤矿区煤层气与煤炭清洁高效开发的新技术体系。
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, atotal 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
