Recently, the Ministry of Industry and Information Technology of the Ministry of Environmental Protection of the National Energy Administration issued the "Opinions on Promoting Green Development and Clean and Efficient Utilization of Coal Safety." By 2020, the level of productivity in the coal industry will increase substantially, resources will be appropriately developed, and the level of clean and efficient use of coal will increase significantly. Coal-fired power generation technology and coal consumption for units will reach world advanced levels. The opinion points out that by 2020, the productivity of the coal industry will increase substantially, and resources will be appropriately developed. The degree of mechanization of coal mining in the country will reach more than 85%, and the degree of mechanization of excavation will reach more than 62%; the safety production situation in the coal mining area will turn for the better; The mortality rate has dropped to below 0.15; the utilization rate of resource development has increased significantly; the recycling system for resources has been further improved; the ecological environment has been significantly improved; the development of green mines has achieved positive results; and significant progress has been made in the construction of resource-saving and environment-friendly ecologically-civilized mining areas. The level of clean and efficient use of coal has been significantly improved. Coal-fired power generation technology and coal consumption per unit have reached the world's advanced level. The proportion of coal consumed in coal has increased to over 60%; the average operating efficiency of coal-fired industrial boilers has increased by 7 percentage points over 2013. The energy efficiency of coal conversion has increased by more than 2% on the basis of 2013, and the research on the development and comprehensive utilization of low-grade coal resources has made positive progress. The new coal chemical industry has achieved high-efficiency, environmental protection, and low-cost development; it has achieved high resource utilization and safety. Safeguards, good economic returns, less environmental pollution and sustainable development goals. China has focused on building 14 large-scale coal bases such as Shendong with abundant resource reserves, good mining conditions, and high development potential, and optimized the layout of coal production and development. By 2020, the coal production capacity of large-scale coal bases will account for about 95% of the country's total production capacity; the proportion of coal in primary energy consumption will be controlled within 62%. The opinion puts forward that with the focus on building large-scale modern coal mines, upgrading existing large and medium-sized coal mines, and eliminating outdated production capacity, we will comprehensively upgrade our production technology and safety guarantee capabilities. By 2020, the recovery rates for thick and extra-thick coal seams, medium-thick coal seams, and thin coal seams will reach 70%, 85%, and 90%, respectively; encouragement will be applied to “three-one-ups (under buildings, railways, and water bodies) under pressure. Water body) "Coal resources, coal pillars and corner coal residue mining. Opinions request scientific utilization of by-products such as mine water, coal gangue, coal slime, fly ash, comprehensive development and utilization of coal resources, and vigorously promote the remanufacturing of mining machinery, build a coal-based recycling economy industrial chain, and increase product added value and resources. Comprehensive utilization. By 2020, the comprehensive utilization ratio of coal gangue shall not be less than 75%; in the water-shortage mining areas, general water resources mining areas, and water-rich mining areas, the mine water or open pit mine water utilization rates shall be no less than 95% and 80% respectively. 75%; The rate of stable collapse of coal mines has reached 80%, and the reclamation rate of waste dumps and open pit mines has reached more than 90%. Opinions require accelerating the development and utilization of coalbed gas (coal mine methane). The coal prospects implemented "first gas recovery and later coal mining" to speed up the construction of CBM industrial bases such as Qinshui Basin and the eastern margin of the Ordos Basin, and strengthen coal seams in Xinjiang, Liaoning, Heilongjiang, Henan, Sichuan, Guizhou, Yunnan and Gansu. Exploration of gas resources, exploration and development trials in Hebei, Jilin, Anhui, Jiangxi, and Hunan to promote the development of CBM industry. By 2020, the proven reserves of CBM will be 1 trillion cubic meters. Coalbed methane (coal mine methane) output is 40 billion cubic meters. Among them: 20 billion cubic meters of ground development, basically all use; underground extraction of 20 billion cubic meters, utilization of more than 60%. Suggestions are made to effectively improve the level of coal processing and conversion. Accelerate the transformation of coal from a single fuel to both raw materials and fuel. In accordance with the principles of water conservation, environmental protection, and high efficiency, we will continue to promote key technologies such as coal coking, gasification, coal liquefaction (including kerosene refining), coal-to-natural gas, and coal-to-olefin technologies to improve the efficiency of coal utilization and reduce system energy. Consumption, resource consumption and pollutant discharge to achieve cleaner production. Moderately develop modern coal chemical industry. In 2020, the demonstration of industrialization of modern coal chemical industry will achieve phased results, form a more complete independent technology and equipment system, and have the basis for carrying out higher levels of demonstration. Breakthroughs have been made in the key technologies of the low-grade coal grade upgrading and core technology, and the demonstration application at the million-ton level has been achieved.
