Coal is an important basic energy. Since the 18th National Congress of the Communist Party of China, China's coal enterprises have actively responded to the challenges brought about by the new normal of economic development, especially the pace of resolving excess capacity, promoting the balance of supply and demand in the coal market, and striving to achieve the development of the industry. Under the guidance of the new development concept, coal enterprises have accelerated their exploration in the field of clean and efficient use of coal. They have left the impression of “silly and dark†and accelerated the realization of “black†and “green†and traditional energy. The transition to clean energy has taken a powerful step toward transformation and development. In March 2017, Shaanxi Yanchang Group's syngas-to-ethanol industry demonstration project was successfully put into operation, and coal clean utilization was further broken.

Coal enterprises that once had "rich oils" have fallen into a bitter situation, and the phenomenon of slowing, reducing and paying wages has increased significantly. Behind the rapid economic situation of coal, it is closely related to the rapid expansion of China's coal production capacity in recent years. According to the analysis of the National Statistical Yearbook, between 2006 and 2015, the total investment in fixed assets of the coal mining and selection industry in the country was 3.67 trillion yuan, the newly added coal production capacity was 3.167 billion tons/year, and the coal production capacity under construction was 1.36 billion tons/year. The rapid growth of investment in the coal industry has greatly increased the supply capacity of the domestic coal market. However, with the slowdown in consumer demand in the coal market, the problem of overcapacity in coal is prominent, leading to a cliff-like decline in coal prices, which has swallowed corporate profits. Even some coal mines with good coal seam conditions, advanced mining technology and better benefits are on the verge. Loss or loss. In order to further promote the healthy development of the coal industry, in accordance with the decision-making arrangements of the Party Central Committee and the State Council, the National Development and Reform Commission, the National Energy Administration, the State Bureau of Coal Supervision and other relevant departments have successively studied and introduced a series of policy measures to help the coal industry resolve excess capacity and achieve It has played an important role in promoting the development of the disaster and the process of transformation and upgrading. In particular, with the advancement of structural reforms on the supply side, coal de-capacity work continued to advance and achieved positive results. With the continuous expansion of coal production capacity, the supply and demand of the coal market has gradually improved, the quality of economic operations has stabilized and rebounded, and the loss situation of the whole industry has been significantly improved. “Since this year, the coal economy has been running smoothly, which is related to the overall stability of the macroeconomic operation, and is also the result of the coal industry continuing to promote structural reforms on the supply side,†said Yue Fubin, president of the China Coal Economic Research Institute. Significant improvement in industrial structure Since 2012, China's coal industry has experienced the baptism of the industry's “long winterâ€. Although this market situation has caused many coal enterprises to be in trouble, the company has also gained a deeper understanding of the hazards of overcapacity and created favorable conditions for the smooth progress of production capacity. Since last year, in the process of promoting supply-side structural reform, the relevant state departments have actively guided coal enterprises to speed up the withdrawal of backward production capacity, and at the same time, through special actions such as clean-up of illegal construction projects, rectifying the order of the coal market and promoting the gradual improvement of the coal industry structure. . The data shows that in 2016, China has withdrawn more than 2,000 coal mines with depleted resources, long-term losses, and poor safety base. In addition to the need to protect people's livelihood, the rest of the projects have been suspended and the number of coal mines nationwide has dropped below 8,000. With the exit of a large number of backward production capacity and illegal and illegal production capacity, the pace of coal structure adjustment has accelerated. The layout of coal production and development has been continuously optimized, and large coal bases have become the mainstay of coal supply. In 2016, 14 large coal production bases accounted for 92.7% of the country's total; the country's coal production exceeded 100 million tons of provinces and autonomous regions, with a total output of 2.86 billion tons, accounting for 82.9% of the country's total output. Large modern coal mines have also become the main force of coal production in the country. By the end of 2016, the number of large-scale modern coal mines with an annual output of 1.2 million tons and above has increased by about 700 compared with 2005, and the output has accounted for more than 75% of the country. Among them, 59 large-scale modern coal mines with an annual output of 10 million tons have been built. The total production capacity is more than 800 million tons. Under the guidance of the state-driven policies on mergers and acquisitions, especially in the major coal-producing provinces and local governments, large coal enterprise groups have grown rapidly and industrial concentration has increased significantly. In 2016, the top four coal enterprises such as Shenhua Group, China Coal Energy Group, Shandong Energy Group and Shaanxi Coal Chemical Industry Group produced 821 million tons, accounting for 23.8% of the country; the top 8 enterprises produced 1.22 billion tons, accounting for 35.5 percent of the country. %, an increase of 12.2 percentage points over the previous year. Shenhua Group, China Coal Energy Group, Shandong Energy Group, Shaanxi Coal Chemical Industry Group, Tongmei Group, Yankuang Group entered 6 “annual production of 100 million tons of clubsâ€, and the number of 50 million tons of enterprises increased to 17 with a production of 18.2. 100 million tons, accounting for 52.8% of the country. Wang Xianzheng, president of China Coal Industry Association, said that with the advancement of coal industry structure adjustment, the industrial concentration has been greatly improved. Based on coal, the coordinated development pattern of coal-fired power, coal steel, coking, building materials, storage and transportation, finance and other related industries has begun. The formation, the synergy of coal production and marketing, new industries, new business and other innovative development models continue to emerge, and the vitality of coal economic development has been significantly enhanced. Significant green development Every time the smog strikes, the coal will always be referred to as "the thousands of people." With the tightening of environmental protection on the development of the coal industry, accelerating the realization of green development has become the only choice for the coal industry. In the face of new challenges, we must vigorously promote the clean and efficient use of coal, so that energy production and consumption will move toward clean and low carbon. In order to promote the clean and efficient use of coal, China's coal enterprises have carried out many useful explorations. In terms of green mining, in 2016, the national coal mine raw coal selection capacity was 2.6 billion tons, and the raw coal enrollment rate was 68.9%, an increase of 12.9 percentage points over 2012. The green mining technology based on coal mine water conservation and filling mining has been widely promoted. The resource utilization rate of mine water and coal gangue has been increased year by year. The comprehensive utilization rate of coal gangue and land reclamation rate have reached 64.2% and 48%, respectively. Compared with 2012, they increased by 1.7 and 6 percentage points respectively; the comprehensive energy consumption and production power consumption of raw coal production in large and medium-sized coal mines decreased by 30.9% and 28.2% respectively. A number of circular economy industrial parks such as Coal Tashan and Shenhua Ningdong have been built. Shenhua Shendong is committed to building a “three-phase, three-circle†ecosystem. The ecological management area of ​​the mining area is 256 square kilometers, which is 1.4 times of the mining disturbance area. The vegetation coverage rate has increased from 10% in the initial stage of development to more than 60% at present. The development of mining resources and the coordinated development of the ecological environment. In terms of clean coal utilization, in the past five years, the coal industry has done a lot of work around the clean utilization of 700 million tons of loose coal per year, and achieved results. The high-efficiency pulverized coal boiler technology with China's independent intellectual property rights has been widely promoted. The boiler fuel burnout rate is 98%, which is 28% higher than that of ordinary coal-fired boilers. The pollution emission indicators such as soot and SO2 are equivalent to natural gas boiler standards. On the basis of demonstrations in more than 10 provinces and regions such as Inner Mongolia, Shandong and Gansu, industrialization has been rapidly realized. In terms of coal-fired power generation, the demonstration project for ultra-low emission technology transformation of coal-fired power plants represented by Shenhua Group and Zhejiang Energy Group was successful. In addition, modern coal chemical industry has achieved development from demonstration to industrialization. A number of breakthroughs have been made in the key technologies of modern coal chemical industry and equipment development with direct intellectual liquefaction of coal, indirect liquefaction of coal, coal to olefins, coal gasification, and coal-to-glycol. The development of modern coal chemical industry has promoted the jump of coal from the low end to the high end of the value chain and expanded the space for coal consumption. In the future, the coal industry will continue to rely on scientific and technological progress to build a modern industrial system of “material closed loop, energy gradient utilization, economic and ecological harmony†to promote clean and efficient coal development and green low-carbon utilization.
