China's coal industry as a whole has improved
RELEASE TIME: 2019-06-27

With the acceleration of the adjustment of coal structure, the improvement of scientific and technological innovation capacity, the improvement of clean and efficient utilization of coal, and the improvement of coal mine safety production, the overall situation of China's coal industry has undergone a huge transformation.

In terms of structural adjustment, the number of coal mines in China has decreased from more than 80,000 in the 1980s to about 8,000 at present, and the size of coal mines has increased from less than 30,000 tons per year to more than 500,000 tons per year. The proportion of large coal enterprises has been increasing, and the integration of coal with new technologies, industries and forms of business has been accelerated. A new pattern of coordinated development of diverse industries, including coal mining, electric power, coal chemical industry, building materials, new energy, modern logistics, e-commerce and financial services, has taken shape.

The industry's capacity for scientific and technological innovation has been significantly improved. According to the China coal industry association Wang Xianzheng, introduce our country coal resource development, prevention and control of major disasters in coal mine, coal efficiently convert important progress was made in basic theory research, such as large mine construction, special thick seam fully mechanized mining, coal ultra low emission power, high efficiency, new type pulverized coal industry boiler coal chemical technology reached the international leading level, the annual output of 2000 ton large open-air and yearly produces 1000 ton mine mining equipment, ecologically fragile area surface ecological protection key technology, key technology research for large diameter deep shaft built well made significant breakthrough, intelligent coal mining technology and equipment has reached the international advanced level. "Shenhua one million tons of direct coal liquefaction project is the world's first set of demonstration projects and has achieved long-term stable operation; Shenhua million tons, yankuang million tons and shenhualing coal 4 million tons of indirect coal liquefaction projects have been completed and put into production; Xinjiang yili, Inner Mongolia keqi coal-to-gas project completed and put into production...... "A large number of modern coal chemical demonstration projects, represented by direct liquefaction of coal, indirect liquefaction of coal, coal-to-alkene, coal-to-gas and coal-to-ethylene glycol, have achieved success, promoting the transformation of coal from fuel to fuel and raw materials, and from project demonstration stage to industrialization," wang said.

Clean and efficient use of coal has been greatly improved. Shenhua guohuateshan power plant, zhoushan power plant, huaneng yuhuan power plant, zhejiang energy jiaxing power plant and other high-standard coal-fired power generation demonstration projects have been completed, with emissions of soot, sulfur dioxide and nitrogen oxides meeting or falling below the standards of gas-fired power plants. By the end of 2016, China's coal-fired power plants had completed transformation of 320 million kilowatts of ultra-low-emission technologies, accounting for one-third of the country's total installed coal-fired power plants. The burning rate of high-efficiency pulverized coal boilers with independent intellectual property rights is 28 percentage points higher than that of ordinary coal boilers, and the main pollution emission index is lower than the national standard. Yankuang group and other enterprises have developed clean bulk coal burning furnace products, and the rapid development of power, industrial boilers and civil bulk coal cleaning technology, which has promoted the clean and efficient utilization of coal in China.

At the same time, China has established the national coal mine safety supervision system and formulated the coal mine safety responsibility system. The safety investment in the coal industry has been continuously increased, the long-term mechanism for coal mine safety production has been continuously improved, and the coal mine safety guarantee capacity has been continuously improved. The situation of coal mine safety production in China has been significantly improved.
