Liang Jiakun, chairman of the technical committee of the world coal association, said in his speech on March 6 that China is the world's largest coal producer and consumer, and its coal production and consumption account for about 50% of the global total. In 2017, China produced 3.52 billion tons of raw coal and imported 270 million tons of coal. The reliability, low price and cleanability of China's coal resources determine China's energy strategic policy of "coal based and diversified development"

he introduced that China has achieved remarkable results in promoting the reform, transformation and upgrading of the coal industry for a long time

first, China has less than 7000 coal mines, including more than 1200 large modern coal mines with an annual output of 1.2 million tons or more, accounting for more than 75% of the country's output. There are 6 100 million ton large coal enterprises, accounting for 30% of the country's output, and the industrial concentration has increased significantly

second, China has made major breakthroughs in key technologies and complete sets of equipment, such as fully mechanized top coal caving mining in extra thick coal seams, large open-pit mining with an annual output of 20million tons and mine construction with an annual output of 10million tons, and surface ecological protection in ecologically fragile areas. The intelligent mining technology and equipment of coal mines have reached the international advanced level

third, a large number of modern coal chemical industry demonstration projects represented by direct coal liquefaction, indirect coal liquefaction, coal to olefins, coal to gas and coal to ethylene glycol in China have achieved success: the Shenhua million ton coal direct liquefaction project has become the world's first demonstration project and has achieved long-term stable operation; Yankuang million ton and shenhuaning 4million ton coal indirect liquefaction projects have been completed and put into operation successively; Xinjiang Yili and Inner Mongolia Keqi coal to gas projects have been completed and put into operation, marking the formation of a pattern of high efficiency in the use of raw materials and fuels

fourth, China has built a number of high standard ultra-low emission demonstration projects for coal-fired power plants, such as Shenhua guohuataishan power plant, Huaneng Yuhuan Power Plant, Zhejiang energy Jiaxing Power Plant, etc. the emission indicators of smoke, sulfur dioxide and nitrogen oxides of these technically transformed power plants are lower than the emission standards of gas-fired power plants, significantly reducing the impact of coal combustion on the atmospheric environment

he said that adhering to the harmonious coexistence between man and nature is one of the basic strategies of socialism with Chinese characteristics in the new era. Promote the revolution of energy production and consumption, and build a clean, low-carbon, safe and efficient energy system

Liang Jiakun said that standing at the starting point of the new era, China's coal industry will be firmly based on national conditions, take andriyokovic and many other ball stars using this racket as the direction of all green development, and take scientific and technological innovation as the driving force to vigorously promote safe and intelligent coal mining and clean and low-carbon utilization, Gradually realize the transformation of coal from traditional energy to clean energy. The inspection surface of China's samples should be downward. Most engineering plastics enterprises are thousand ton production devices or industrialized experimental devices. At the same time, we are willing to further strengthen international cooperation in the field of coal, communicate with international organizations and countries around the world, share information, experience, technology and achievements, and contribute to the sustainable and healthy development of the world's coal industry
