To be a good energy leader, coal industry needs green and efficient support

Recently, China Shenhua, the world's largest coal listed company, announced its performance in 2018: the company achieved revenue of 264.1 billion yuan and net profit of 43.9 billion yuan. In the company's revenue composition, coal business is still the most important revenue, reaching 205.191 billion yuan, accounting for 77% of the total revenue. Among its coal mines, Shendong Mining Area is the most famous, while in Shendong Mining Area, Bulianta Coal Mine, the largest single-well coal mine in the world, has an annual output of 28 million tons. Recently, in Bulianta Coal Mine in Ijinholuo Banner, Ordos City, Inner Mongolia, the reporter saw amazing underground inclined shaft with depth of 200 meters and length of more than 10 kilometers, the world's first 8-meter high and heavy fully mechanized mining face, intelligent mine management system and the world's highest safety level, all representing the highest level of development source of China's coal mining and coal industry.

As the leader of energy industry in China, how can coal industry find the way of scientific development in the new era? With the rapid development of the national economy and the world energy market, it has become the only way to ensure the development of the coal industry to scientifically understand the current situation of development, innovate the development technology of the industry and expand the chain of industrial development.

The 14th International Coal and Energy Industry Exposition in Ordos and the National Conference on Green Coal Mining and Scientific and Technological Innovation and Development in 2019 will be held recently in Ordos, the "Grassland Coal Capital". Dozens of academicians and experts'sparks of thought collided, once again making coal and the national energy and chemical industry "Golden Triangle" (eastern Ningxia, northern Shaanxi, Ordos) a hot topic of social discussion.

"In order to make an industry develop healthily, we must first have a comprehensive, objective and in-depth understanding of the industry. Coal plays an important role in China's energy structure. It will still be the largest energy variety for a long time to come. Coal industry is likely to face the long-term trend of total volume decline. It is necessary to put more emphasis on high-quality development, continue to improve the structural adjustment of supply side, and constantly strengthen the green, clean and efficient level of coal utilization. Zhou Dadi, executive vice chairman of the China Energy Council and researcher of the Energy Research Institute of the National Development and Reform Commission, told Sci-tech Daily. In 2018, coal accounted for less than 60% of China's energy consumption for the first time, but still ranked first in 58% of all kinds of energy. In other words, coal is still the most important resource in China's energy consumption. However, this understanding is far from enough to guide the healthy development of the coal industry. Zhou Dadi's "high-quality development" and "green, clean and efficient" may be the key words for the development of the coal industry. What further considerations do we need to make in order to truly achieve high-quality development of the coal industry? He Dingchao, deputy director of the research center of the State Administration of Work Safety Supervision and Administration, said: "Overall, we should have the following understanding: the current regulation mechanism of coal production capacity still needs to be improved, the contradiction between reverse distribution of coal production and consumption is more prominent, the industrial structure of coal needs to be further adjusted, and the level of green development and utilization of coal needs to be improved." Statistical data show that in 2017, the coal output of Shanxi, Shanxi, Inner Mongolia and the new four provinces (regions) accounted for 72% of the country, while the coal consumption of Beijing, Tianjin, Hebei, Northeast, East China and South-central China accounted for 61% of the country; in the same year, there were 6 enterprises with a total coal output of over 100 million tons in China, accounting for 34.7% of the country's total output, and there were 3209 coal mines with a capacity of only 500 million tons in the country with a total output of less than 300,000 tons. The contradiction between the reverse distribution of production and consumption and the relative backwardness of industrial structure can be seen.

"In addition, the lagging application and popularization of technology such as historical debt of environmental protection and green mining in coal mines is also an urgent problem for us to solve in order to promote the high-quality development of coal industry." He Dingchao said.

Coal mining and selling is no longer industrial connotation

In the Ijinholuo Banner of Ordos City enriched in coal mine, Shengyuan Water Company can turn 230,000 tons of dredged water (sewage from coal mine production process) into clean water that feeds back urban ecology every day; The coal direct liquefaction technology production line of Ordos Coal Oil Branch of National Energy Group relies on high-quality oil products to laugh at Aoquan. The Ball. Mining coal and selling coal is not the connotation of coal industry, and the industry transformation under the guidance of technological innovation is the kingdom.

He Dingchao presented a statistic to reporters of Science and Technology Daily: from 2001 to 2017, the number of coal mine accidents and deaths in China dropped from 3082 in 2001 to 5670, respectively, to 219 and 375 in 2017. This qualitative change is not only due to the improvement of safety management consciousness and system, but also closely related to technological innovation. For example, the high-tech integrated mining face of Bulianta Coal Mine of Shendong Coal Group is a model.

What about the environmental pollution caused by coal mine production and coal chemical enterprises? What if the energy conversion rate of coal is not high? Where does the safe production technology of coal mine come from? How to realize the efficient, comprehensive and clean utilization of coal? Throughout the whole coal industry and coal chemical industry, to achieve sustainable development, innovation is the only way. In the process of rapid development of coal industry in Inner Mongolia, local economic experts put forward the theory of "realizing ecologization of technological innovation in coal industry". According to this theory, it is an inevitable trend for the coal industry to be ecologized, and the ecologization of technological innovation is the only way to realize the ecologization of the coal industry, so technological innovation should be integrated into every link of the coal industry.
