Twelfth Five-Year Plan of the Coal Industry Inspires New Development of Coal Machinery Development

Coal has always been China's most important consumer energy, and its proportion in the primary energy consumption structure has remained at around 70%. Coal resources are still the most important consumer energy in China in the coming decades. This has laid the foundation for the development of the coal machinery industry.

"Twelfth Five-Year Plan" Development of Coal Machinery According to reports, the "Twelfth Five-Year Plan" of the coal industry has basically been finalized, and the "Twelfth Five-Year Plan" coal work will be clear "Four Groups, Large Bases, Large Mines, and Large Channels". The "big" principle, the continued promotion of mergers and reorganizations, and the development of large-scale enterprise groups are listed as key tasks. The goal is to increase the number of tens of millions of tons of companies from 5 to 10. In addition, increasing the utilization of CBM utilization and improving the localization level of coal mine equipment are also the key development directions in the “Twelfth Five-Year Plan”.

The “12th Five-Year Plan” focuses on the direction of development and continues to promote mergers and reorganizations. It is destined that the application of coal machinery will be more extensive. Mines that did not have the mechanized coal mining conditions can also use coal machines due to the expansion of scale, and the demand for coal machinery will increase. Big step up.

The overall development goals of the coal industry during the “12th Five-Year Plan” period: the development layout is clearly optimized, and resource allocation and exploration norms are in order; coal production is dominated by large-scale coal companies, large-scale coal bases, and large-scale modern coal mines, basically forming a stable supply pattern, and by 2015 In the year, 10 million tons and 10 50 million tons of extra-large coal enterprises are formed. According to estimates by the China Coal Economic Research Institute, this year's coal production capacity may be close to 3.5 billion tons, an increase of 1-2 billion tons compared with last year, and the coal production at the end of the "Twelfth Five-year Plan" should be more than 4 billion tons.

Coal planning has guided the national coal machinery demand. Large-scale coal enterprises, large-scale coal bases, and large-scale modern coal mines directly increase the urgent demand for the mechanization rate of the coal mining industry from aspects such as the scale of operation mode and the safety aspect, and the space for coal machinery in 3-5 years is extremely wide.

It is understood that during the “Eleventh Five-Year Plan” period, the national coal industry eliminated the outdated production capacity and achieved great results. A total of 9574 small coal mines were closed, and lagging production capacity was 530 million tons. However, there are still nearly 10,000 small coal mines in the country. At the end of the second five-year plan period, the number of small coal mines fell below 7,000, the mechanization degree of coal mining reached more than 55%, and the mechanization degree of excavation reached more than 80%.

The history of coal machinery development has undergone degeneration since the “5th Five-Year Plan”. Over the past 40 years, China’s coal mining mechanization has progressed from drilling and blasting shotguns, cutting coal-plowing machines, to the production of high-yield, high-efficiency, fully-mechanized mining mechanization. Coal mechanization technology and coal mining machinery and equipment have achieved remarkable results in all aspects.

According to statistics, China began to vigorously develop extractive mechanization in the 1970s. In 1974, 43 sets of mechanical and chemical recovery equipment were introduced. From 1976 to 1978, 38 sets were imported from the Soviet Union and Eastern Europe. After 1978, full-scale mining equipment was imported from Western Europe and Japan. With more than 100 sets, the production capacity of fully mechanized coal mining and comprehensive mining in key state-owned coal mines in China began to take shape. In 1984, 46 sets of full-mechanized mining equipment were purchased from Poland and the manufacturing technology of boring machines was imported from Austria, further accelerating the process of mining mechanization. At the same time as the introduction of equipment, China digests and absorbs advanced foreign technology and vigorously develops the research and development of domestically produced fully mechanized mining and fully-explored equipment. Statistics show that the degree of mechanization of coal mining in China has increased by 16.7 times in 2007 compared with 1978, and the localization rate of mechanical equipment has increased significantly. In addition to large-scale shearers and key components, the rest can be completely domesticated. To the direction of intelligence and high reliability. The number of high-yield, high-efficiency, safety-producing mines has increased significantly: in 1993, there were only 12 high-yield and high-efficiency safe production mines, and in 2008 it reached 268, an increase of 21.3 times. Especially in the past 10 years, the level of coal mining technology and equipment has been significantly improved. R&D has successfully applied the fully-mechanized top-coal caving mining technology for ultra-thick coal seams with a thickness of more than 10 m, the fully-mechanized mining technology with large mining height of 3.5-7.0 m thick, and the short-wall mechanized mining. As for technology, the working face parameters, equipment capabilities, and system reliability have been greatly improved, and a batch of mines with an annual output of 10 million tons have emerged, completely reversing the situation in which China's coal mining technology and equipment levels and production capacity requirements are not adapted.

After 40 years of development, our country's coal mining technology has gone through three stages: building a team, building a foundation, and technical research in the 1970s, and promoting the application in the 1980s. In the 1990s, we have achieved a high level of development. Coal mining has achieved innovative results; at the beginning of the 21st century, 10 million tons of fully mechanized coal mining face emerged, and roadway excavation and support technologies have steadily increased.

The future main attack integrated automation Our coal mines, especially the state-owned coal mining coal mechanization degree has basically universal three-machine support, many coal-fired machine companies have their own cutting-edge products: the largest power coal mining machine, automated unmanned mining equipment and other equipment have a strong strength , Such as heavy heavy coal machinery, Taikoo, China Coal Equipment, Shanhe Intelligent, Sanyi Heavy Equipment, Shenhua Group, Yongmei Group, Huainan Mining and Yankuang have adopted the world's advanced technology.

With more than 50 years of development, the world's fully-mechanized coal mining has become the main coal mining technology in advanced coal mining countries. In particular, the development of comprehensive automated coal mining technology with the core of information technology and mechatronics technology has made the coal industry undergo a profound The change will accelerate the transition from labor-intensive to technology-intensive. In mine mining, the production process centered on a large-scale fully mechanized coal mining face with an annual output of 10 million tons has fundamentally changed the appearance of mine production; the combination of artificial intelligence and expert consultation systems has opened up the intelligent integrated mechanized coal mining. way.

In recent years, China's mechanized coal production and degree have achieved rapid growth, the number of mining operations has decreased, yields have increased, and work efficiency has increased. The level of coal mining mechanization has been significantly improved. The development of mechanized coal mining mechanization equipment in China has experienced a process from scratch in the production of fully mechanized coal in state-owned key coal mines. The proportion of imported equipment has increased from introduction, digestion and introduction to improvement, and the proportion of imported equipment has been declining year by year. At present, domestic equipment has occupied a dominant position.

Industry experts believe that while China’s modern mining technology is developing rapidly, it is still necessary to continuously research and develop new technologies: the intelligent technology of high-intensity mining face equipment is subject to research and development, and the automatic control of coal machinery equipment is truly realized, and the working face will be unmanned. It is the main development direction; the comprehensive technology to improve the reliability of the complete equipment system of working face needs to be further developed; the coordinated mining technology of safety, environment and coal mining needs to be developed; the law of surrounding rock activity under high-intensity mining conditions needs further study.

The development of coal machinery requires a high-tech transformation of the coal industry from a technical perspective to achieve safety, efficiency, cleanliness, and sustainable development; and to optimize the structure from the institutional level and form large-scale enterprise groups. Looking forward to the next five years, the comprehensive automation of coal machinery is the main direction. Safety, efficiency, cleanliness, structural optimization and sustainable development are the development directions of the coal industry.
