China is a big country with big coal production, and it is also a big consumer country with coal accounting for more than 70% of energy. During the “Eleventh Five-Year Plan†period, 13 large coal bases will be established. The mining mechanization of large coal mines must reach 95% or more, and the medium-sized coal mines must reach 80% or more. Safe and efficient coal mines have to reach 380, and their output accounts for 45% of the national total. This requires a large amount of high-quality and highly efficient equipment for the production of mining machinery. However, the technological level of these equipment in China is relatively backward. First, large-scale extraction equipment with an annual output of more than 8 million tons mostly depends on imports. Most of the large-scale coal mining equipment is from Germany and the United States. Imports from other countries are expensive and inconvenient for maintenance. The second is the manufacturing level and capability of China's coal machinery companies, and it is still difficult to meet the demand for coal mines with a capacity of 10 million tons. The production capacity of foreign coal mining equipment has reached more than 3,000t/n, and the coal mining face can achieve an annual output of 8 million to 10 million tons, and there has been a highly efficient and intensive production of a mining area and a production line. These devices are basically monopolized by German and American companies. Domestic equipment is still difficult to reach this level. Third, mining machinery manufacturing is still lagging behind mechanical engineering such as cranes and cranes. Fourth, product structure is unbalanced. On the one hand, the market demand for large-scale mining machinery and equipment can not be produced. On the one hand, low-end products and accessories have excess capacity. At present, China's coal market has an annual demand of about 50 billion yuan, but its production capacity has reached 150 billion yuan.
In view of the gaps and problems in China's coal equipment manufacturing, China needs to vigorously support the development of coal mining and mining manufacturing. To formulate special support policies, the “Several Opinions of the State Council on Accelerating the Revitalization of the Equipment Manufacturing Industry†has already proposed specific measures for the development of large-scale mining equipment for coal mines. Second, we must revitalize the equipment manufacturing industry and develop the coal machinery industry, and put it into special important positions to grasp and implement. For example, Shanxi has formulated the “Opinions on the Implementation of the Revitalization of Shanxi's Equipment Manufacturing Industryâ€, which will provide 500 million yuan from the finance every year for support. . It is necessary to support such coal mining machine companies. At present, Taiyuan is investing in the trial production of the largest domestic 2500 shearer.
We are convinced that Taiyuan will become the backbone enterprise of coal machinery manufacturing and create brand products.
New breakthroughs in mining machinery manufacturing
The 1800 coal mining machine of the Taikoo Mine hits the latest record of monthly coal production in the country and has reached the advanced level of similar foreign models. This is a new breakthrough in the field of China's mining machinery manufacturing and marks the gradual substitution of China's mining machinery and equipment.
