Currently, China's coal industry in the rapid development at the same time, it appears a lot of worrying. These issues will affect the development of the coal industry in the future is in good health, and thus sustainable development of China's coal industry will also generate constraints.
1. Weak industrial base, short product life, reliability
Lag due to the development of China's basic technology, making the key components, bearings, seals, motors, electrical components, hydraulic components - compared with the international advanced level in the life and reliability are large gaps, it is difficult to meet the coal machine equipment high-performance, high-reliability needs of these problems caused by the poor reliability of the suite of products, short life.
2. Weak technological innovation capability
Most of China's coal production enterprises technology development center, dependent on scientific research institutes, independent development and innovation capacity of enterprises is weak, coal machine manufacturing company has not yet formed a virtuous circle of independent development, product development cycle is too long, the enterprise market rapid response capability, less investment in science and technology development, and a serious lack of professional and technical personnel.
3. Product technical standards lag behind
Our current coal product technical standards are generally lower than similar products on the international technical standards, some standards for many years before the amendments, has been unable to meet the development needs of existing products.
4. Coal mining equipment manufacturing industry overall competitiveness is still weak
Coal mining equipment manufacturing industry in China, the annual production of the total number of the largest in the world, but the strength is not strong, the lack of international competitiveness, can only rely on low-cost to participate in market competition; Technological innovation system is not formed, the capability of independent innovation is weak, there is no master new product development initiative; China's coal mining equipment manufacturing enterprises amounted to more than 800, but not a business to be among the top 500 in China, let alone the top 500 in the world.
5. The coal industry investment vigorous, coal machine capacity growing too fast
With the improved the stoker situation market, adding more and more manufacturers of coal mining equipment manufacturing, while the existing coal enterprises have technological transformation, new stoker Industrial Park, the formation of new businesses through joint reorganization, the coal machine rapid capacity growth.
6. The high-end products still rely on imports of low-end products of serious excess capacity
China's industrial base is weak, technological innovation ability and technical standards for products backward and many other factors, resulting in domestic large-scale mechanized mining mechanized excavation and the PREPARATION outfit reliability, automation, information technology master hysteresis, high-end products to be imported, the control technology of mine hoist control of a foreign company, a serious shortage of complete sets of technology and equipment for the small coal mining. On the other hand, a considerable number of coal production enterprises engaged in only some of the low level of technology imitation of simple products, inability to engage in the development of new products, resulting in a hydraulic support, such as low-end, small scraper conveyor, small belt conveyor accessories and mechanized face excess capacity, low product quality.
