port equipment underground, and its volume of patent applications in the art first; while boring machine mechanical patent application no. Ranked fourth in the Sandvik Group is a leader in many areas of expertise have advanced product, its patent applications focused on mining machinery and excavating machinery, but mostly for devices assistive devices, without the whole aspect of patent applications. DBT in mining equipment, underground transport facilities in these two areas of patent applications volume ranked first. DBT underground conveyor patent applications are scraper conveyor. For JOY company, although a small number of patent applications, but are fundamental patents in the field, especially in the field of high-end shearer, shearers in improving machine reliability, intelligent and has great advantages. At present, the Chinese market has initially formed a relatively complete product chain or have competitive products, coal is expected to become the industry leader in the six Mining Machinery Holdings: Coal Energy, IMM, Sany Heavy Equipment, space technology, heavy Group, Zhengzhou Coal Mining Machinery. In addition to heavy group, the remaining part of the five largest coal enterprises and leading enterprises in regional and market segments has landed capital markets. In the invention patent applications and ownership aspects, Sany Heavy Equipment, World Technology, Zhengzhou Coal Mining Machinery obviously at the forefront of its sustainable development has laid a good foundation. The applicants in China, China University of Mining beyond Sany Heavy, Zheng coal machine, space technology and other well-known Chinese coal machine manufacturing enterprises and ranks the first one, as a college applicant, its patented technology level, R & D direction, degree of industrialization should be cause for concern. From the patent application trend, in 2005 after the sudden increase in patent applications; patent applications from the field of view, rescue equipment, the largest amount of patent applications, and concentrated in recent years; from the applicant, the domestic enterprises showing a contending situation, and foreign patent applications entering China are very small. And other mining machinery differences in the safety equipment in the field, applicants universities, research institutions more enterprises are relatively small. Among them, China University of Mining and Henan Polytechnic University were ranked first and third.As Table 2 shows, China's major coal mining machinery enterprises involved in the field of safety equipment less, except SANYHE outside of the top 15 applicants in no major coal mining machinery enterprises. Figure 2 shows the safety equipment in the field of patent applications in China the proportion of various branches of technology, including rescue equipment, the largest amount of patent applications, but also domestic research hotspot in recent years.Table 3 shows the technical rescue equipment mining machinery branch of patent applications development, seen in recent years, rescue equipment, the technical branch of patent applications showed a rapid growth trend.
Development of technical difficulties and focus on each other to achieve win-win
Chinese coal mining machinery industry in order to break through the bottleneck of the development may be made by the current market and technological development of the good momentum and further efforts to increase R & D and patent applications, covering the Chinese market, and gradually to expand overseas.
From the field of mining machinery number of patent applications point of view, China's patent applicants in the global patent applications Zhuanshuai situation upstream. However, some branches of technology and key technology patents, mainly rests in the hands of foreign companies. Chinese enterprises are some of the key components, such as pumps, operated valves, controllers, cutter, reducer  hydraulic motors and other major still rely on imports. To break through the bottleneck of the development of Chinese enterprises should concentrate on solving some technical difficulties, through independent research and development, cooperative development, purchase patented technology and other means to continuously improve the product's overall level of technology. From the entire course of development of coal mining machinery industry, the international coal giant with mergers and acquisitions, the overall trend of expansion, to form a complete industrial chain. For example, DBT company, JOY consolidation throughmergers and acquisitions the company has become a large mining machinery group.Although some Chinese enterprises have already upgraded to group, forming a complete set of coal capacity, but most companies were specialized product range, unitary state, and between enterprises in certain product lines overlap each other, and thus become competitive state.Th
