After decades of efforts, the mining machinery industry in China has got vigorous development, but compared with foreign industry, there is still a considerable gap in developing level, especially in the open-air mining equipment and underground transport equipment; on the mining machinery products, there is a certain gap in manufacturing quality, appearance, reliability, longevity, design levels and test methods with the advanced industrial countries; Having join the WTO, in order to accelerate the development of basic industries, we must accelerate the development of mining machinery and research speed.

In recent years, through introducing products and technologies, or cooperating with the well-known foreign manufacturers, the mining machinery industry in China has accelerated products upgrading, made substantial progress, enhanced and improved the structure, performance and appearance of traditional products, upgraded the level of manufacturing technology. 

However, with social progress and scientific and technological development, life safety and property security issues has been paid more and more attention, machinery safety has been gradually formed an independent discipline, and accepted by the community. First of all, if danger hidden in work overload or high-speed environment cannot be promptly found, it could lead to fatality such as winches damage, wire rope breaking, belt conveyor burning; Second, with the development of mining industry mechanization, the possibility of operators and people around being injured by potential safety hazard has also been increased. Safety accidents caused by the mine machinery and equipment hazards would lead to huge losses for coal companies, and also makes serious threat to the safety of coal mining machinery employees, therefore, safety issues in mining machinery must be paid great attention.
