Around 2013, the coal mine environment was good, some users actively tried emulsion motors, and some users still continue to buy them. Because the underground operation of coal mine has very high requirements for safety and explosion prevention, especially for electrical equipment, once an explosion accident occurs, the damage rate is very high, which will affect the normal operation of coal mine. In recent years, China's coal production structure has been optimized, the total number of coal mines has been decreasing, and the number of large coal mines has been increasing. In 2021, the raw coal output of Coal Enterprises above Designated Size nationwide will reach 4.07 billion tons, a year-on-year increase of 4.7%; It was 96million tons more than the original year of the country's highest raw coal output (2013), a record high. By the end of 2021, the number of coal mines in China has been reduced to less than 4500, and the output of large coal mines with an annual output of more than 1.2 million tons accounts for about 85% of the country.
Through CMRC market research, it is found that there is a corresponding relationship between coal mine capacity and equipment stock. In addition, most of the coal mines are group type, and there are many mines under them. Many non fixed equipment can be dispatched on different mines. The equipment and a single mine are not point-to-point.
According to China's "fourteenth five year plan", coal production is concentrated in resource rich areas, and the policy tendencies of provinces and cities are different. In Shanxi, Shaanxi, Inner Mongolia, Guizhou, Henan and other provinces and cities with rich resources, policy planning focuses on developing high-quality coal production capacity and promoting intelligent coal mining; The policies of Zhejiang, Jiangsu and other regions focus on structural transformation and green development.
Around 2013, the coal mine environment was good, some users actively tried emulsion motors, and some users still continue to buy them. Because the underground operation of coal mine has very high requirements for safety and explosion prevention, especially for electrical equipment, once an explosion accident occurs, the damage rate is very high, which will affect the normal operation of coal mine. The working medium of emulsion motor is high water-based emulsion, which is a non combustible liquid; The non-circular planetary gear mechanism has compact structure, large torque, can adapt to high-pressure environment, strong bearing capacity and good anti pollution ability, so it is suitable for operation in flammable and explosive environment.
