"The current supply of coal is tight, and it is facing the danger of power and heating restrictions at any time." Affected by the epidemic, coal burning "red lights" in many places. Whether it is the need for epidemic prevention or the need for stability, coal mines are urgently required to resume work and production in an orderly manner.
From safe production to epidemic prevention and control, the coal industry is also facing unprecedented difficulties. It is worth noting that coal production itself is a labor-intensive operation. Not only does it share underground ventilation systems, but underground vehicles such as cages are also small in space and relatively closed. The gathering of people greatly increases the risk of virus transmission. In addition, some mines are unable to resume production and work due to a large number of personnel who cannot return to work in time, resulting in a shortage of manpower.

According to Zhao Yixin, Dean of the Institute of Science and Technology of China University of Mining and Technology (Beijing), the resumption of production and work under the epidemic prevention and control stage is also a window period for coal mine planning and development and optimizing management. It is time to plan and deploy intelligent mine upgrade and transformation plans.
The conveying system, one of the six major coal production systems, has been upgraded through the drive technology of the intelligent permanent magnet direct drive drum technology, laying the foundation for the conveying system to achieve "unattended" and "smart coal flow". Since the “new crown” epidemic, smart permanent magnet direct-drive drums have played a strong role in the production of major energy companies, and are continuously transporting coal to the ground.

Jiangsu Jiaxuan Intelligent Industrial Technology Co., Ltd. is a high-tech enterprise in Jiangsu Province. It mainly develops and manufactures permanent magnet high-speed motors, permanent magnet direct drive motors, and permanent magnet direct drive electric drums. At present, it has the world's first 315KW explosion-proof certification and has obtained 106 national safety standard certifications. The product has been selected into the national energy-saving catalog. The actual mine single machine safely runs for more than 20,000 hours.
