The coal production process is complex. Coal production is generally divided into tunneling, mining, underground transportation, ventilation, drainage, shafts, equipment maintenance, screening and processing, and other production processes. Open-pit mine production is generally divided into stripping, dumping, transportation, line maintenance, equipment maintenance, drainage, screening and processing, and other production processes. Coal production is classified as hazardous operations. Production conditions change greatly, and are often threatened by underground natural disasters such as groundwater, fire, gas, coal dust, ground temperature, and ground pressure, and various safety accidents are prone to occur.

Coal mining, transportation, and coal washing processes are highly streamlined and mechanized. The process includes various large and complex machines such as coal shearers, belt conveyors, crushers, screening machines, etc. The working conditions are harsh and complex, and there are many transmission components (motors, gear box, roller), once damaged, it will directly lead to production interruption. The annual aging of coal mine production equipment has led to an increase in equipment maintenance costs.

According to the production characteristics of coal mining enterprises, Freqx has formulated a set of targeted solutions, which can promote the intelligent upgrade of coal mining enterprises, ensure the safety of equipment and personnel, and keep the efficient operation of production lines.
