The solution for gas transmission and use in mining industry

Mining environment is harsh, the air compressor needs to run continuously for a long time under the conditions of dusty, high humidity, big temperature change, and even some corrosive gases. Therefore, air compressors for mining must have high reliability and provide stable air power.

Industry information

Mining development with gas supply, screw air compressor applications are specified as follows

Rock drilling operation

In the early stages of mining, it is necessary to drill holes on the surface of rocks, and rock drills require compressed air to drive them. For example, before mining ore in an open-pit mine, a series of boreholes need to be drilled on the surface of the ore rock using a rock drill to place explosives for blasting. Rock drills are also required to drill holes in underground mining tunnels, mining faces, and other locations, with air compressors providing stable power support.

Pneumatic tool operation

Various pneumatic tools such as pneumatic wrenches, pneumatic screwdrivers, etc. are used in mining maintenance and some small-scale construction. These pneumatic tools rely on compressed air provided by an air compressor as power. For example, when conducting daily maintenance on equipment in underground mines, using pneumatic wrenches to disassemble and install bolts of large equipment is more efficient than manual wrenches, and air compressors provide power support for pneumatic wrenches.

Cleaning of ore loading and transportation equipment

During the mining process, ore loading equipment (such as loaders, electric shovels, etc.) and transportation equipment (such as mining trucks, mining cars, etc.) will be contaminated with a large amount of dust and ore debris. By blowing with high-pressure air, the dust and debris on the surface of the equipment are cleaned up, which facilitates inspection and maintenance of the equipment and can also extend its service life.

Desulfurization and oxidation process

Pain point background

The high energy consumption of traditional air compressors and the mismatch in operating efficiency lead to a large amount of energy being wasted, and the monitoring system is relatively simple, unable to monitor the operating status and key parameters of

Pain Point 1

Traditional air compressors usually operate according to fixed parameters, making it difficult to adjust the output power in real time according to the actual air consumption.

Pain Point 2

Traditional air compressors rely on loading and unloading to control the air output, in the unloading process, although the compressor is no longer output compressed air, but the motor is still running, this part of the no-load energy consumption accounted for a small percentage, increasing the overall energy costs of the mine.

Pain Point 3

The monitoring system of traditional air compressors is relatively simple, unable to monitor the operating status and key parameters of the equipment in real time, and when the equipment is abnormal, no timely warning can be issued.
