A breath of fresh air

Copper miner, Kunming Fengjing Mining (Kunming), is using an Atlas Copco electric portable air compressor in its underground operations in Dongchuan Copper Mine Field


. Based in the Yunnan province in the west of China, the company has been operating in copper mining at Dongchuan Copper Mine Field for over 15 years. Throughout its existence the company has continually looked to improve its ways of working.

The copper reserves in the Dongchuan area are predicted to be over five million tons. Kunming is using the compressor for blasting and setting the copper ore free. The electric compressor is emission-free and the total cost of ownership is lower.

Since the mining takes place underground, any form of gas emissions can be detrimental to the health and working conditions of the miners. Moreover, the unit will keep working at high load for thousands of hours per year, so having a high efficiency and energy saving compressor is vital.

Equipment Management Director, Mr. He, is happy with the compressor’s results thus far. “The E-Air is really easy to use. The electric unit is a perfect match for our underground application and the protection of our workers is our first priority. The ventilation in this underground mine is poor, so with the use of this powerful electric compressor we avoid polluting gases.”
