UrBC, Yekaterinburg, January 29, 2020. EVRAZ Holding launched a new, portable gas-drainage unit at Alardinskaya Mine, the company’s PR Department reports.

The new appliance is meant to reduce the gas emissions coming from the rock mass and to make underground mining safer. The unit can drain up to 400 m3 of gas from under the ground every minute.

‘This is the third gas-drainage facility installed at the mine. The unit is fitted with an up-to-date filtering system. Cyclone is used to filter the methane-air mixture from excess moisture, coal dust, and other contaminating particles. This ensures reliable equipment performance and reduces the impact the entire mining process makes on the environment,’ the company says.

The gas-drainage unit is also fitted with powerful rotary-type pumps, is fully automated, and runs on operation mode control equipment. The primary parameters to control for (the amounts of methane and oxygen and the temperature of the methane-air mixture) get displayed on the operator’s screen, which means any emergency can be promptly reacted to.
