underground coal mine dewatering systems
Underground Mining Transportation Haulage Systems
Conveyor systems have come into common use in coal mines during the past decade. As this is written, belt conveyors are beginning to make their appearance in metal mines as a part of the underground transportation system, and an increasing number probably will be installed during the next few years.

The groundwater system and possible effects of ...
The groundwater system was studied in the Trail Mountain area in order to provide hydrologic information needed to assess the hydrologic effects of underground coal mining. Well testing and spring data indicate that water occurs in several aquifers. The coalbearing BlackhawkStar Point aquifer is regional in nature and is the source of most water in underground mines in the region.

Conveyor Products | Brain Industries (International) Pty Ltd
Our underground mine dewatering equipment eliminates excess water, particularly where it causes problems on steep drift conveyor belts or in underground storage bins. Our systems also remove solids from the water, so it can be handled by the mine's regular water pumpout system without damage to pumps or pipelines.
