Answering demands for dewatering solutions. ''s vertical plate pressure filter (VPA) has been developed to meet increasing demands for higher efficiency and automation in industrial and mining dewatering applications. The new VPA is a heavyduty machine suitable for metallic minerals, industrial minerals, and coal and tailings.

In practice, however, there is little or no experience of well dewatering of underground coal mines (except for shaft dewatering) that is available to be drawn upon, and the well dewatering systems that have been published are idealized and not necessarily compatible with field conditions.

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.
