USIBELLI COAL MINE PHOTOS
Bill Brophy (UCM) demonstrates to AIPG field trip participants how incidental ground water that is collected from the coal seams is treated with a flocculent to cause sediment to settle to the bottom of holding ponds for initial removal of parti- cles. The resulting bottom sediment in the holding ponds is periodically removed as needed to maintain the pond’s holding capacity.
The AIPG field trip group poses in front of a UCM dump truck, and is dwarfed by the tires. And you think you pay a lot for new tires… these run into four-figures each.
Very large equipment is required to move material effi- ciently for mining in general and at the Usibelli mine. A bulldozer with its load of coal is shown here. Photo by Chris Arend.
The shovel capacity of a loader is demonstrated by the people for scale. Photo by Chris Arend.
The mining machinery are impressive at moving large volumes of material, as shown here by a typical loader and dump truck in
action. Photo by Chris Arend.
