Contact usCOST CONTROLS AND EXPERTISE. Coal Operations. We deploy surface miners for the difficult applications – partings and thin seams. Partings that are deemed inseparable result in discarded or lower-quality coal. We expertly use surface miners to remove these partings, resulting in better coal delivered and increased recovery of the deposit.
