Using advanced algorithms, Process Intelligence extracts and reads the time stamps used to record specific events along your processes. The software then visually models these time stamps in such a way that you can instantly identify deviations from the ideal process flow—to find the root cause of a problem that may be costing your business money.
Long wall mining is a mostly automated process whereby long-wall mining machines are used to extract blocks of deposits as wide as the face of the equipment, and potentially kilometers long. Cutters are then used to cut the deposits from the face of the equipment. Room and pillar mining is a common underground mining method for mining oil shale.
