In an effort to improve mine safety, a completely hydraulic transport system was designed to move coal from the mine face to the preparation plant. Mine production for the conventional haulage mine is 1.1 million tons of clean coal per year; the hydraulic haulage mine will produce over 1.6 million tons of clean coal per year. Two hydraulic systems based on commercially available equipment were designed. The surge feed hydraulic system allows the continuous miner to operate at peak efficiencies. The direct feed system requires the continuous miner to work at a slower, more uniform rate. Each of the hydraulic systems offers greater coal productivity and lower mine mouth coal costs.
