Longwall mining is extraordinarily efficient. Rather than drilling through the ore deposit, a longwall machine cuts across it, shaving off slices up to 600 feet (182 meters) long. Those slices drop directly onto a continuously moving conveyor, which carries it to a haulage shaft that lifts it out of the mine

•To define the main functions of a shaft, a Process Flow Diagram (PFD) is required. The PFD, in the case of mine shafts, is really a mass flow diagram detailing what is required of the shaft. • After all functions have been identified and a mass flow completed, then the size of the shaft can be determined. Once the PFD has been completed, then the Design Engineer can proceed with the
