Abstract
This Bureau of Mines paper identifies guidelines for the optimum use of scrubbers on continuous mining machines. The guidelines are for maximum dust control with respect to quartz dust exposure of miner operators and shuttle car operators, while maintaining an output of more than 1,000 tons per unit shift. The optimum use of a continuous miner would be to mine coal for a 40- to 45-foot advance before place changing. The use of radio remote control can help achieve greater advance between lifts by locating the operator in fresh air during part of the mining cycle. The operator is also kept away from newly exposed roof which is not supported. A study by the Bureau of Mines indicates that a high output was achieved from a 50-in seam with a scrubber-mounted continuous miner and remote control. Research results in the use of a scrubber system with exhaust face ventilation are discussed. Bureau studies also indicate that a water-powered scrubber system can reduce the dust exposure of the miner operator without the noise and complexity of a fan-powered system. Results of laboratory and underground evaluation indicate the feasibility of such a system. Finally, attention has to be paid to good installation and maintenance of beltlines for increased productivity.
