Evaluation of a continuous miner half-curtain dust control system in a South African underground

摘要

The issues of public health and safety in themining industry have been dealt with around the worldthrough the intervention of governments. I 1997 theSouth African Department of Mineral and Energy sent outa directive to reduce the dust concentration level to< 5 mg/m3 at the operator's position for the samplingperiod. The reason for the difficulty with complianceare: long headings up to 35m, inherently high dustgeneration rates of coal, and the increased use of highlymechanized equipment. A project was formulated underSIMRAC auspices with the title of " undergroundmechanical environmental control" to address the dust problem.
