Dust-control for thick-seam wall mines.

Abstract

This report describes research project COL 807 which was formulated to find ways of keeping down the dust in thick-seam wall operations to concentration levels of less than 5 mg/m3 and to minimize the dust exposure of workers while maintaining adequate ventilation conditions along the wall face. A directive of the South African Department of Minerals and Energy (DME, 1997) required the dust concentration level to be reduced below 5 mg/m3 at the operator’s position.
