Dust-control studies using scale models of coal mine entries and mining machines. Report of investigations

Technical Report ·
OSTI ID:7109133
Three scale models of coal mine entries and mining machines were constructed and used to study the effects of ventilation parameters on dust concentrations where mining personnel would be working. A 1/5 scale model of a coal mine entry with a drum type continuous mining machine and a 1/6 scale model of an entry with a twin borer type machine were used as well as a 1/5 scale model of a longwall face with a double drum shearer. Methane was used as a tracer gas to simulate respirable dust in the models.
