Factors affecting respirable dust generation from longwall roof supports. Information circular/1985

Technical Report ·
OSTI ID:6160786
; ;

The Bureau of Mines conducted a survey of eight shearer longwall operations to identify factors that affect respirable dust generation from longwall roof supports. The longwalls surveyed were in coal seams located in different geographic regions of the United States. Data were collected on mining (geologic) conditions, support design, operational characteristics, and amount of respirable dust generated from roof supports. Several practices are currently employed to effectively control roof support dust.
