ABSTRACT:
Boreholes are drilled at an angle from gate roads to the working face in a longwall mining operation, and air is exhausted from the working face area through the boreholes. Additional boreholes, parallel to the first boreholes, are drilled from the gate roads into the longwall pillar, and as the face moves through the pillar it intersects the additional boreholes, and dust-laden air is exhausted through the additional boreholes.
