    Boreholes 2–4 in. in diameter are drilled from the tailgate to a depth of 100–500 ft in the floor. The inclination of these boreholes varies from 20 to 50 degrees, and the axis of the boreholes is inclined to the longwall axis at 15–30 degrees. Sometimes, more than one borehole is drilled from the same drill site.
