Mining a coal seam below a heating goaf with a force auxiliary ventilation system at Longhua underground coal mine, China
Extraction of a coal seam which lies not far below a heating goaf can be a major safety challenge. A force auxiliary ventilation system was adopted as a control method in successful extraction and recovery of the panel 30110 of the #3−1 coal seam, which is about 30–40 m below the heating goaf of the...
