Abstract:
Actual operational data from a longwall mining system were investigated regarding the intersection of fault-type geological discontinuities in the coal seam and the performance of preliminary in-seam degasification boreholes within these zones. Based on an analysis of this data, the study established the patterns of change in methane emission rates into the working area, downtime required for face ventilation, and gas yield parameters from the seam into degasification boreholes, depending on the boreholes' positioning relative to the zones of geological discontinuities.
Keywords:
fault-type geological discontinuities, hazard zone, methane emission, methane flow rate, preliminary in-seam degasification
