Performance analysis of surface goaf gas drainage holes for gas management in an Australian coal mine

, 2019
: This paper focuses on assessing gas drainage performance from vertical surface goaf holes in an operating mine with high specific gas emission rates (~20 m3/t). Field monitoring results of gas flow rate and gas composition collected from individual gas

Optimising adjacent goaf drainage operations by utilising automated control logic at Kestrel South Mine

Seal leakage contributes significantly to methane emissions during longwall mining, occurring when a sealed goaf pressurises with coal seam gas from overlying seams within the sealed goaf subsidence zone, which then leaks into the tailgate roadway.
