Gas Control | Introduction | underground COAL

There are 4 ways of capturing/ containing gas to keep it out of airways: Drilling boreholes into the coal seam (possibly also in adjacent seams) prior to mining and connecting these to a pipe range to remove any gas to a place where it can be dealt with, most commonly the surface. Usually a vacuum is applied to the pipe range to enhance gas ...
