Hydraulic Fracturing

As part of the extraction process, the water and gas trapped in coal seam deposits needs to be released to allow it to be pumped to the surface.
In some cases, a process called hydraulic fracturing – also referred to as ‘fraccing’ or ‘fracking’ is used to stimulate the coal seam. Where fracturing is used, fluid is pumped under pressure into the coal seam to open up fractures, and release the gas that is trapped in the coal seams.
