Report on hydrogen sulphide experience at Southern Colliery

Hydrogen sulphide (~S) as a seam gas has occurred in several locations in the Gennan Creek seam at Southern Colliery . This paper overviews the techniques developed to quantify the ~S content of the seam, overviews research into controlling and reducing ~S emissions from the seam, and details the procedures used to mine through the ~S zone in 702 longwall panel. Learning points from research and mining experience are reviewed for application in the next longwall block.
