A coal mine outburst occurred on the 20th of July 2001, in ‘B’ heading of 310 panel. It is the first such incident to have occurred at the mine in its 17 year history. Mining has since the initial days progressed to deeper levels where now the workings are at some 425m below the surface. The issue of greater gas contents with depth is recognised where inseam cross block drainage hole patterns are employed to drain and therefore reduce gas levels in the developing panels and in the longwall. The outburst incident was intimately related with a geological structure, which was covered by inseam drainage boreholes. Subsequent to the outburst further training of the workforce and a full review of the coal mine outburst management plan was undertaken. Enormous experience was gained by all involved in the investigation process.
