The Resources Regulator has released a new safety video highlighting the dangers of frictional ignition and the process operators should follow to minimise occurrences.
Frictional ignition occurs when methane gas is ignited by intense heat and a spark generated when a cutting machine strikes hard rock.
Most incidents of frictional ignition in coal mines occur when cutting along the longwall face.
The video explains how the combination of heat, fuel and oxygen can lead to a frictional ignition event and how these factors are best controlled.
In particular, the video discusses how the key contributing elements of frictional ignition events – picks, sprays and ventilation – should be inspected and maintained to minimise risk and future occurrence.
