Leichardt Colliery 1978
In December, 1978, a major outburst occurred and killed two men. The ejected coal completely covered the miner and half covered the shuttle car.
The resultant cavity was more than 20 m long. Around 500 tonnes of coal was involved. After this outburst, mechanized mining was stopped and the mine effectively became a research laboratory for a couple of years. The extensive gas investigations have been reported elsewhere
This accident claimed the lives of 2 people.
