Excerpt

An outburst of coal and gas is defined as the rapid release of a large quantity of gas in conjunction with the ejection of coal, and possibly associated rock, into the working face or mine workings. The sudden and violent nature of an outburst is hazardous through the mechanical effects of particle ejection and by asphyxiation, poisoning, and possible explosion from the gas emitted. With an increase in mining depth and production, the intensity and frequency of outburst tend to increase. …
