ABSTRACT
An outburst of coal and gas is 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 the outburst is hazardous through the mechanical effects of particle ejection and by asphyxiation, poisoning and possible explosion from the gas produced. With an increase in depth of mining and production, outburst intensity and frequency tend to increase, although this trend is somewhat masked with advances in understanding the phenomena and application of new prediction technologies and control measures.
