在井下采掘过程中，常常一瞬间（几分钟甚至几秒钟）从煤体中大量的煤与岩石被抛出，并喷出大量的瓦斯，这种现象叫煤与瓦斯突出，简称突出。原苏联顿巴斯煤田加加林煤矿1969年发生一次煤与瓦斯突出，抛出煤量14200m3，喷出瓦斯量25万m3。发生煤与瓦斯突出事故，不仅采掘工作面 During the underground excavation process, a large amount of coal and rock are often thrown out of the coal mass (often a few minutes or even a few seconds) and large quantities of gas are ejected. This phenomenon is called coal and gas outburst, and is abbreviated as “Outburst”. Coal and gas outburst occurred in the Jagal Mine of the former Soviet Union in the Don Bath Coalfield in 1969, with a coal output of 14,200 m3 and a gas output of 250,000 m3. Occurrence of coal and gas outburst accidents, not only mining face
