Sudden release of coal and gas
A sudden coal and gas outburst is a spontaneous instantaneous destruction of part of the coal seam near the face of a mining excavation, accompanied by the ejection of coal and intensified gas emission. It occurs due to an abrupt change in the stress state of a coal seam saturated with methane, carbon dioxide or their mixture as a result of its sudden exposure and uncovering by the mining excavation, rapid penetration into the coal seam (during blasting, collapse of coal on steep seams) or during advancement of the face in an unevenly strong and stable seam (near geological disturbances)
