煤与瓦斯突出是煤矿生产中严重的自然灾害,是煤矿安全生产的一个重大难题。全国统配煤矿有16%的矿井是瓦斯突出矿井,有的矿区突出矿井比例超过50%。由于瓦斯突出是一个复杂的动力过程,它的发生受一系列自然和工艺因素所控制。由于突出的灾害性,它的发生和发展过程不能直接观测,也难以在实验室模拟。因而煤与瓦斯突出预测和防治仍是一个难度很大并且存在不同观点的研究课题。
Coal and gas outburst are serious natural disasters in coal mine production and are a major problem in coal mine safety production. 16% of the coal mines nationwide are gas outburst mines, some of which are over 50% out of proportion. Because gas outburst is a complicated dynamic process, its occurrence is controlled by a series of natural and technological factors. Due to the outstanding disastrousness, its occurrence and development process can not be directly observed, and it is difficult to simulate in the laboratory. Therefore, coal and gas outburst prediction and prevention is still a very difficult and there are different points of view of the research topic.
