自六十年代以来,各产煤大国都十分重视煤与瓦斯突出的地质研究,发表了大量论文,提出了数十种假说。在众多的假说中,综合作用假说越来越被大多数研究者所接受。从分析突出本质及其分类理论的现状出发,笔者认为,煤与瓦斯突出是由裂隙-孔隙结构、有应力和饱含瓦斯的煤层,与采掘工艺因素相互作用的结果。在采掘过程中, Since the 1960s, all coal producing countries have attached great importance to the geology research of coal and gas outburst, published a large number of papers and put forward dozens of hypotheses. Among the many hypotheses, the synthetic hypothesis is increasingly accepted by most researchers. Based on the analysis of the prominent nature and the classification theory, the author thinks that the coal and gas outburst are the result of the interaction between the coal seam with fissure-pore structure, stress and gas-saturated, and mining process factors. In the mining process,
