一、研究煤和瓦斯突出机理对煤矿生产建设的重要意义煤和瓦斯突出是在来掘过程中突然地、大量地、强有力地同时向采掘空间喷出煤和瓦斯的一种动力现象.因此,它对人身安全,生产建设的危害性极大.解放二十余年来,全国煤矿共发生突出三千余次.解放初期发生在少数矿井中,由于生产的发展开采深度逐渐增加,新矿井如雨后春笋般的建立,突出矿井数目也就逐渐增多,目前已达近百对矿井,以北票、重庆、湖南红卫、立新、贵州六枝及江西涌山.广东的梅田、红工等矿区较多.突出强度有几吨、几十吨、几百吨到几千吨,目前最大突出强度巳达八千五百余吨.瓦斯涌出量可达几十万和几百万立方米.它对生产建设和人身安全的威胁也日趋严重.
I. Study on the Significance of Coal and Gas Outburst Mechanism in Coal Mine Production and Construction Coal and gas outburst are a kind of dynamic phenomenon of coal gas and coal gas being suddenly and massively and forcefully released into the extractive space during the digging process , Which is extremely harmful to personal safety and production and construction.Over the past 20 years since the liberation, there have been over 3,000 outstanding coal mines in the country. In the early days of the liberation, in a few mines, the depth of production and mining gradually increased. Mushroomed establishment, the number of prominent mines also gradually increased, has now reached nearly a hundred pairs of mines to North votes, Chongqing, Hunan Hongwei, Lixin, Guizhou six and Jiangxi Yongshan. Guangdong’s Umeda, Hong Gong and other mining areas More prominent intensity of a few tons, tens of tons, hundreds of tons to thousands of tons, the maximum intensity has now reached over 8,500 tons. Gas emission up to hundreds of thousands and millions of cubic meters. Its threat to production and construction and personal safety is also becoming increasingly serious.
