位于山西东南部的阳城县共有各类煤矿87座,其中,高瓦斯矿井就有42座。由于煤层赋存条件复杂,一些矿井瓦斯相对涌出量达170立方米/吨,绝对涌出量达43立方米/分以上,是山西省的瓦斯重灾区之一。从1986年到2000年的15年时间里,全县共发生瓦斯事故26起,死亡107人,经济损失上亿元,给人民生命财产造成了重大损失。 There are 87 coal mines in Yangcheng County, southeast of Shanxi Province, of which 42 are high-gas mines. Due to the complicated occurrence conditions of coal seams, some mines have a relative emission of 170 m 3 / t and an absolute emission of more than 43 m 3 / m, making them one of the hardest hit areas in Shanxi Province. In the 15 years from 1986 to 2000, a total of 26 gas accidents occurred in the county, killing 107 people and losing hundreds of millions of yuan of economic losses, causing heavy losses to people’s lives and property.
