| 摘 要： | 矿井瓦斯危险程度与煤层中瓦斯赋存状况及其泄出方式有关,并取决于多种地质条件和采掘工艺。其中,煤特征条件特别重要。本文分析了湖南省的5种矿井瓦斯危险类型以及相应的煤特征条件,提出了“煤特征指数(I_c)”这一概念。I_c是一项评价矿井瓦斯危险程度的综合指标。研究表明,矿井瓦斯危险愈严重,则其I_c值愈高。应用该项成果预测了16对矿井的瓦斯危险类型,取得了满意的效果。

| Abstract: | There are five Danger types of mine gas in Hunan province, which could be determinated by means of "Characteristic Index of coal (Symbol:I_(c)) ". "I_(c)" is a composite Index. It can reflect the difference of the characteristic of coal of these types.The result of testing and verifying in 16 mines is satisfied on the whole. |
