| 摘 要： | 低瓦斯矿井的瓦斯异常带是发生煤矿事故的隐患。通过井田地质构造、煤层厚度及其结构、煤体结构、水文地质条件等瓦斯异常带地质特征分析表明,瓦斯异常带与地质异常带关系密切。对潘西矿后五块段瓦斯异常带进行了分析,发现F7-1下盘断块的煤层,除煤层瓦斯保存条件较好外,其上部受阻于F7-1断层,下部又有深部本煤层瓦斯补给,异常涌出的次数也最多。 |

| Abstract: | Gas abnormal zone in a law gaseous mine is a potential hidden peril of gas accident.Study of geological features,seam thickness and structure,coal block texture,hydrogeological conditions in gas abnormal zone and so on indicates that gas abnormal zone is closely related to geological abnormal zone.This paper deals with gas abnormal zone in the last five blocks in the Panxi Mine.Study results indicate that gas burst occurs mostly in coal seam in the lower wall of fault F7-1. |
