| 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,结果表明:瓦斯异常带是地质异常带。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: | The gas anomaly zone of low gas mine is a place where latent mine hazard may take place.The authors analyzed the geologic characteristics of gas anomaly zone,such as,coal field geological tectonics,seam thickness and its structures,structure of coal solid,hydro-geological conditions,etc.The results indicated that gas anomaly zone was a geological anomaly zone.The authors analyzed the gas anomaly of five blocks behind Panxi Mine.It was found except that CBM was well-reserved in coal seam because of blockage of F7-1 fault at the top,and gas was also recharged by the seam at the depth where abnormal gas emission occurred mostly. |
