大同煤田北部瓦斯赋存规律

Gas Preservative Law in Northern Datong Coal-field

通过瓦斯地质图的编制,总结了大同侏罗纪煤田北部的瓦斯赋存规律,分析出高瓦斯区呈异常的带状分布规律,一个是沿十里河的东西向条带,另一个是从忻州窑—云岗—上深涧的北西向条带。在此基础上探讨了石炭纪煤层气体向侏罗煤系运移的可能性,并用聚类分析方法进行了判断、验证,指出了气体运移的通道。

Through draw up gas geological map,Summarized gas preservative law in north part of Datong Jurassic Coal-field,Which that gas showing zonal distribution,and one is east-wext zone along shili river,the another one is north-west zone along Xinzhouyao-yungang-Shangshenjian.And also probed into transportable possibility of coal bed gas from carboniferous coal measures to Jurassic coal measures,and predicted transportable passage of gas.
