摘要
天然焦具有良好的物性条件,含有大量的瓦斯气体,是一个理想的储气层。但在煤矿生产中却经常是遇到天然焦因瓦斯增大而中止生产的现象时有发生。本文根据天然焦的物性条件,结合阜新矿区井下实践,论述了煤层气在天然焦内的储存特征,并指出了在煤层气开发利用方面应予以重视的问题。
Natural coke has good conditions of physical character,and contain abundant coalbed gas,is an ideal reservoir of gas.But during coal mining,often stop production because of gas content in natural coke increase.According to physical conditions of natural coke and combine with mining practice of Fuxin coal mine,the paper has reviewed preservative features of coalbed gas in natural coke,and indicated some problems ought to pay attention on exploitation and application of coalbed gas.
