Abstract

Direct methods of measuring the gas content of coal beds, including calculation of the lost gas, are reviewed. In determining the gas content of the coal in productive beds within the Kuznetsk Basin, the distinctive properties of the coal must be taken into account: specifically, its high natural gas content; and hazardous dynamic gas releases in mine workings. That is especially common for valuable coking coal.

确定煤层的瓦斯含量

摘要

回顾了测量煤层含气量的直接方法，包括计算损失的瓦斯。在确定库兹涅茨克盆地内生产层煤的含气量时，必须考虑煤的独特特性：特别是其高天然气含量；以及矿山作业中危险的动态气体释放。这对于有价值的炼焦煤来说尤其常见。
