讨论了关于矿山设计各阶段予测沼气涌出量的重要性。详述了予测沼气危险性的必要的有关矿山设计的特別问题。揭示了采煤工作面及掘进工作面中沼气涌出量的最高值和平均值之间的关系。
Discussed the importance of predicting the amount of methane emission at each stage of mine design. The special issues relating to mine design that are necessary to predict the risk of biogas are described in detail. The relationship between the highest value and the average value of methane emission in coal mining face and heading face is revealed.
