摘要
对分源预测法中的煤层原始瓦斯含量进行了深入剖析,并提出了计算干燥无灰基煤样中的瓦斯含量的公式,同时也提出了关于分源预测法中的一些可能认识有偏差的地方,值得相关工作人员借鉴和思考。
The paper deeply analyzed original methane content in different-source prediction and presented calculation formula of methane content in coal sample with dry ash-free basis.Some problems in different-source prediction which was worth of thinking were also pointed out.
