coal seam gas

基本解释

This paper deals with problems about thermo-dynamic theory of coal-seam gases.
本文讨论了有关煤层气体的若干热力学理论问题。
The author considers that outburst of coal-seam gases is not only a dynamic phenomenon, but also a very complicated thermodynamical conversion process of energy.
作者认为，煤层气体的突出不仅是一种动力现象，它还是一种复杂的热力学过程。
The author also applies the entropy discrimination of thermo-dynamics to outburst of coal-seam gases and presents "Outburst index of coal-seam gases" for predicting proneness of outburst.
作者还应用热力学中的“熵值判别法”提出了“煤层气体突出熵指数”，作为判断煤层气体的突出倾向性。

It facilitates a cheaper way of capturing greenhouse gases, which can either be pumped back into the coal seam, or be re-used to inject oilfields to increase recovery rates (OK, even I see the irony here).
