underground gasification

基本解释

The developmental and variable rules of heat value for coal gas of underground gasification without shaft style in steep coal seam is described.
指出了急倾斜煤层无井式地下气化煤气热值的发展变化规律。
A program for combination development of coalbed methane and underground gasification has been suggested. The program is considered to be feasible technically and economically by analysis.
本文提出了综合开发煤成气和煤地下气化的方案。通过分析，认为该方在技术和经济上是可行的。
The gasification face development rate of the test coal changes gently in underground gasification process, which indicates that the underground gasification of lean coal has high stability.
气化工作面扩展速率在供风点附近出现最大值，变化平稳，瘦煤地下气化具有较高的稳定性。

With shale gas still very cheap in North America, Underground Coal Gasification may not make major progress on this continent anytime soon.
FORBES: Underground Coal Gasification: A Trend Worth Watching
At that time underground coal gasification (UCG, also known as in-situ coal gasification or ISCG) was increasingly seen as a relatively low-impact way of tapping the huge US coal resource, while potentially managing emissions.
