Based on the model test, the regularity of Dongshan coal underground gasification was obtained.

通过地下气化模型试验，获得了东山煤地下气化过程的一般规律。

The coal underground gasification technique belongs to a kind of adopting the coal method specially, it belong to nations found.

煤炭地下气化技术属于一种特殊的采煤方法，它属国际首创。

youdao

Thereby it has provided an essential scientific foundation for us to formulate technology schemes of the underground gasification.

从而为制定地下气化技术工艺方案，提供了必要的科学依据。

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.
