Coal, containing all the elements that are present in nature and more than 200 minerals, has
a complex chemical structure, making it one of the most complex geological materials …

Research on pyrolysis mechanisms has attracted significant attention as they can efficiently
assist in coal resource utilization. Although experimental techniques have significant …

Oxidative extraction has become an economically viable option for recycling lithium (Li) from
spent lithium iron phosphate (LiFePO 4) batteries. In this study, the releases behaviour of Li …

A suitable model can reflect the properties of coal well. In this study, the properties of
HongLiuLin (HLL) coal were studied through industrial analysis, XPS, 13 C NMR and FTIR …

Chemical stimulation is a potential technology for coal permeability enhancement.
Developing chemical stimulation techniques and understanding its mechanism are …

Owing to the sub-economic permeability, coalbed methane (CBM) reservoir usually requires
stimulation. Novel CBM stimulation approaches have been proposed such as CO 2 …

The macromolecular structure of coal governs the generation and expansion of
micro/mesopores, contributing significantly to the storage and transport of coalbed methane …

The reactions between oxygen molecules and functional groups are the internal cause
leading to heat release and the corresponding coal spontaneous combustion. However, the …

Carbon dioxide phase change fracturing is an effective permeability enhancement
technology, and its influence mechanism on the coal microstructure remains to be further …

In the mining of multiple coal seams, geological fracture may cause water from aquifers to
accumulate in the overlying gob. Residual coal in the overlying gob after water immersion …
