DOI: 10.1016/j.coal.2018.01.007

Abstract: We present an experimental method to study time-dependent, CO2-induced, local topography changes in mm-sized composite samples, plus results showing heterogeneous swelling of coal and shale on the nano- to micrometer scale. These results were obtained… read more here.

DOI: 10.1016/j.ijmst.2019.02.006

Abstract: Abstract Coal and coal-shale undergo low-temperature oxidation when exposed to air, potentially leading to spontaneous combustion. Coal-shale found in association with coal seams vary considerably in their intrinsic properties and spontaneous combustion liability index. Fourteen… read more here.

DOI: 10.1021/acsomega.3c10376

Abstract: Coal shale gas is an important type of shale gas. The microscopic pore size distribution and pore structure characteristics of coal shale determine the macroscopic storage and transportation of coal shale gas. In order to… read more here.
