An experimental study on behavior of reconstituted low-rank coal under different fluid saturations

Abstract

Carbon dioxide (CO 2 ) storage in deep coal seams significantly alters the petro-physical properties of those coal masses, hence precisely evaluation of such alternations is difficult due to the highly heterogeneous nature of coal. This urges the important of testing reconstituted coal samples (homogeneous) in this regards. The main objective of this study is therefore to investigate the effect of different fluid saturations on the mechanical properties of coal using reconstituted low-rank coal samples. These reconstituted coal samples were made using the powdered Australian brown coal, which were first molded and then subjected to an axial load until the specimens achieve the mechanical pro..
