Tectonic coal, formed after the intact coal being subjected to long-term intense squeezing,
shearing and deformation, is characterised by brittle or ductile damaged coal body, with the …

As key flow properties for coalbed methane production, greenhouse gas reduction through
CO 2 storage in coal and gas drainage to improve mining safety, knowledge of gas diffusion …

Eleven coal samples of different metamorphism are studied with regard to their pore
structures. Both low-pressure nitrogen gas adsorption (LP-N 2 GA) and scanning electron …

In this paper, the pore structures of three different rank coals sampled from China
(anthracite, bituminous coal and lignite) were characterized by CO 2 and N 2 adsorption …

Studies on the mechanisms of shale gas adsorption are of great significance for shale gas
accumulation and reserves evaluation. In order to investigate the mechanisms of shale gas …

To characterize the pore features of outburst coal samples and investigate whether outburst
coal has some unique features or not, one of the authors, working as the member of the …

Small-angle and ultra-small-angle neutron scattering (SANS and USANS), low-pressure
adsorption (N2 and CO2), and high-pressure mercury intrusion measurements were …

The concept of increased methane recovery with simultaneous CO 2 sequestration in
unconventional reservoirs like gas shales has been studied extensively. A clear …

A series of methane (CH4) adsorption experiments on bulk organic rich shales and their
isolated kerogens were conducted at 35° C, 50° C and 65° C and CH4 pressure of up to …

It is important to understand the disaster-causing mechanism of dried water-immersed coal
by investigating the influence of water immersion on the coal pore structure. In this study, low …
