The objective of this study is to quantitatively describe the CH 4 adsorption capacity of coal
through microscopic pore properties. In this work, the micropore volume distributions (MPVDs…

2019 (COVID-19) is either indirect (from studies of influenza, severe acute respiratory
syndrome and Middle East respiratory syndrome) or from several observational studies and …

Low-pressure CO 2 adsorption is an important tool for quantitatively characterizing the
micropore characteristics of porous materials. While only adsorption data obtained at adsorption …

This study examined the influences of crushing on the microporous and ultramicroporous
structures of coal by low-pressure CO 2 adsorption (LPGA-CO 2 ). Many replicate experiments …

The crushing energy of coal plays an important role in mining, gas extraction, occurrence of
outburst accidents, and coal pulverisation engineering. To calculate the crushing energy of …

The low efficiency of coalbed methane (CBM) extraction not only causes a great waste of
energy resources and environmental pollution but also poses potential safety risks during coal …

The uniaxial creep test offers a robust approach for investigating the creep behavior of coal
particles, while an empirical creep model based on the extended Langmuir equation …

Tectonic coal is a necessary condition for coal and gas outburst, and its pore structure is
dramatically altered. The pore structure of tectonic coal has unique characteristics in terms of …

Production of a large amount of gas during outbursts will cause greenhouse effects, which
will impact the atmospheric environment. In this study, some inherent properties of pulverized …

Seepage pores are the main space for methane transport in the coal seam. To further
investigate variation laws of seepage pores with stress, this study established a new method …
