Low permeability is the main constraint on the high-efficiency coalbed methane recovery in
deep coal seams. Hydraulic slotting has been proved to be a favorable method to stimulate …

To construct a molecular model of coal and study the adsorption characteristics from the
perspective of microscopic molecules, the microstructure of coal samples from Pingdingshan …

Breakage plays an important role in mineral processing, and consumes a large amount of
energy. Recently, widespread attentions have been drawn into high voltage pulse breakage …

Pore system in coal is highly heterogeneous, while it is the main occurrence space and
transport channel for coalbed methane (CBM). Electric pulse fracturing (EPF) has been …

The liquid nitrogen freeze–thaw (LN2-FT) method has been widely used to improve the coal
permeability in the coalbed methane (CBM) production. However, the influence of moisture …

With the continuous increase of mining in depth, the gas extraction faces the challenges of
low permeability, great ground stress, high temperature and large gas pressure in coal …

To investigate influence factors of hard rock fragmentation, numerical simulation and
experimental research of hard rock breaking by high voltage pulse discharge are examined …

This study investigates the effects of the carbon disulfide (CS2) extraction on nanopores of
the anthracite samples. Comprehensive pore measurement techniques, including high …

Electric field stimulation is more favour for the enhancement of oil recovery from tight
sandstones compared to conventional resources, since electroosmotic flow of fluids in …

The relationship between breakdown energy and the porosity growth rate were
quantitatively investigated through nuclear magnetic resonance (NMR) and fractal …
