Developing chemical stimulation techniques and understanding its mechanism are …

Efficient, safe, and environmentally friendly methods for the low-carbon utilization of coal are
required to exploit this resource as a source of cleaner energy. Tar-rich coal can produce a …

Technical advances in horizontal drilling and hydraulic fracturing have significantly
improved commercial shale gas development. However, current shale gas development has …

Acid fracturing is a potential method to resolve the mineralization restriction around wellbore
and enhance the permeability in coalbed methane extraction. The previous study mainly …

Microwave-assisted pyrolysis (MWAP) provides distinctive heating for the conversion of coal
into liquid fuels. This work investigated the effects of MWAP on the microstructure of …

In order to enhance the wetting performance of surfactants to coal dust and reduce the harm
caused by coal dust, different concentration of NaCl solution was added to the anionic …

Coal pillar fragmentation caused by mining stress will cause multiple goafs in series on the
isolated island's small coal pillar working face. Due to the unclear rule of air leakage in the …

Coalbed stimulation is a process of increasing coalbed methane (CBM) production by
opening, enlarging, and extending the length, width, and connectivity of pores and …

In-situ coal seam is generally under the stress constraint condition. However, the powder
coal is often adopted to study gas diffusion dynamics in the laboratory, in this case, the …

The macromolecular structure of coal governs the generation and expansion of
