Poor coal wettability limits the effectiveness of water injection in coal seams. Nanofluids and
surfactants can improve the coal wettability. In this paper, the impact of four types of …

It has been proven that SiO2–H2O nanofluids have great application potential for water
injection in coal seams. To explore the influences of the particle size on the stability and …

The accurate identification of gas migration channels and enrichment regions is essential for
the utilization of gas resources and safe coal mine production, which are closely related to …

In the mining process of close distance outburst coal seams, a large amount of gas is
desorbed and discharged into the atmosphere causing the waste of coal bed gas resource …

Coal reservoir usually requires stimulation to enhance coalbed methane (CBM) production.
As a novel stimulation method, microwave heating contributes to methane desorption and …

In coal mining, the gas pre-drainage boreholes in front of working faces are often repeated
loading and unloading. Studying the failure characteristics of boreholes under cyclic loading …

Matrix acidification is a potential method for increasing the permeability of coalbed methane
reservoirs. However, current research on the acid corrosion process is still unclear, and acid …

Gas drainage is an effective technology for gas control in coal mines. A high borehole-
sealing quality is the fundamental precondition for efficient gas drainage. The expansibilities …

Microwave-LN 2 cyclic processing (MLCP) is a clean and high-efficiency anhydrous
fracturing technology. The change in the porous structure of coal after freeze-thaw cycles …

CO 2 foam fracturing technology shows promise concerning enhancing coalbed methane
(CBM) recovery and realizing CO 2 geo-sequestration in deep un-mineable coal seams …
