Synthesis and characterization of water injection fracturing fluid for wetting and softening coal seam

Gang Zhou et al.

Summary: This study aimed to achieve dust control at coal mining faces through the use of a new carboxylic anionic surfactant, providing a safe working environment for underground operators. Testing showed the product had low surface tension, high shear viscosity, and low filtration, with superior wetting and softening effects on coal compared to traditional fracturing fluids. Through molecular dynamics simulations, it was determined that the product could effectively connect with coal molecules and greatly improve coal wetting.

Experimental investigation on combined modification for micro physicochemical characteristics of coal by compound reagents and liquid nitrogen freeze-thaw cycle

Weibo Han et al.

Summary: An experimental study on combined physicochemical modification of coal was conducted to meet the urgent demands for efficient resources and sustainable development. The optimal physicochemical modification scheme included the use of mine water, SLS, nitric acid, and [Bmim]Cl for freeze-thaw cycles, resulting in significant improvements in coal wettability, porosity, and permeability. The synergy of combined modification and multi-field coupling led to a substantial increase in porosity and permeability, while reducing surface tension and enhancing coal mining safety and production efficiency.
