With the rapid urbanization and shortage of energy, the construction of underground projects
such as urban rail transit, hydropower stations, and coal mines is a general trend. Dust …

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 …

The regulation of surfactant on the wettability of bituminous coal surface is influenced by its
hydrophilic structure. Based on the water absorption simulation and contact angle …

Water injection in coal seams is an effective technique for preventing and controlling dust
disasters in coal mines. However, there is a lack of quantitative evaluation of water transport …

Coal seams are naturally occurring geological media offering tremendous potential for gas
storage. The wetting characteristics of coals at typical geological formations underpin a …

To investigate the effect of different ionic liquid composite solutions on the wettability and
chemical structure of coal dust, 14 ionic liquid compound solutions with various composite …

The injection of surfactant solutions into coal seams is one of the most critical technical
means of preventing coal mine disasters. It can effectively prevent coal and gas outburst …

Water-based SiO 2 nanofluid, a wetting agent, has been proved to be feasible in improving
the control effect of coal seam water injection against coal and gas outburst. However, the …

The water wettability of coal dust was very important for dust control when using water-
based dust suppressant materials. The coal dust wettability strengthened by surface active …

Acidification technology is an important measure for enhancing the extraction of coalbed
methane from seams with low permeability and abundant minerals, and the acidification …
