Accurate prediction of methane resource reserves is a key step in developing and utilizing abandoned mines. However, due to mining activities' interference, the load environment remaining coal has changed, which affects adsorption migration gas leads wrong evaluation reserves. To study influence on mines, we analyzed space–time evolution residual We divided into column-type loose-type. Methane experiments were carried out by changing axial samples experimental device. The results show that:...
The influence mechanism of the adsorption fatty alcohol poly(oxyethylene) ether (AEO9) on wettability anthracite coal was studied by means experiments and simulations. First, contact angle surface tension were measured. When AEO9 concentration 0.5 wt %, smallest, which 10.28° 25.39 mN m-1, respectively. X-ray photoelectron spectroscopy (XPS) indicated that content C-O functional groups increased 20.76% after AEO9. molecular orbital energy electrostatic potential calculated density theory...
