摘要:The use of surfactants has a significant impact on the safety of
mining operations in order to prevent dynamic processes, prevent dust. The
interfacial angle is the main indicator characterizing the interfacial
interactions for heterogeneous multicomponent solid bodies, coal and
solutions. The problem of development of modern methods for
determining the interfacial angle at the coal-water-gas boundary is
considered. The results of the research study of the change in the coalliquid-gas
interfacial angle are presented. The influence of various coal
properties and characteristics on the interfacial angle value is shown. The
influence of the interfacial angle on wetting and filtration processes, the
features of the experimental methods for the interfacial angle determination
are shown. A model of the coal surface consisting of four main
components is proposed. The main attention is paid to the moisture content
of coal and capillaries as the main factors determining the properties of
coal. An analytical method for determining the interfacial angle of coalwater-gas
is proposed.
