Use of Surfactants for Dust Control in Mines. A Laboratory Study

Abstract

The use of water is still the most effective and economical means for dust control in underground coal mines today along with dilution by the ventilation current. Studies have shown that the dust capturing capacity of water is a result of a balance of many intermolecular forces. Surfactants are known to reduce such forces by affecting both the surface tension of the liquid and its interfacial tension against a solid. Surfactants can be added to the water sprays to facilitate the dust capturing capacity. A laboratory scale model has been developed in which surfactants were added to the spraying water and preliminary data indicates positive results.
