摘要

Safety of coal mine and workers is seriously threatened by coal dust, which tends to inhale and explode. Based on several kinds of commonly used surfactants, the physical and chemical properties and the performance of wetting coal of magnetized surfactant solution were experimentally researched. The relationship between surfactant concentration and surface tension was analyzed, the best surfactant for dust suppression effects was defined according to the wettability, the influence of different concentrations of surfactant solution under the condition magnetization on contact angle of coal and PH value of solution were further researched and analyzed. The researches drew the following conclusions: the surface tension of solution decreases as surfactant concentration increases within a certain range; Triton was the best surfactant in the experiment; contact angle of coal decreases greatly after surfactant solution is magnetized, contact angle of coal is the minimum and wetting effect is the best when concentration increases from 0.02% to 0.03%; magnetization surfactant solution has great prospect in mine coal dust suppression.
