摘要

According to the status of 7312-2 light-face in Longdong Coal Mine, the technology of three-phase foam and its application were studied. The three-phase foam and its extinction theory are particularly introduced in this paper. The primary form of coal ash and yellow mud samples were received by analysis with instrument Laser Partical Sizer, and the coal ash was determined as the experimental material. With experiments of the proportion of ash and water and performance of foaming agent, the optimum proportion is 1:4, and the performance of foaming agent is best when the critical micelle concentration is 0.7%. Continuously, through matching experiments with foaming agents, No.3 and No.6 foaming agents were selected finally, and matching proportion was 1:1. Based on the practice of 7312-2 light-face, the process flow of three-phase foam and its primary technical parameters were designed. The monitoring results of the concentration of CO and temperature show that the effect of the three-phase foam for extinction is outstanding.
