Experimental Study on Additive of the Foam Technology for Dust Control in Underground Coal Mines
The advantages of the dust control by foam are demonstrated,such as the high covering power,large contact area,high wetting speed and good isolation performance,which can control the dust efficiently.In consideration of wetting and foaming capabilities of the foam,a new kind of foaming agent with high foam expansion and wetting ability is developed after a large number of filtering and compound experiments by the ROSS-Miles method and water film flotation process method.After the experiments of the foaming ability and the wetting ability to different dust grains with different particle diameters,the results show that the new foaming agent can reduce the surface tension of solid and liquid materials rapidly with good foaming and wetting abilities.After the experiment of experiments,the best additive concentration of the new foaming agent is 0.5%,and a complete new experimental system is set up to produce foam,and the dust-control foam with high performance is produced using new foaming agent.
