Mathematical simulation study on characteristics of three-phase foam seepage in goaf
Abstract：To study the characteristics of three-phase foam seepage in goaf,with computational fluid dynamics theory,constructed the mathematical model of three-phase foam seepage in goaf.The process of three-phase foam seepage in fully mechanized caving face goaf was simulated,gained the theoretical values of three-phase foam＇s flow scope and analyzed its influencing factors.Research shows that stack height of three-phase foam seepage in goaf is 3.62 m,and the highest point located in upside of pipe outlet.The covering width in strike direction is 36.9 m;stack height and covering width of three-phase foam are seriously influenced by dip of working face and flow volume of three-phase foam.
