Numerical Simulation of Gas Migration in "U Shape Ventilation + High Pumping Lane" Based on FLUENT

YANG Yang;ZHAO Yao-jiang;College of Mining Engineering,Taiyuan University of Technology;  
The mass conservation equation,momentum conservation equation,continuity equation and theoretical basis for the establishment of the mathematical model,numerical simulation software FLUENT analysis of the U shape and U shape ventilation system ventilation system + high pumping lane two forms of S2107 working face mining fracture field gas concentration distribution,comparison and analysis of the gas concentration of gas the concentration distribution of two kinds of form and the upper corner,and through on-site verification of high drainage roadway drainage,drainage to provide scientific theoretical basis for the treatment of upper corner gas and goaf gas.
