Working face is the central area in mine. and the ventilation system of working face is an important link for ensuring the operation safety in working face and producing a good working environment. Based on the theory of the flow of airflow and gas delivery in working face, and by means of field test, model simulation test and computer simutlation study, etc., law of the flow of airflow and gas delivery in working face of the strike retreating U-ventolation system. U+L—ventilation system (taking tailgate ventilating). retreating Y-ventilation system generally used in China and having developing future is emphatically studied.
