Abstract

Abstract: According XV1301 mechanized mining face parallel double U-ventilated actual site conditions in SiHe. The hydrodynamic model are established to simulate the comparative analysis of the main intake airway if XV13013 case of constant air volume ratio XV13011 different auxiliary inlet Lane XV13015 another intake air flow and air flow lane on the flow field and goaf gas migration characteristics. Studies have shown that parallel double U-ventilation, if XV13011 auxiliary inlet air volume and XV13015 another lane into the wind air volume ratio of 3:1, Alley, can significantly reduce the upward corner gob centralized air leakage, which can effectively alleviate the upper corner and the main return airway gas accumulation phenomenon. This study is the ratio of gas and air flow control optimization theory.

Key words: parallel double U-shape ventilation system, goaf, air volume ratio, CFD simulation
