Key parameters optimization of wind-dust coupling model in ventilation system of fully mechanized excavation face
摘要
Abstract
In order to solve the problem of high dust concentration and long diffusion distance in the heading face under the long-pressure short-pumping ventilation system,based on the actual working conditions of the heading face of the 52509 conveyor head section of Daliuta well,the positions of the dust removal fan and the pressure air duct are set as the key parameters of the research,and the idea of optimizing the dust control effect by controlling the position of the dust removal fan is proposed.On this basis,in order to continue to optimize the dust removal effect,the coupling law between the distance of the pressure air duct mouth and the dust diffusion is studied.The results show that the position of the dust removal fan controls the diffusion of dust by changing the size of the eddy current field,and the dust control effect is the best when the distance from the heading face is 50 m,and the best dust removal effect can be obtained when the pressure air inlet is 10 m away from the heading face.This study can provide a theoretical basis for the selection of key parameters and the improvement of dust control effect of ventilation and dust removal system in mine heading face.关键词
