金河矿通风系统研究

本科论文AbstractThe Jinhe Coal Mine studied in this paper is located in Xiaozhai Village,Baiguo Town,northwest of Pan County.The mining area is determined according to the mining license.Thecurrent mine is about 1.55km long from east to west,1.64km wide from south to north and1.1444km2 in area.This research is mainly used for the ventilation system research of JinheCoal Mine.The coal seam has simple structure and strong stability.The absolute gas emissionof this mine is 3.80m3/min,which is a high gas mine.Coal dust in this area is explosive.Themine ventilation mode adopts central parallel type,and the ventilation mode is mechanicalexhaust type.This paper analyzes various ventilation parameters of Jinhe Coal Mine from theperspective of theory and practice,and determines the ventilation system of Jinhe Coal Mineby analyzing the scale and mining area parameters of Jinhe Coal Mine.By calculating theventilation requirements of each working face in Jinhe Coal Mine,the air distribution ofeach working face is determined!6).Research and calculation of ventilation resistance in JinheCoal Mine in two stages:easy ventilation and difficult ventilation:Fan type and motor aredetermined by data parameters,such as air volume and air pressure that the fan model mustgenerate:Estimate the mine ventilation cost.Key words:Mining ventilation:coal mine safety;ventilation system
