本科论文AbstractThis paper mainly studies the ventilation system of baoping coal mine,which islocated in the southwest of toutunhe,zhunnan coalfield,changji cityAccording to theoperation scope of the mining area according to the relevant documents,the current mine fieldis about 1.30km long in the east-west direction,0.811km wide in the south and about1.0543km2 in the north.In the mining area,there are 4-5,7,9-10,14-15 coal seams and other4 layers of minable coal seams.The 4-5 and 7 coal seams are semi-bright briquette,the 9-10coal seams are semi-dark,and the 14-15 coal seams are dim.The coal dust in this mine isexplosive,and the amount of coal dust explosive rock powder is between 8085%.Therefore,the coal mine construction unit in the production should strengthenventilation and dust removal work,so as to avoid production accidents.This paper studied the ventilation system of baoping mine,air volume calculation and airvolume distribution analysis,ventilation resistance calculation,main ventilator selection andestimated mine cost of baoping mine.Key words:ventilation system:Air volume calculation:Ventilation resistance
