安全工程-宝平矿通风系统研究论文

本科论文摘 要本论文主要研究宝平煤矿的通风系统，该矿井的地理位置位于昌吉市准南煤田头屯河西南部。该区地貌总体特征，受控于新地质构造运动和头屯河迳流切割，以河床阶地、台地地貌为主。依据有关证件拟定的矿区作业范围，现井田东西方向约有1.30km 长，南北约有 0.811km 宽，面积约 1.0543km2。矿区有 4-5、7、9-10、14-15 煤层等 4 层可采煤层，4-5、7 煤层为半亮型煤，9-10 煤层为半暗型，14-15 煤层为暗淡型。由于该矿煤尘具有爆炸性，其抑制煤尘爆炸岩粉量在 80～85%之间。因此，煤矿建设单位在生产中应加强通风及除尘工作，以免酿成生产事故。该本论文对宝平矿通风系统的研究的内容包括矿井通风方式、通风方法、风量计算及风量分配分析，通风阻力计算，对宝平矿主要通风机选型以及概算矿井费。关键字：通风系统；风量计算；通风阻力本科论文Abstract This paper mainly studies the ventilation system of baoping coal mine,which is located in the southwest of toutunhe,zhunnan coalfield,changji city[1].According to the operation scope of the mining area according to the relevant documents,the current mine field is about 1.30km long in the east-west direction,0.811km wide in the south and about 1.0543km2 in the north.In the mining area,there are 4-5,7,9-10,14-15 coal seams and other 4 layers of minable coal seams.The 4-5 and 7 coal seams are semi-bright briquette,the 9-10 coal seams are semi-dark,and the 14-15 coal seams are dim.The coal dust in this mine is explosive,and the amount of coal dust explosive rock powder is between 80 ~ 85%.Therefore,the coal mine construction unit in the production should strengthen ventilation and dust removal work,so as to avoid production accidents.This paper studied the ventilation system of baoping mine,air volume calculation and air volume distribution analysis,ventilation resistance calculation,main ventilator selection and estimated mine cost of baoping mine.Key words：ventilation system：Air volume calculation；Venti...
