摘 要 矿井通风设计在整个矿井的设计内容中占有重要的地位，是保证井下安全生产和矿工生命安全的重要环节。矿井通风的主要任务是向井下持续输送新鲜空气，稀释并排除多种对人体有害的气体，为井下提供安全舒适的工作环境。 此次设计根据煤矿煤田地质条件，当地气候条件，可采煤层构造等情况，设计最有利的通风系统，以最实用，可靠的方式向井下各工作地点提供新鲜稳定的风流，从而保证井下工作人员的身体健康和工作安全。本设计根据的是大同鹊山精煤有限责任公司，可开采侏罗系大同组3、4、7、8、11、12、14号煤层，井田面积10.9214km2，生产规模为110万吨/年。矿井采用3个井筒开拓，主斜井、副斜井和风井。矿井采用中央分列式通风方式，抽出式通风，矿井在容易时期和困难时期负压分别为931.01Pa和1331.50Pa。在风井口配备两台2K60型矿用防爆轴流式通风机两台，一台运转，一台备用，总回风量为68m3/s，选择Y-315L1-2电机，功率为160kw。 关键词：矿井开拓；矿井通风设计；通风机 ABSTRACT Mine ventilation design in the design of the whole mine content occupies an important position, is to ensure mine safety production and an important part of the miners life safety. To underground mine ventilation is the main task of the continuous conveying fresh air, dilution and ruled out a variety of harmful gas, for underground to provide a safe and comfortable working environment. This design according to the coal mine coal field geological conditions, the local climate conditions, minable seam structure, etc., design the best ventilation system, in the most practical and reliable method to mine the work site to provide fresh and stable wind flow, so as to ensure the health of underground workers and job security. The design on the basis of datong queshan plant co., LTD., is recoverable Jurassic datong group 3, 4, 7, 8, 11, 12, 14 # coal seam, mining field area of 10.9214 km2 and the production scale of 1.1 million tons/year. Mine adopts three shaft, the main slope, slope and wind well. Mine adopts central such ventilation method, drawer-type ventilation, mine in easy and difficult time during the period of negative pressure of Pa Pa 931.01 and 931.01 respectively. In wind well equipped with two type 2 k60 mine explosion-proof axial flow fan two, a functioning, a backup, total air volume of 68 m3 / s back, choose l1 Y - 315-2 motors, power of 160 kw.
