上珠岭铁矿禁山深部矿体开采,原设计通风系统为侧翼对角抽出式,矿井主扇选用70B_2-11-18轴流式风机,配套电视为JS127-6型185kW电机。设计依据为年生产能力20万t,最低作业水平-200m。 1980年1月,在通风系统尚未形成的情况下开始生产,年生产能力为5万t,主要作业中段为0m和-33m中段,依靠局扇和自然通风。
On the Pearl Ridge Iron Forbidden Mountain deep ore mining, the original design of the ventilation system for the wing side diagonal extraction, the main fan selection 70B_2-11-18 axial fans, matching TV JS127-6 185kW motor.
