变电硐室作接力风室在铝土矿山基建通风中的应用
|
摘要
针对奥家湾I号矿基建工作面多、巷道长、通风条件差的问题,提出利用变电硐室作接力风室,形成安全经济的二级供风系统,大大改善了通风条件。改造后各巷道最高CO浓度为23ppm、最高SO2浓度为5ppm、最高呼吸性粉尘浓度为5mg/m3、最低风速为0.16 m/s,各项指标均达到井巷施工作业环境标准,不仅保证了工人的安全健康,并且大大提高了基建速度,促进平巷月炮掘记录达到168 m,较合同工期提前半个月贯通,取得了较好的经济效益。
Aimed at the infrastructure problems of multiple working faces,long tunnel and poor ventilation,the application of substation chamber as a plenum was proposed in the No.1area of Aojiawan mine.Thus,a secondary ventilation system with safe and economical effect was established,and the ventilation conditions were greatly improved.After application,the highest CO concentration,the maximum SO2 concentration,the highest respirable dust concentration and the lowest wind speed were respectively 23 ppm,5ppm,5mg/m3 and 0.16 m/s,which all reached the working environment standards of roadway construction.It not only ensured the safety and health of workers,but also greatly improved the speed of infrastructure.The month excavating record achieved 168 m,which was two weeks earlier than the contract duration,with good economic results.
