摘要:

通过对南温河钨矿一采选厂1232m中段南翼通风能力不足、有效风量率低、采空区漏风、局扇布局混乱等问题展开分析,提出了受控循环通风新技术应用的构想,在优化计算了循环系统循环率、循环风量、净化效率等参数的基础上,得出采用受控循环通风系统,可使系统区域有效进风从49.45m3/s增加为84.66m3/s。对比采用传统通风系统,将用风地点的风量由49.45m3/s增加到84.66m3/s所耗功率是原系统的5.021倍,而采用受控循环通风系统时,所耗功率只是原来的1.845倍,相对于一个生产能力为每年450kt的区域而言,应用受控循环通风技术对矿山降低通风能耗具有重要的应用意义,可有望取得较好的经济效益。

Abstract:

By using the controlled circulating ventilation to optimize and transform, the problems of weak ventilation, low efficiency of effective air volume, disordered layout of local fan in 1232m midpiece in south side in Mining plant of Nanwenhe river tungsten mining was analyzed. Based on reasonablely selecting parameters of recirculation rate, recirculation air volume and purifying efficiency, it was found that, in the situation, the controlled circulating ventilation could make the air volume increase to 84.66m3/s from 49.45m3/s at the working face that effective dowmcast air keep stable. In traditional ventilation system, the powder consumed increased 5.021 times when air quantity at site increased  to 84.665m3/s from 49.45m3/s, comparatively, when controlled circulating ventilation was used, powder consumed was increased just 1.845 times. In terms of a mining area of capacity of 450 000 tons per year, it was of significance to apply controlled recirculation ventilation technology, which could be expected to obtain good economic benefit.

Key words: underground mining, ventilation problems, controlled recirculation ventilation technology, energy saving
