千米深井热害的防治

Prevention and Treatment of Heat Damages at Thousand-Deep Shaft

分析了星村煤矿矿井高温高湿产生的原因及其危害性,制定了切合实际的降温除湿技术,采取预冷进入矿井空气,安装局部降温机组,在掘进工作面放置冰块,利用冰块融化降温和个体防护等措施,为矿井安全生产创造了较好的作业环境。

This paper, through analysis on causes to high temperatures and high moisture at Xing Cun Coal shaft and its damages, developed an effective cooling and dehumidification technology to create a better operating environment for the mine safety production, including ice melting temperature deduction and personnel protection measures such as to pre-cool the air into the mine, to install a local cooling equip- ment, and to place ice at the heading face.
