煤矿井下避难硐室供电系统设计浅析

Elementary Analysis of Power Supply System Design for Underground Refuge Chamber in Coal Mines

煤矿井下避难硐室是具有紧急避险功能的专用巷道硐室,为井下矿工提供延续生命的空间,提高煤矿安全保障能力。避难硐室分为永久避难硐室和临时避难硐室两种。通过几个设计实例,对不同矿井避难硐室设置位置、容量及设施配置或同一矿井不同位置的避难硐室设置进行分析,并设计不同的供电方案,以期提高煤矿井下避难硐室的可靠性。

The underground refuge chamber in coal mines is a special tunnel chamber with the function of emergency avoidance,which can provide space for prolonging survival for underground miners and improve the safety guarantee ability of coal mine.Refuge chamber is divided into two types：permanent refuge chamber and temporary refuge chamber.Through several design examples,this paper analyzed the location,capacity and facilities configuration of refuge chambers in different mines,and the arrangement of refuge chambers at different locations in the same mine and designed different power supply schemes to improve the reliability of refuge chamber in the underground coal mine.
