Combining with the Meihuajing Coal Mine"s existing safety monitoring system power supply and actual layout of the roadway， the way of increasing the voltage level to 24V and reducing the cable resistance is proposed. And through the field practice research of xxxx working face ， the results show that this scheme has practical operating value ， the scheme is considered feasible ， simple and efficient. And the practical significance of long-distance power supply of safety monitoring system for mine safety production is discussed. 关键词：安全监控系统;远距离供电;解决方案;实践意义 0 引言 1下载后可任意编辑 梅花井煤矿安全监控系统与国内大部分矿井一致，主要采纳 18V 直流供电方式对传感器进行供电;当掘进工作面超过 20XXm 时，由于巷道内传感器较多，线缆压降导致迎头传感器无法全部拖动，需在巷道中部单独加装供电电源进行升压供电;遇到甲烷超限时，系统会将整个巷道内电源断掉，迎头传感器只能依靠巷道中部后备电源供电，由于距离过长，且电池供电能力有限，存在安全运行风险[1]。 1 现状分析...
