摘　　要：对于煤矿生产作业来说,安全是永恒不变的主题。矿井内的照明和排气等安防设施的正常工作离不开供电系统的稳定运行,一旦系统保护出现故障,将导致大规模停电,严重危害煤矿作业的安全。随着社会的发展和人们对生命财产安全的重视,当下煤矿供电系统中常用的几种防护方案逐步显现出了它们的局限性,而纵联差动的电学原理通过将电学原理与信息技术相结合,可以很好地规避这些局限性。因此,从该技术的原理着手,结合其在矿井供电系统中的具体应用对其进行分析,并对其实用性展开阐述。For coal mine production,safety is an eternal theme,and the normal work of lighting and exhaust and other security facilities in the mine is inseparable from the stable operation of the power supply system.Once the system protection barrier leads to large-scale power failure,it will cause serious harm to the safety production.With the development of society and people’s attention to the safety of life and property,several protection schemes commonly used in coal mine power supply system gradually show their limitations.However,the electrical principle of longitudinal differential can avoid these limitations,which can be effectively solved by combining electrical principle with information technology.This paper will start from the principle of the technology,combined with its specific application in the mine power supply system to analyze this technology,and its practical applicability.
