摘　　要：由于煤矿井下作业场所的特殊性,电缆着火引发的重大事故会严重威胁煤矿的安全生产,介绍了煤矿井下电缆火灾事故的主要原因和特点,提出了基于拉曼散射的光纤测温技术对井下电缆温度进行实时监测预警,并给出了分布式光纤测温系统的原理、硬件组成。As the special nature of coal mine work areas, major accidents caused by cable fire would seriously threaten the safety of coal production. This article described the main reasons and characteristics of the cable fire, a system of fiber optic temperature measurement based on Raman scattering was introduced to monitor the coal mine cable temperature, the principle of distributed fiber optic temperature measurement system and the hardware components were given in this paper.
