摘　　要：根据采空区自然发火的特点,介绍了基于拉曼散射的分布式光纤测温原理及系统的构成,在实际现场采用沿工作面走向"W"形布置多条光纤的新技术,现场应用表明:该技术能够对采空区温度进行网点式监测,提高了监测的有效范围和准确度。According to gob spontaneous combustion characteristics,introduced the principle and the system composition of the distribu- ted fiber temperature measurement based on Raman scattering and put forward a new concrete implementation method of the application of distributed fiber temperature measurement system in the coal mine gob fire prevention and control, that is arranging a few ＂ W＂ shaped optical fibers along the direction of the working face. On-site application shows that ： the technology can realize network type mo- nitoring on gob temperature, and it can increase the effective range and the accuracy of monitoring either.
