Abstract
The proportion of gob coal spontaneous is about 70% in mine fire.More than 50% of state-owned coalmine exist the danger of coal fire.So online monitoring of temperature is very important.A temperature sensor is used in the coal mine tunnel.The sensor principle is that temperature change is transited into fiber Bragg grating wavelength shift.According to Zhu Xian coal mine tunnel coal distribution and diffusion characteristics,at the top of coal mine tunnel,every 2mlong,intrinsically safe distributed fiber Bragg grating temperature sensors are installed along the roadway direction.A real-time temperature monitoring of the area is achieved.

期刊介绍：
The predecessor of Optical Technology was Optical Technology, which was founded in 1975. At that time, the Fifth Ministry of Machine Building entrusted the School of Optoelectronics of Beijing Institute of Technology to publish the journal, and it was officially approved by the State Administration of Press, Publication, Radio, Film and Television for external distribution. From 1975 to 1979, the magazine was named Optical Technology, a quarterly with 4 issues per year; from 1980 to the present, the magazine is named Optical Technology, a bimonthly with 6 issues per year, published on the 20th of odd months.
The publication policy is: to serve the national economic construction, implement the development of the national economy, serve production and scientific research, and implement the publication policy of "letting a hundred flowers bloom and a hundred schools of thought contend".
