光纤测温系统在煤矿自燃预测预报中的应用

Application of Optical Fiber Temperature Measurement System in the Forecasting of Coal Mine Spontaneous Combustion

煤矿常用采空区测温方法为近采空区测定温度或者通过布置温度传感器进行测量,此方法测量误差大,导致高温点定位不准确。为解决上述问题,济宁三号煤矿采用了光纤测温系统,通过在采空区丢煤区域预埋测温光纤,较好地解决了以往测温方式的缺陷,能够准确定位采空区高温点,为煤矿防灭火提供数据支撑。

In coal mine, the temperature measurement method of the goaf area is used to measure the temperature in the near-goaf area or to measure it by deploying temperature sensors. These methods have large measurement errors, resulting in inaccurate positioning of high temperature points. In order to solve the above problems, Jining No. 3 Coal Mine adopted a fiber optic temperature measurement system. By pre-burying the temperature measurement fiber in the coal mining area, it has better overcome the defects of the previous temperature measurement method and can accurately locate the high temperature points in the mining area., provide data support for coal mine fire prevention.
