摘 要: 通过对测温热电偶的实验室标定和工作面标定,得到所用热电偶的冷热端的温度变化与产生的电压之间的线性关系。通过观测采空区温度的变化以及数据处理,对工作面采空区温度变化规律进行了具体的分析,从而对屯兰矿12407工作面采空区"三带"进行了划分。 Through the calibration of the thermocouple in laboratory and working face, getting the linear relationship between the temperature change of the thermocouple cold end and the voltage. According to the observation and data processing of goaf temperature variation, variation of temperature of air mining face is analyzed, thus the 12407 working face gob of Tunlan coal mine "three zones" are divided.
