针对葛亭煤矿倾角大、厚度大和强自然发火倾向的3#煤层,通过预埋光纤光栅传感器,采用光纤光栅传感系统,对采空区进行长距离温度实时在线监测,绘制出采空区内温度分布曲线,研究该矿3#煤层大倾角综放工作面自然发火规律。
Aimed at the coal seam # 3 seam with large dip angle, large thickness and strong spontaneous combustion tendency in Genting Coal Mine, the fiberglass sensor system was used to monitor the mined-out area for long-distance temperature in real time through the embedded fiber grating sensor. Temperature distribution curve to study the law of spontaneous combustion in the fully mechanized top coal caving face with seam 3 # in this mine.
