【摘要】：基于综放采空区自然发火隐蔽高温区难以识别的问题,提出了分布式光纤温度探测技术监测火源高温点以及井下近距离抽气束管探测技术监测气体异常点。根据综放工作面采空区遗煤分布特征及漏风规律,布置符合现场实际情况的温度及气体测点,现场研究了采空区内不同时期分布式光纤测温监测的温度,通过三维绘图软件绘制出采空区温度场分布规律,研究了采空区内O_2及CO分布情况。结果表明:光纤测温结合近距离束管抽气的监测结果符合煤氧复合机理及采空区漏风规律。
[Abstract]:Based on the problem that it is difficult to identify the spontaneous combustion covert high temperature area in fully mechanized caving area, the distributed optical fiber temperature detection technology is proposed to monitor the high temperature point of the fire source and the technology of detecting the gas anomaly by the short distance pumping tube in the underground. According to the distribution characteristics and air leakage law of coal in goaf of fully mechanized caving face, the temperature and gas measuring points which accord with the actual situation in the field are arranged, and the temperature of distributed optical fiber temperature monitoring in different periods in goaf is studied on the spot. The distribution law of temperature field in goaf was plotted by 3D drawing software, and the distribution of O _ 2 and CO in goaf was studied. The results show that the monitoring results of optical fiber temperature measurement combined with short distance beam tube air extraction accord with the compound mechanism of coal and oxygen and the rule of air leakage in goaf.
