【摘要】：矿井温度异常将会导致矿井火灾和重大事故的发生,为此利用分布式光纤测温技术实现对矿井温度的在线监测和预警。通过室内实验装置对传感光缆的温度系数进行标定,同时把该测温系统布置在某矿区61101回风巷内,进行为期半个多月的在线监测,结果表明:利用该测温技术处理得到的温度变化曲线能准确反映巷道温度变化趋势,曲线上异常点区域可作为精准判断温度异常位置的依据;700 m长测线系统布置能够较好地适应现场环境,其获得的数据量丰富可靠,曲线特征明显。该测温技术定位精度高、运行可靠,且能适应长距离监测,满足矿井温度监测需要。
[Abstract]:The abnormal temperature of mine will lead to the occurrence of mine fire and serious accidents. Therefore, the distributed optical fiber temperature measurement technology is used to realize the on-line monitoring and early warning of mine temperature. The temperature coefficient of the sensing fiber cable is calibrated by an indoor experimental device, and the temperature measuring system is arranged in the 61101 return air lane of a mining area for on-line monitoring for more than half a month. The results show that the temperature change curve obtained by the temperature measurement technique can accurately reflect the change trend of tunnel temperature. The abnormal point area on the curve can be used as the basis for accurately judging the temperature anomaly position. The layout of the 700 m long measuring line system can adapt well to the field environment. The obtained data quantity is abundant and reliable, and the curve features are obvious. The temperature measurement technology has high positioning accuracy, reliable operation, and can meet the needs of long distance monitoring and mine temperature monitoring.
