摘要:

副立井提升系统的安全运行对煤矿生产至关重要,传统监测方法存在主观性强、监测范围有限等不足。针对这一问题,研究分布式光纤侦听技术在副立井提升系统中的应用,分析了光纤中瑞利散射、布里渊散射和拉曼散射的原理,并深入介绍了瑞利散射在声音振动监测中的应用。通过相干瑞利散射的分布式光纤传感器(DAS)实现了振动信号的检测与定位。通过构建模拟实验平台与矿井实测场景的双重验证体系,证明系统能捕获常见异常状态造成的振动和声波。该技术能有效监测罐笼运行状态,振动产生的相位偏移与速度、负载呈正相关,系统可靠性高,为副立井提升系统安全监测提供了新方案。

Abstract:

The safe operation of the auxiliary shaft hoisting system is crucial for coal mine production. However, traditional monitoring methods suffer from limitations such as strong subjectivity and limited monitoring coverage. Under this under this circumstances, we explored the application of distributed optical fiber sense technology in the auxiliary shaft hoisting system, analyzed the principle of Rayleigh scattering, Brillouin scattering and Raman scattering in optical fiber, and introduced the application of Rayleigh scattering in sound vibration monitoring. The distributed optical fiber sensor (DAS) based on coherent Rayleigh scattering was used to detect and locate the vibration signal. By constructing a dual verification system of simulation experiment platform and mine measured scene, it was proved that the system can capture the vibration and sound waves caused by regular abnormal states. The technology can effectively monitor the running state of the cage. The phase shift generated by the vibration is positively correlated with the speed and load, and the system reliability is high, which provides a new scheme for the safety monitoring for auxiliary shaft hoisting systems.
