基于KJ26位移监测系统的8204~(-2)面巷道变形研究
|
摘要
本文以塔山矿8204~(-2)工作面为研究对象,采用光纤在线监测系统对8204工作面的巷道表面位移进行监测,现场测试结果表明,各传感器数据准确可靠、系统整体性能稳定,能够对巷道变形进行在线实时监测,为煤矿安全生产提供了可靠的数据支持。
In this paper, the 8204~(-2) working face of Tashan Mine is taken as the research object. The optical fiber online monitoring system is used to monitor the surface displacement of the roadway of the 8204 working face. The field test results show that the data of each sensor is accurate and reliable, the overall performance of the system is stable, and the deformation of the roadway can be performed. Online real-time monitoring provides reliable data support for coal mine safety production.
