Application of Distributed Optical Fiber Sensor in the Monitoring of Mines Rockfall

摘要：

For the unfavourable exploitation environment of Gold Mine in Shandong Province, the anchor is used as the sensing agent of the optical fiber sensor. By monitoring the strain of anchor to reflect the tendency of the rock strain, the rockfall in the exploitation area is monitored to some extent. The indoor static test, the numerical simulation of the rockfall in site by FLAC<’3D>, the static and dynamic test in the practical site are used to check the rationality, as well as the practicability of the analysis and monitoring method. All of these provide some experience and foundation to prove the monitoring of the rockfall in exploitation area.
