Application Research of Optical Fiber Grating Sensor Technology Used in Mining Area Ground Fracture Monitoring

摘要

In this paper, We through to analysis the slope deformation and ground cracks caused by mining, we selected Hunan Lengshuijiang Xikuangshan antimony ore district, Chongqing Nantong coal mining area as the real-time monitoring, made a real-time monitoring scheme, laid the grating sensors, monitored the real-time monitoring, to obtain the effective monitoring data and carried on the comprehensive analysis, implementation of the real-time online monitoring of mining area ground deformation, structures of cracks. Through the application tests, we analysis that real-time monitoring techniques have enormous potential in the mining area ground crack monitoring.
