Actual measurement and analysis on deformation characteristics of fault structure under mining condition
Influenced by mining, the fault structure in the surrounding rock of stope will generate the corresponding activation effect.In the article, combining with the geological conditions of a mining face in Huainan,a suit of drilling testing system using distributed optical fiber sensor technology was set up to monitor the formation deformation of the FS2 fault in real time, and the continuous observation data of the test space rock mass were obtained.The analysis shows that the strain mutative characteristics of strata near the structural plane of the fault caused by the mining are remarkable are outstanding, and it proves further the possibility of induced activation in the fault.Fiber optic sensing test technology can provide a large amount of data with high precision,which can provide reference for the study of deformation characteristics of fault structure.At the same time,the numerical simulation method was used to simulate the deformation and failure of faults.The results between simulation and testing were in good agreement with each other.
