Abstract: In order to obtain more accurate statistical results when carrying out the data analysis of rock structure by using Sirovision telemetry system of jointed rock mass，firstly，the process of filed measurement and data analysis of the system are studied，and the equipment composition and working principle of the system are introduced.Main source of the errors in the process of investigating and analyzing the jointed rock mass by using the system is analyzed.The errors can be summarized as the error of shooting operation，the error of control point coordinates and the error of joints identification；then，according to the different sources of errors，the corresponding error calibration experiments are carried out so as to analyze the causes of errors generated and the influence of the errors on investigation and analysis results.Effective measures of reducing errors are proposed to correct the investigation and analysis results；finally，rock structure of the typical rock of Jiaojia gold mine is investigated and analyzed based on the corrected Sirovision jointed rock mass investigation and analysis method，and the three-dimensional model of rock mass is reconstructed and the information of the structure surface is extracted.Comparison between the investigation and analysis results of the Sirovision system and the manual measurement results are conducted，and the results show that the data obtained by the corrected Sirovision jointed rock mass investigated and analysis method is consistent with the actual situation，it can meet the precision requirements of jointed rock mass investigation.The unstable structure (wedge structure) of Jiaojia gold mine is analyzed based on the spatial distribution pattern obtained by the corrected Sirovision jointed rock mass investigation and analysis method proposed in this paper.It can provide some reference for stability of rock mass classification and ensuring mine safety production.
