基于TRT技术的井下地质超前预报

RT technology is one of advanced prediction technologies based on the seismic method. It is an effective approach to solve advanced prediction of tunnel owing to seismic migration and space imaging technology. The operational principle, operation method and application in mines are introduced. The TRT6000 system was used in Tongkeng Mine of Dachang. The results of advanced predication with practical engineering show that TRT is proper for advanced prediction under complex condition in underground with advantages of simple operation and little interference. It provides important information for mining and safety control according to effectively analyze and judge on the crushed zone, stope and caving area beyond tunnel face. Finally, matters need attention of operation, deficiencies and improvement of TRT system in mine are analyzed
