TBM-3D pre-exploration system with integration of rock-break epicenter and active epicenter

摘要

The present invention discloses a TBM 3D pre-exploration system incorporating rock-cut epicenter and active epicenter that integrates two active epicenter and rock-cut epicenter techniques to perform integrated 3D seismic pre-exploration. Before a drilling machine starts operation, the seismic method of active epicentres with higher impact energy is used to obtain the long-range exploration and geological anomaly position determination, and in the next steps to make drill drill regulation and optimization from the exploration results. During drill operation, lower impact energy rock fracture bit vibrations are used as an epicenter, and an uncommon seismic fracture epicenter data set processing technique provides more accurate, short distance, real time geological anomaly exploration and characterization and quality assessment of the surrounding rock in an excavating area. Based on the results of 3D seismic exploration with active epicenter integration and rock quarry epicenter, a comprehensive assessment of the geological situation in front of a work surface will then be made to assist in optimizing drill working parameters and building safety control.
