Claim 12:
13. The construction method of rock burst prewarning protection system in non-contact tunnel construction according to claim 6, wherein in Step III, when the increased normally moves, the thermosensitive infrared sensor and the highly sensitive laser sensor receive the signals, after multiple tests under different construction condition, storing the experimental data in the “surrounding rock mechanical parameter-rock burst critical deformation-rock burst critical temperature” database as a reference for signal filtering, filtering the signal collected by the highly sensitive laser sensor and thermosensitive infrared sensor in the moving process of the protecting trolley via mathematic function, eliminating the peak value of the deformation curve and the data, the variation of which significantly exceeds the reference value in “surrounding rock mechanical parameter-rock burst critical deformation-rock burst critical temperature” database.
