LOOSE ROCK DETECTOR |
摘要 |
A loose rock detector comprises an impact tool for hitting the rock face, sensors for detecting acoustic, rock motion and/or impact force signals generated by movement of the impact tool against the face of the rock, a data processor responsive to the sensors for correlating the above signals in the time and/or frequency domain against predetermined relationships to detect loose rocks and to assess mass and degree of looseness of the rock, and a display unit for displaying the results of the correlation.
