摘要

PROBLEM TO BE SOLVED: To detect the collapse of rock beforehand by quantitatively evaluating the collapse possibility of rock on the basis of the signals detected by a plurality of measuring sensors arranged in a monitor area. ;SOLUTION: Outputs are always automatically emitted from a plurality of attached AE sensors 61 at every definite time to monitor the collapse of rock and the presence of the fluctuations of sensor outputs is investigated. Next, when the fluctuations are confirmed, the discrimination of the correlation with respective AE sensor outputs and time delay with a vehicle passage signal is performed by a personal computer 65 while the moving speed of a passing vehicle is referred to by a preliminarily formed signal transmission characteristic data base 67 and a laser Doppler speedometer 66. Succeedingly, when it is confirmed that the detected fluctuation signal is a signal showing the signals of collapse, a signal generating position is automatically estimated in consideration of the positional relation of the measuring AE sensor 61 near to a place where a detection signal is detected to estimate the position of collapse.;COPYRIGHT: (C)1997,JPO
