Abstract :
Length is an important factor to evaluate the quality of rock bolts. Due to the harsh environment and large amounts of noise contained by rock signals detection, it´s difficult to estimate the rock bolts parameters. In this paper, a non-destructive testing(NDT) method is used to detect the parameters of free bolt. Six different types of excitation signal is used on rock bolts, the reflection signal is detected respectively by ultrasonic sensor, which is analysed by a fusion algorithm of D-S evidence theory, the result shows that this method is satisfied.
