  • A new technique and method for non destructive test of anchoring quality of rock bolts is introduced. By the simulation test in laboratory, the features of reflective phase and energetic attenuation of sonic frequency stress wave in the anchoring system are analysed, and the determination of anchoring force in non destructive drawing test is described. The results are successfully applied to the construction quality test of anchoring engineering in the First Coal Mine of Panji.
