Mine Roof Bolt Bond Tester
This citation summarizes a one-page announcement of technology available for utilization. A unique, intrinsically safe, electronic instrument has been developed that determines the holding quality of a fully grouted roof bolt by testing the integrity of the resin bond to both the bolt and to the surrounding rock. A measured pulse of energy is sent into the bolt by a piezoelectric transducer, and the instrument listens for reflected energy. ...FOR ADDITIONAL INFORMATION: Contact: Technology Transfer Officer, U.S. Bureau of Mines, Denver Research Center, Bldg. 20, Denver Federal Center, Denver, Colorado 80225.
