Abstract:

Collapse or roof fall usually occurs at the open cut part. To solve this problem, comprehensive geological prediction is necessary.The basic principles of two widely used geological prediction methods (TSP and GPR) were introduced. These two methods were applied in detection of an opencut tunnel. The basic position of the gully and the water cut condition were determined according to  advanced geology prediction using TSP203. An opposite conclusion was  obtained that opencut tunnel would not show here. In addition, the thickness of bedrock was tracking detected using GPR, and a comparasion with the excavation was given.

Key words: TSP; GPR; opencut tunnel; comprehensive geological prediction
