A major problem for the driving of a tunnel is the knowledge of the geological environment and its geotechnical parameters. The horizontal core drilling is used to find the hardness of the rock mass and weak zone near the excavation face. But the horizontal core drilling takes long time and a lot of money. In addition, The prediction of the horizontal drilling is less than 50m, It has an uncertainty. Tunnel Seismic Prediction(TSP) method is possible to predict the maximum 200m and prediction ahead minimize the downtime risk of expensive tunnelling equipment. This study has a purpose to check the accuracy of the predicting unfavorable ground conditions such as fault, fractured zone and rock quality variation zone ahead of the tunnel face using 3D-Velocity based Migration and Reflector extraction technology 3D TSP survey equipment and check the accuracy by comparing the observed Face mapping result.
