Advanced Predication of Geological anomalous Body Ahead of Laneway Using Seismic Tomography Technique

摘要：

　　Advanced predication of geological anomalous body (GAB) of laneway can provide scientific references for mine safety production.It refers to reveal the position,shape and size of GAB in advance.Seismic tomography technology (STT) can realize the prediction of GAB using tunnel surface waves.Tunnel Reflection Tomography (TRT) 6000 system,which is on the basis of STT,has the advantages of convenience and high reliability.In this paper,TRT6000 is introduced to forecast the GAB ahead of laneway in underground metal mine.The operation steps,data processing and notes about TRT6000 are detailed.The research results show that there are two water flowing fractures,separately located at around 50meters and 85meters ahead of laneway.And the prediction results match the actual situation well.Therefore,the seismic tomography technology improves the mine safety management,and the TRT6000 provides a new method for predicting GAB in advance.
