Tunnel Seismic Prediction (TSP)

Tunnel Seismic Prediction (TSP) Cost saving benefits TSP 303 – the world’s most successful seismic prediction system – comprises the wealth of more than 20 years of experience in Tunnel Seismic Prediction. Specially designed for underground construction, TSP 303’s outstanding advantages help you stay ahead of your project objectives.

The TSP 303 method

TSP 303 evaluates seismic echo signals reflected from changes in the elastic rock characteristics associated with discontinuities in the rock mass.

The TSP 303 characteristics

TSP 303 offers to all conventional tunnelling and Gripper & Shield TBM heading advanced geological prediction with an investigation range up to 200 m from face to meet your daily operational needs:
