(Research project: BMBF ministry “Deponieuntergrund”)


1999   First horizontal boreholes with the optical borehole scanner on the Alp Transit project

(Monte Ceneri Base Tunnel, Switzerland)


1999   First horizontal boreholes underground at Lötschbergtunnel using special pushing rods and adaptor to the drill string in holes with 200m length.
