Tunnels and seismic waves
2003/11/01 Elhuyar Zientzia Iturria: Elhuyar aldizkaria
They have developed a new method based on seismic waves to see what lies behind the faces of the tunnels. From one side of the tunnel, seismic waves are emitted, warning us of possible significant fractures in rocks or earth mass. The transmitter adapted to the drilling machine emits sound and the microphone receives these sound waves. All these geological features are controlled with a computer.
