Method of acting remotely in a mine shaft, in particular in a site for deep storage of nuclear wastes

摘要

A method of remote control of a mobile carriage including at least one transmit and receive antenna for movement into an underground gallery connected to the surface by a shaft provided with an elevator for effecting deep storage of radioactive wastes. The method involves fitting the site with a plurality of waveguides from a control station which includes a signal generator and a signal receiver and being situated on the surface. The plurality of waveguides are disposed with at least one first waveguide at the surface extending from the control station to the entrance to the shaft. At least one second waveguide is disposed along the shaft and connected at its top end to the first waveguide. At least one third waveguide is disposed along the gallery and connected to the second waveguide in the vicinity of the entrance to the gallery. The waveguides are designed for remote tracking of the robot carriage and for controlling the elevator and at least one robot carriage carried by the elevator during vertical descent and ascent of the elevator within the shaft, and for controlling lateral movement of the robot carriage from the elevator into and within the gallery.
