The challenge:

· Tunnel mining in an urban, densely populated area, at a shallow depth (a few meters under streets and roads) in a soil section consisting of heterogeneous fill.

Examining the quality of the mined material and determining engineering parameters for planning and optimizing the support solutions.

the solution:

· Carrying out a set of field tests and adapting them to the conditions and constraints in the field.

Crossing the information from the field investigation to the behavior of the tunnel, the monitoring results and the behavior of the mining fronts.
