Hi everyone.

I have the following question:

Which software is better to see the influence of the mining process in a neighbour tunnel? with FLAC/FLAC3D, UDEC/3DEC or Blo-up?

The objective is evaluate the stresses into the support of the tunnel due to the blasting in the vicinity. thanks in advance
