What is it about?
To understand the evolution of pore water pressure and stresses in backfilled stopes for barricade design. Emphasis was given on the pressures and total stresses on the barricades in underground mine backfilled stopes. The influence of several parameters on the evolution of the pore water pressure and total stresses was analyzed by numerical modeling.

Why is it important?
The pore water pressure and total stresses during and shortly after the filling operation are the key parameters in barricade design. Draining holes are commonly used with impervious barricades (sometimes called "bulkheads"). Our numerical results show that the draining holes are effective in reducing the pore water pressure, but not very effective in reducing the total stresses in "short-term".
Perspectives
I hope this article be useful to the reader in understanding the important aspects and factors to be considered in barricade design.
