Deep radioactive waste deposits require specific solutions to close underground galleries and avoid any radioactive migration in the environment. One investigated solution consists of a swelling clay plug that induces a swelling pressure of approximately 7MPa on the walls of the galleries. The clay plug is confined by a concrete plug to maintain and drive the swelling pressure towards the walls of...
Longwall mining is the most profitable and safe coal extraction method from deep seated deposits. Understanding the interaction between powered supports, surrounding rock and coal strata is the key for successful operation. In this respect, numerical modelling techniques provide great insight into the behaviour of shield support especially loading behaviour of hydraulic leg and canopy under different...
