Face destressing blast design for hard rock tunnelling at great depth
Destress blasting of development headings is a construction technique in deep tunnels, whereby explosives are used to fracture the rock in such a way that strain energy is dissipated from the rock mass, with minimal deformation. This is intended to reduce the frequency and severity of violent stress...
