Propagation of pendulum waves under deep-seated cord charge blasting in blocky rock mass (1811.03900v1)
Published 9 Nov 2018 in physics.geo-ph and physics.class-ph
Abstract: The object of the numerical study is the travel of pendulum waves in a blocky medium under nonstationary impact of deep-seated charge blasting on the surface of the expansion chamber. The blocky model is simulated by a two-dimensional lattice of masses connected by elastic springs along the axes and diagonals. The displacements and velocities of the masses at different half-space points are calculated using the finite-difference method.
