Classification of Rock Bursts

Soviet mining science, 1986
The authors provide classification criteria for rock bursts based primarily on three features: the location of the focal zone of a rock burst relative to the mine; the reciprocal interaction of a rock burst and the existing tectonic structure in the part of the bed experiencing the rock burst; and the distribution of rock bursts according to the energy

Mechanisms of rock burst in hard and thick upper strata and rock-burst controlling technology

Arabian Journal of Geosciences, 2016
Rock burst frequently occurs during coal mining at the Huafeng Coal Mine because of the high-strength, thick conglomerate strata above the coal seam. Given this situation, theoretical analysis, physical simulation, and field measurement methods were applied to study the mechanism of rock burst of hard and thick upper strata in this paper.

Numerical simulation of rock bursts

International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1991
Abstract The mathematical description of dynamic fracture processes, in particular of rock bursts in hardcoal mining, can be advanced by the use of dynamic iterative methods. From a comparison of two different numerical approaches the dynamic finite difference method as used in the FLAC program turned out to be the most suitable.
