Abstract

Stress concentration caused by deep strip-pillar mining will give rise to rockburst. Mining and retaining parameters have a major influence on stability of coal pillar. Ideally, FLAC3D was used to analyze the distribution and evolution of vertical stress, deformation, advanced abutment pressure and elastic strain energy density under the conditions of different mining and retaining which determined the scope of the dangerous zone ahead the mining face, and basis was provided for rockburst prevention in deep strip-pillar mining.
