    • Abstract
  • According to the mechanism of coal and gas outburst, on the basis of a comprehensive analysis of through beds borehole orifice reasons and coal deformation in low permeability outburst coal seam, by using finite difference software FLAC3D and the related theories, the stress field distribution laws, displacement field distribution laws of coal body around drilling orifice are carried on numerical simulation, and stress field distribution and movement and deformation of coal around drilling orifice are obtained.
