摘要

Aimed at Yi'an Mine No.2 coal seam high gas content and poor coal seam permeability,combined with the actual conditions of the mine,using Flac3D software to establish corresponding numerical model to simulate the protective layer seam mining.Then based on the change of the stress and strain of the protective layer before and after mining,analyzed the relief effect,to provide a scientific basis for the actual production of coal seam mining.
