Abstract
The mine a protection layer surface for prototype experiments, using FLAC 3D numerical simulation software, analysis and study of the protective layer working face mining design with different coal pillar width, protected coal seam stress vertical variations. According to the analysis of vertical should force changes in the law, judgment is the protection layer of gas pressure relief effect, can working face layout optimization and pressure relief gas drainage to provide the basis, for other conditions similar to also have certain reference signiifcance.关键词
