Abstract
In order to study how different factors influence the mine pressure regularity of the 30108 working face, this article makes use of 3DEC software to analyze the situation of the roof s damage in the mining process of the fully-mechanized face in Yanghuopan colliery, based on on-site mine pressure, and also uses FLAC3D simulation software to simulate mine pressure behavior law. The result of a-nalysis shows that the caving property of coal seam is comparatively well, basic roof pressure appears obviously , the stress arch structure formed in superincumbent stratum can slow down the effect of the extraction space caused by the synchronous sinking motion of the incompact surface and the bedrock layer.关键词
