摘要
Abstract
Through the establishment of physical model,using FLAC3Dsoftware to simulate hydraulic flushing,the results show that the stress peak of hydraulic flushing transfers to the deep parts and the coal pressure gets relief.Then through the punching simulation of different diameter,different buried depth,different thickness of coal seam,the vertical stress and displacement distribution laws under different conditions are summed up.关键词
