Abstract
12209 working face of a coal mine is isolated island working face, and both side of working face is goaf. In this paper, In this paper, FLAC 3D is used to simulate the stress concentration caused by mining of adjacent working face. The width of coal pillar is calculated, and the optimum position of the tunnel is simulated. and numerical simulation leads to the vertical stress distribution on the coal pillar and the optimum position of the tunnel is determined. Reserved coal pillar made the roadway small deformation and maintain the stability of the roadway.关键词
