Numerical analysis of stress distribution of isolated working face in undergrourd mining area
摘要
Abstract
The paper utilizes Finite Difference Method software FLAC-3D for simulation analysis to get the discipline of stress distribution discipline of isolated island working face. The coal pillars on the isolated island working face bear the gravity of overlying strata layer of isolated island working face, in the status of stress concentration ; the front of the working face forms the stress reduced area, stress increases area, protolith stress area, coal and rock stress concentration coefficient increases constantly, while the isolated island working face moving forward. The study provides parameter data for the development of anti-red and outburst prevention measures, and it also has important application value for guiding the on-site production关键词
