INVESTIGATION ON SUPPORTING STRUCTURE DESIGN AND STABILITY ANALYSIS OF COAL ROADWAY BASED ON NUMERICAL SIMULATION

By the coal roadway supporting engineering in Shanxi province,based on the theory of composite beam theory and suspension theory,applied with FLAC-3D numerical simulation,merged the engineering analogy method,numerical simulation and monitor design method,optimized the supporting design schemed,at last the paper obtained the reasonable supporting scheme.Applied these theories to the practical engineering,the results indicate it's effectiveness.This theme is of great importance in coal roadway supporting design.
