Technology Research On Roadway Supporting Under The Conditions Of High Stress

The object of this study is tong-shun company (the tong-er mine)02812facesurrounding rock stress distribution, deformation of surrounding rock, and thesupporting scheme optimization and experimental roadway mine pressure observation,and the supporting effect appraisal, guidance of mine safety production. Through thedetailed study of the geological conditions, a thorough analysis of the support formtheory, numerical simulation results based on FLAC3Doptimization, put forward anchor,anchor cable supporting structure design method, calculates the top of roadway andlevel of two to help support parameters, and make the test roadway mine pressureobservation results.This topic through the various supporting theories, presents a design theory to theadaptability of coal roadway, to avoid blindly applies the theory, or on theoreticaldeviation of understanding, cause actual support failure. Anchor applied tofundamentally improve the supporting condition, guarantee the safety in production; thelabor intensity of workers is reduced, the working environment is improved; greatlyreduce support cost, improve the production of mine auxiliary transportation tension;improve the roadway cross-section of interest rate, reducing the roadway repairworkload, simplification of fully mechanized working face advanced support, to speedup the mining speed; improve the mining efficiency, promote the construction ofefficient, high yield of modern mine construction, obvious economic benefit, researchresults on Tong-shun company whole deep mining roadway played a key role in guiding,with significant technical and social benefits.
