Abstract:
By setting up symmetry laminate model of surrounding rock deformation in solid-stowing mining and presenting definite condition,analytical solution of surrounding rock deformation was obtained.Applying FLAC to building up numerical simulation of stowing mining model,the influence of stowing body's dense,mining height and mining depth on surrounding rock deformation was researched.Results showed that influence of mining height and depth on surrounding rock deformation took on linear relationship.The influence of stowing body's dense on surrounding rock deformation was more obvious.When dense
η< 75%,deformation was large,and when it was minor than 75%,deformation largely reduced.Research result could provide reference for solid stowing mining theory and technique design.
