摘要

Abstract

A mechanics model of coal pillar and backfill coupling function is established, the elastic solution of coal pillar and backfill coupling function is deduced by using Rize method, and analyze the effect which the depth of coal pillar on the displacement of coal pillar in two cases where filling and not. Then we get the laws of how the maximum horizontal displacement of coal pillar changes with the width of coal pillar and the modulus of elasticity of filling body changing. Simultaneously, we get the viscoelastic solution of coal pillar and backfill coupling function by Burgers riaeological models, and get two laws:changes in the maximum horizontal displacement with time ; changes in maximum horizontal displacement with width of coal pillar and the modulus of elasticity of filling body changing, which provide the reliable references for the design and research of filling roadway mining engineering.
