he mechanics reserarch of coal pillar and backfill coupling function
建立了煤柱与充填体耦合作用的力学模型，应用Rits法解出了煤柱与充填体耦合作用的弹性解，分析了在充填与不充填情况下煤柱宽度对煤柱位移的影响，得到了煤柱位移随着煤柱宽度变化规律。应用Burgers流变模型，求出了煤柱与充填体耦合作用的粘弹性解，分析了在充填与不充填情况下煤柱宽度对煤柱位移稳定时间的影响，得到了不同煤柱宽度时煤柱位移随时间的变化规律。
Establishment the mechanical coupling model of a coal pillar with backfill, Use the Rize method to solve elastic solution of the model and analyse the influence of the pillar width to the pillar displacemen in case of filling and not filling, obtained the change rule of the coal displacement along with the coal width;Use the Boggs constitutive model, get the pillar and filling viscoelastic solution of coupled model and analysed the influence of the pillar width to the pillar displacemen stable time in case of filling and not filling, obtained the change rule of the coal displacement stable time along with the coal width.
