Study on Numerical Analysis on Floor Heave Control of Mine Roadway with Soft and Weaken Surrounding Rock in 1 000 m Deep Mine
M I Wen-chuan
Abstract：In combination with the actual engineering of the mine roadway in Zhaolou Mine ,the paper analyzed the floor heave control mechanism of the mine roadway .The UDEC numerical analysis soft-ware was applied to the numerical simulation analysis .An optimized method to control the floor heave of the mine roadway was obtained .The numerical simulation and site observation showed that the ap-plication of the bolt and cable support reinforcement and the borehole pressure releasing combined method could effectively control the deformation of the mine roadway ,could make the floor in the stress reduced zone ,could improve the stability of the floor strata and could be an effective measure to prevent and control the floor heave .
