| Abstract: | The relation between rupture of auxiliary shaft and hydrogeological conditions of bottom aquifer in Quaternary system is discussed from hydrodynamic and hydrochemical conditions in Kongzhuang colliery of Datun in the paper. The influences of the change of hydrogeological conditions on forcing state and strength characteristic of auxiliary shaft,bottom aquifer, and its surrounding rock-soil mass are analyzed in detail. An importance of hydrodynamic change in analysis of outer stress environment for the shaft and dormage from hydrochemical corrosion which has effect on strength of shaft lining concrete are first put forward. |
