Abstract: According to the technical problem of mine shaft lining breaking,water gushing seriously in shaft,many invalid sealing of using single liquid and dual fluid cement and sodium silicate in the deep and thick topsoil under complex hydrogeology conditions of Yiqiao coal mine,combining with the construction quality hypothesis and the vertical additional stress hypothesis of the mine shaft lining breaking theory,the water gushing characteristics and deformation failure mechanism of the main and auxiliary shaft were analyzed.And on this basis,grouting and blocking water gushing and reinforcement of surrounding rock mechanism of the high polymer chemistry material marithan N were studied,and the drill hole layout and the construction technology of grouting between borehole wall of topsoil section,grouting behind the wall of the bedrock section were formulated,and the process monitoring for the grouting quantity and grouting pressure were carried out.Through long-term monitoring of the shaft lining water gushing,the shaft lining water gushing was less than 0.05 m³/h,which realized the purpose of preventing and controlling of shaft lining water gushing,shaft lining breaking,stability of aquifer water pressure,and released and inhibited additional pressure of mine shaft-lining.
