Application Research of New Green Grouting Material in Water Conducting Structural Belt
With the extension of coal seam mining to the lower coal seam,water inrush disasters from the floor during coal mining seriously threaten the safety of coal mines and personnel's lives and property.Therefore,it is particularly important to use grouting materials to fill and reinforce the stable geological structure of coal mines.However,due to the problems of rough quality,low stability,poor water resistance,low solid strength,uncontrollable setting time,high cost,and serious pollution of traditional grouting materials such as ordinary Portland cement slurry,cement clay slurry,and chemical grouting materials,this paper proposes a new material mainly composed of burnt coal gangue and supplemented by a small amount of cement,and obtains a series of industrial comparison results,achieving good application effects.
