Abstract: Aiming at the problems of poor performance of super high-water material, low filling density and complicated filling system, the super high-water material filling and mining in Tianzhuang coal mine is taken as the research background.The effects of different admixtures on super high-water material are studied.The creep properties of super high-water materials are analyzed, the filling system and process are improved, and meanwhile, industrial tests and effects analysis are carried out.The results show that with the increase of AA admixture content, the slurry flow performance is worse, the bleeding rate is reduced, the uniaxial compressive strength is gradually increased, compressive strength can reach up to 0.90 MPa after 28 days;The strain of super high-water material closed under the pressure of 6.5 MPa is only 6.02×10^-3, and super high-water material can be regarded as an incompressible body;the filling process system is simple, efficient and stable, and realizes the precise automatic operation and the process of semi-continuous pulping and continuous slurrying, which satisfies the rapid recovery and filling of the working face;with good performance of super high-water material, high compactness of filling body and complete contacting between filling body and roof, remarkable control effect of surface subsidence is achieved, resulting in green mining of coal resources.
