The study on the new technique and technology of consolidated filling with pumped alumina plant waste which was undertaken by Chansha Institute of Mining Research and Shandong Aluminium Industry Incorp,created a precedent for the consolidated filling without cement, solved successfully the difficult problems on the mining method used for Hutian bauxite mine, eliminated the surface subsidence and protected the natural environment. Meanwhile, this study reduced the cost of filling considerably ,alleviated essentially the pollution of fill to underground drifts and opened the new way to the utilization of industrial waste materials for Shandong Alluminium Industry Incorp. The authors make an introduction to characteristics of the alumina-plant wast(consolidated filling matenals),preparation of filling materials,pumping technology,and the pilot test for inclined slicing filling and its results.
