SELECTION AND SUBSTANTIATION OF A FILL COMPOSITION MADE OF LOCAL RAW MATERIALS AT RUBTSOVSK POLYMETAL ORE DEPOSIT DEVELOPED BY THE SLICE MINING PROCESS, OAO SIBIR-POLIMETALLY URAL MINING-METALLURGICAL COMPANY
The block mining and consolidating stowing process is proposed. The horizontal and vertical stresses are evaluated. The average stowing strength values for the upper and lower layers are found. The procedure for the calculation of the characteristic strength for every mining level is developed. The stowing mixture composition made of local raw materials is substantiated for the slice mining conditions at Rubtsovsk polymetal ore deposit.
