Hydraulic Sandfill in Deep Metal Mines.
NTIS: PB 241 194 :63 pages
The Bureau of Mines and industry (mining and private) have studied the placement of hydraulic sandfill in deep-vein mines to identify existing problems and to develop techniques to strengthen the support characteristics of the sandfill. The hydraulic sandfill system, physical properties of typical classified mill tailings, and properties of sandfill modified by various techniques are discussed. Computer analysis has defined the support capability of various sandfills using actual mine field data as a reference base. High- modulus sandfill can provide adequate support in deep-vein mines to alleviate rock and pillar stresses and to reduce rock-burst incidence. (Out of print.)
