Compaction Characteristics and Application of Solid Filling Material

In view of the present widely used five solid filling materials, we design experiment schemes, study the compaction characteristics, and conclude that stress-strain, stress-density and compaction constitutive characteristics under the condition of lateral confined compression, which provides the basic data for controlling strata and ground surface deformation by solid filling mining technology; based on the compaction characteristics, we formulate five kinds of solid material filling mining technique: compaction force design index and mass ratio, it provides guidance for different mineral fields in the selection of solid filling materials.
