Abstract:
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.
