compaction qualities of crushed rock · Crushed waste rock can be used as backfill in goafs to allow reuse of otherwise solid waste and to control surface subsidence. If a certain lateral stress is applied to crushed waste rocks beforehand, they are densified. Therefore, this research investigated the effects of lateral stress on compaction characteristics of waste rocks for backfilling by utilising a selfdesigned bidirectional
compaction qualities of crushed rockRecycling of crushed waste rock as backfilling material in . Abstract. Crushed waste rocks can be used as materials for backfilling goafs, so as to achieve the simultaneous goals of processing solid waste and controlling surface subsidence; however, particle size distribution directly affects the compaction of crushed waste rocks.
Soil Compaction HandbookSOIL COMPACTION HANDBOOK 3 What is soil? Soil is formed in place or deposited by various forces of nature— such as glaciers, wind, lakes and rivers—residually or organically. Following are important elements in soil compaction: Soil type Soil moisture content Compaction effort required Why compact? There are five principle reasons to compact soil: Increases loadbearing capacity Prevents ...
