Slow compaction due to low fragmentation rates lead to excess pore pressure Pg* < 0.2 (Pg* = Pg/normal stress) even for ... WebDec 21, 2024 · Thus, the compaction characteristics of crushed waste rocks (CWRs) are a key factor influencing the backfill effect of goaf [16,17]. If a certain lateral pressure is applied to CWRs backfilling goaf, the density and deformation resistance of CWRs can be improved . Additionally, the number of lateral loading cycles influences the compaction ...
