| Abstract: | Strength of backfill is an important parameter in the backfilling mining method.The paper introduces the self-stable conditions of backfill.With tailings cemented backfill in Jiaojia gold mine as example,analysis is carried out on the influencing factors of self-stable strength.The requirements of slurry concentration and proportion are determined.Meanwhile,the strength of backfill should be larger than 2.0 MPa.The research provides theoretical references for mining production safety. |
