Influence of backfilling rate on the stability of the “backfilling body-immediate roof” cooperative bearing structure

To reduce the cost of backfilling coal mining and utilize the underground space of coal mines, a new backfilling mining method with low backfilling rate called constructional backfilling coal mining (CBCM) is proposed. The “backfilling body-immediate roof” cooperative bearing structure of CBCM is an...
