1. 995m 3 /h for BFR. (5) The optimization results are expected to reduce cement consumption by about 4,685 tons, increase tailings consumption by about 2,642m 3 , save cost by about 1,803,805 RMB, and reduce CO 2 emission by about 4,685 tons per year. Optimizing the CPB ratio and self-flowing transportation parameters with UCS and FR as dual-response values provides a novel idea for optimizing backfill parameters and reducing costs;CRediT authorship contribution statement Chunakng Liu: Writing -original draft, Writing -review & editing, Conceptualization, Software, Methodology.
