Abstract: Abstract The ultrafine-tailings cemented paste backfill (UCPB) exhibits special rheological characteristics in the high-temperature underground mining environment, which has an important influence on the stability of pipeline transportation. This study examines the time- and temperature-dependent… read more here.

DOI: 10.1016/j.powtec.2020.12.035
Abstract: Abstract To improve the flowability of ultrafine-tailings cemented paste backfill (UTCPB) while keeping water content low, superplasticizers (SP) are usually used. The water film thickness (WFT) theory was introduced to investigate the flowability of UTCPB… read more here.
