Numerical study on microscale and macroscale strength behaviors of hardening cemented paste backfill
(Elsevier, 2022)
Computer aided optimization of cement-based materials proportion can accurately quantify the accompanying microstructure evolution, material composition, and the mechanical properties changes. However, no relevant research ...
Numerical investigation of creeping rockmass interaction with hardening and shrinking cemented paste backfill
(Elsevier, 2022)
Revealing the interaction mechanism between the time-dependent deformation of rockmass and hardening backfill are important for successful mining design. Based on laboratory tests and numerical simulation, a framework has ...
Influence of types and contents of nano cellulose materials as reinforcement on stability performance of cementitious tailings backfill
(Elsevier, 2022)
This study explores the quality of cemented tailings backfill (CTB) reinforced with diverse nano cellulose materials (NCMs) such as micro-fibrillated cellulose (MFC), hydroxylated cellulose nanofiber (CNF), and cellulose ...
A joint experiment and discussion for strength characteristics of cemented paste backfill considering curing conditions
(MDPI, 2022)
As lots of underground mines have been exploited in the past decades, many stope instability and surface subsidence problems are appeared in the underground mines, while the cemented paste backfill (CPB) technology has ...
Curing stress effect on stability, microstructure, matric suction and electrical conductivity of cementitious tailings backfills
(Elsevier, 2022)
Cementitious tailings backfill (CTB) is a regularly used technique for most mines at home and aboard since it has a significant meaning for the recycling of total tailings and enhances the safety of underground mines. Thus, ...
Strength and microstructure evolution in cemented mine backfill with low and high pH pyritic tailings: Effect of mineral admixtures
(Elsevier, 2022)
To properly dispose mining-induced tailings, diverse techniques including cemented paste fill (CPB) have been already employed. Indeed, tailings are manufactured by using different admixtures which are poisonous to the ...
Recycling dam tailings as cemented mine backfill: Mechanical and geotechnical properties
(Hindawi, 2022)
As a result of developing technology and scientific studies, employing dam tailings as critical raw material and vital economic reserve has become widespread recently. Employing dam tailings as a main ingredient of CPB ...
