Analysis of strength and microstructural characteristics of mine backfills containing fly ash and desulfurized gypsum
(MDPI, 2021)The utilization of solid wastes (SWs) as a potential resource for backfilling is not only conducive to environmental protection but also reduces the surface storage of waste. Two types of SWs, including fly ash (FA) and ... -
Characterization of macro mechanical properties and microstructures of cement-based composites prepared from fly ash, gypsum and steel slag
(MDPI, 2022)Using solid wastes (SWs) as backfilling material to fill underground mined-out areas (UMOAs) solved the environmental problems caused by SWs and reduced the backfilling cost. In this study, fly ash (FA), gypsum and steel ... -
Effect of 3D printed skeleton shapes on strength behavior, stress evolution and microstructural response of cement-based tailings backfills
(Elsevier, 2024)The inherent brittle behavior of cement-based tail backfill (CTB) poses some challenges that can significantly impact the safety and effectiveness of underground mining operations. Due to its propensity for abrupt and ... -
Influence of industrial solid waste as filling material on mechanical and microstructural characteristics of cementitious backfills
(Elsevier, 2021)Use of industrial solid wastes (e.g., fly ash, desulfurization gypsum, steel slag) as mine fill material not only solves the environmental risks dictated by the sustainable management of these wastes, but also reduces the ... -
Investigation on the flexural strength, failure pattern and microstructural characteristics of combined fibers reinforced cemented tailings backfill
(Elsevier, 2021)The brittleness of the cemented tailings backfill (CTB) can easily cause collapse, which seriously threatens the safety of underground mining workers and equipment. Studies have shown that fibers can improve the ductility ...
