Goaf instability in an open pit iron mine triggered by dynamics disturbance: a large-scale similar simulation
(Taylor & Francis Ltd., 2023)
The stability of concealed goafs in open-pit mines under the influence of blasting disturbances is directly related to successful mining production. Based on large-scale similar simulations, this study steadily analyses ...
Identifcation of goaf instability under blasting disturbance using microseismic monitoring technology
(Springer, 2023)
Micro-seismic (MS) technique can be used to appreciate rock failure process and severity of damage by quantifying micro-earthquakes in terms of time, location, grade, and energy release. Based on 3D laser detection and ...
Mechanical, energy evolution, damage and microstructural behavior of cemented tailings-rock fill considering rock content and size effects
(Elsevier, 2024)
Cemented tailings-rock fill (CTRF) is crucial for engineering intention and durability of re-filled stopes in deep underground mines. The current work examined the effects of fragment contents and sizes on the mechanical, ...
Enhancing flexural property and mesoscopic mechanism of cementitious tailings backfill fabricated with 3D-printed polymers
(Elsevier, 2024)
Backfill mining, one of the most common methods for removing hazardous tailings, is performed on cementitious tailings backfill (CTB), which can be employed to fully discard risky tailings while diminishing the ecological ...
