Voids (referred to as “stopes”) are generally created during underground mining activities
and can lead to both local and regional geotechnical instabilities. To assist in managing the …

A primary challenge in the mining industry is how to extract mineral and metal resources in a
cost-effective and environmentally-friendly way. To help mitigate the environmental issues …

As a widespread application in underground metal mines, cementitious tailings backfill
(CTB) has a significant implication for recycling dangerous process tailings and enhancing …

Cemented backfilling has been widely used in underground mines worldwide. The stability
of cemented backfill must be sufficient to maintain the subsequent stope. Investigation into …

A series of mechanical and microstructural tests and monitoring experiments are performed
on different cemented paste backfill (CPB) specimens made with different types of tailings …

In the mining industry, backfill is used to stabilize mined-out underground excavations, and
backfill made from mine tailings has the added advantage of being sustainable and …

Microbes can induce the production of calcium carbonate deposits, which cement solid
wastes such as coal gangue to form backfill materials. Filling such backfill materials in …

The interaction between cemented paste backfill (CPB) and rock at their interface plays a
crucial role in the stability of underground backfill structures. Considering the interface …

To investigate on the strength and failure characteristics of cemented paste backfill-rock
(CPB-R) composite under uniaxial compression, specimen models of the CPB-R composite …

Cemented paste backfill (CPB) has been widely used as local and regional underground
support to reduce host rock wall closure in mined-out areas and also to reduce rockfall and …
