This paper deals the relationship between compressive strength and internal crack
formation (eg, crack width and volume) of cement-fiber-tailings matrix composites (CFTMC) …

In this paper, an experimental investigation was carried out to study strength, toughness and
microstructural properties of early age cemented tailings backfill (CTB) reinforced with three …

Cemented tailings backfill is an important development tendency of mine filling. Aiming at
the cemented rock-tailings backfill material, the experimental tests on the acoustic emission …

Layered filling is easy to lead to layered structure of cemented paste backfill (CPB). To
understand the mechanical behavior, failure modes, and damage evolution of layered …

The volume of the goaf in the hard rock mine vacancy method is much larger than the filling
capacity. The existence of layered interface and stacking angle during the filling in large-size …

Recycling gangue as the aggregate of cemented waste rock backfill (CWRB) to filling mining
is the most economical, environmental and friendly method, which solves the environmental …

Ground control is an integral element of mine design and worker safety. The use of concrete
pillars for underground mines is of paramount importance to maintaining the economic and …

The strength properties of cemented tailings backfill (CTB: an engineered mix of processing
tailings, hydraulic binder and mixing water) is strongly affected by its structural integrity …

The backfill does not exist independently in the stope, but is in contact with the surrounding
rocks to form a combination body to jointly bear pressure. In order to study the joint pressure …

Backfill mining method plays an important role in the treatment of tailings, and the failure law
of a cement paste backfill (CPB) and rock combination under pressure has essential guiding …
