On the effect of green nonstructural materials on scour reduction downstream of grid dissipators
(IWA Publishing, 2023)In this study, a nonstructural and eco-friendly solution has been used to reduce scouring downstream of screens. Upstream of the screen are stilling basins protected against scouring, but downstream locations are subjected ... -
Admixture effects on the rheological/mechanical behavior and micro-structure evolution of alkali-activated slag backfills
(MDPI, 2023)Recently, alkali-activated slag (AAS) has attracted extensive attention in cemented paste backfill (CPB) due to its low cost/CO2 emissions and high strength benefits. However, a comprehensive analysis of the mechanical/rheological ... -
A study on the contact problem of a layer consisting of functionally graded material (FGM) in the presence of body force
(Mathematical Science Publishing, 2023)One of the most important components of the early design process for layered systems is gaining a knowledge of the behavior of materials under varied contact situations. Functionally graded materials (FGMs) have grown in ... -
Effect of content and length of polypropylene fibers on strength and microstructure of cementitious tailings-waste rock fill
(MDPI, 2023)The mechanical strength properties of cemented tailings backfill are very important for the safe and environmentally friendly mining of mineral resources. To check the impact of polypropylene fiber on strength and ... -
Effect of layer thickness on the flexural property and microstructure of 3D-printed rhomboid polymer-reinforced cemented tailing composites
(Springer, 2023)For mines with poor ore bodies and surrounding rocks, the general mining method does not allow the ore to be extracted from underground safely and efficiently. For these mines, the downward layered filling mining technique ... -
Progress and prospects of mining with backfill in metal mines in China
