Preliminary investigation on impression creep behaviour of different zones (base metal, weld metal and Heat Affected Zone) of similar and dissimilar Cr-Mo steel welded joints in as welded and PWHT conditions has been attempted. It has been possible to evaluate the steady state creep rate of different zones and PWHT has shown a detrimental effect on the impression creep resistance of all weldments.

Solid-to-water proportion decides the effectiveness of paste backfill in terms of transportation characteristics during mine backfilling. This article highlights various laboratory tests conducted to determine the optimum solid-to-water ratio. Also, numerical simulation was carried out using computational fluid dynamics technique (ANSYS FLUENT) to understand the slump lifting process and variation in volume of the paste with time. The optimum slump and spread for lead–zinc mill tailings paste were in the range 190– 200 mm and 330–340 mm respectively. The optimum water content in the paste fill for this study was found to be 23 wt%. Results show that the solid percentage is inversely related with slump and spread. Also, an optimum slump lifting speed needs to be maintained for accurate values of slump and spread.Keywords
