This paper focuses on the potential environmental benefits afforded by use of paste backfill technology when tailings are sulfide-bearing and provides a case study chosen from an underground mine in north-east Turkey in order to illustrate these benefits. Additionally, it includes discussions on different slump values with varying cement contents under 28-day uniaxial compressive strength tests for mine tailings and determines the rheological properties of mine tailings with respect to paste production.

Paste backfill was first developed by Preussag at the Bad Grund Mine. Filtered tailings were combined with 30 mm heavy media separation tailings to produce a paste backfill. These ingredients were combined and mixed on surface and pumped to the underground mine using two Putzmeister concrete pumps working in parallel. Dry cement was added to the paste mixture just prior to being placed into the stope. The resulting fill then formed the roof for the next cut using an undercut and fill mining method. The experimenta...

This study investigates the potential environmental impact of ground vibrations produced from blasting operations performed at AraklД±-TaЕџ\"on\"u limestone quarry where the school, mosque, historic place and village houses are situated. During the study, the parameters of scaled distance were recorded carefully, and the groundvibration components were measured at different locations by suitable monitors for 31 blast events. From the statistical analysis of the results, the general peak particle velocity equation ...
