Abstract (2. Language): 
The development and utilization of paste backfill technology has been evolving over the last two decades around the world. The mining industry was particularly interested in the technology for reducing costs associated with backfilling large open stopes. A significant environmental advantage, especially when tailings are acid generating, is that a large amount of tailings up to 60 percent can be disposed underground. This paper presents the behavior of cemented paste backfill with sulphide-rich, namely the chemical and mineralogical changes with time that affect the mechanical strength of the fill. This phenomena are illustrated with a case study that demonstrates the long-term mechanical properties of a cemented paste backfill sampled in situ.
Abstract (Original Language): 
Dünyada macun dolgu teknolojisinin gelişimi ve bundan faydalanımı son yirmi senedir büyük bir gelişme kaydetmiştir. Madencilik sektörü, yeraltında geniş üretimli açık alanların doldurulması ile ilgili maliyeti azaltıcı bu teknoloji ile özellikle ilgilenmektedir. En büyük avantajı, özellikle asit üreten atıklar da, büyük miktardaki tesis atıklarının (%60) yeraltında cevheri alınmış bölgelere yerleştirilmesidir. Bu çalışma, dolgunun mekanik mukavametine etki eden mineralojik ve kimyasal özelliklerinin sülfürce zengin çimentolu macun dolgu üzerinde davranışındaki gelişmeleri ortaya koymaktadır. Bu durum arazi de çimentolu macun dolgu örneklerinin uzun dönemli mekanik özelliklerinin incelenmesi ile ele alınmıştır.
