NİĞDE BÖLGESİ KALSİTLERİNİN KAZISINDA KOLLU GALERİ AÇMA MAKİNESİ KULLANILABİLİRLİĞİNİN ARAŞTIRILMASI

Öz

Niğde bölgesinde yer alan kalsit işletmeleri açık ocak madenciliği yöntemi ile işletilmekte ve bu işletmelerde kazı için delme patlatma yöntemleri kullanılmaktadır. Delme ve patlatma yönteminin masrafları toplam işletme masrafları içerisinde önemli bir parametredir. Bunun yanında özellikle verimsiz delme patlatma uygulamalarından sonra oluşan büyük bloklar da bu maliyeti artıracaktır. Mekanize kazı yöntemlerinin uygulandığı işletmelerde ise kazı işlemleri daha hızlı olmakta ve uygun kazıcının seçilmesi ile üretim maliyeti delme patlatma yöntemine kıyasla daha az olmaktadır. Yapılan bu çalışmada Niğde bölgesinde bulunan kalsit işletmelerinde kollu galeri açma makinesi (KGAM) kullanılabilirliği ve performansları araştırılmıştır. Bu kapsamda farklı kalsit işletmelerine ait hammadde sahalarından numuneler alınmış ve laboratuvar deneyleri ile fiziksel ve mekanik özellikleri belirlenmiştir. Farklı araştırmacılar tarafından geliştirilen performans tahmin modelleri kullanılarak kalsit kazısı için KGAM kazı performans tahmini yapılmıştır. Ayrıca, KGAM kullanımında önemli bir parametre olan kesici uç tüketimi de teorik yaklaşımlar kullanılarak hesaplanmıştır.

INVESTIGATION OF THE USABILITY OF ROADHEADERS IN EXCAVATION OF CALCITE IN NİĞDE REGION

Abstract

Open-pit mining method is used in many calcite mines located in Niğde region and drilling and blasting method is applied in these mines for excavation. The application costs of drilling and blasting are important parameters in total operating costs. In addition, especially large blocks obtained after inefficient drilling blasting applications will increase this cost. The excavations are faster in mines that using the mechanical excavators and by selecting the proper machine, the cost of production is less than the drilling and blasting method. In this study, the usability and performances of roadheaders were investigated in calcite mines in Niğde region. In this purpose, calcite samples were collected from the different calcite mines in Niğde region and firstly, their physical and mechanical properties were determined by laboratory tests. Then, for calcite excavation, the performance of KGAM was estimated with using performance prediction models developed by different researchers. In addition, cutter consumption rate, an important parameter in the use of KGAM, has been estimated using theoretical models.
