Applicability of Texture Coefficient Concept for the Prediction of Pick Performance in Rock Cutting

Year 2003, Volume: 42 Issue: 2, 27 - 43, 01.06.2003

Abstract

Prediction of the performance of the rock cutting tools (picks) is very important in selecting mechanical excavators. In literature, studies related to the prediction of pick cutting performance referring to textural and compositional rock properties are very few. This paper is aimed to describe the studies on applicability of texture coefficient concept that was previously developed during rock drillability studies, for the estimation of specific cutting energy in rock cutting. In these studies, comprehensive mineralogical and pétrographie analyses, rock mechanics and rock cutting experiments were carried out on some selected sandstone samples. A new method concerning the details of mineral grains included in rock pieces in thin sections were employed through the calculations of individual texture coefficient values. Results of statistical analysis carried out on data obtained from these experiments revealed that, there were statistically strong relationships between the texture coefficient, packing density and specific cutting energy. The significance of the texture coefficient concept in rock cutting was put forward for the first time in literature within this study

KAYAÇ KESMEDE KESKİ PERFORMASININ TAHMİNİ İÇİN DOKU KATSAYISI YAKLAŞIMININ KULLANILABİLİRLİĞİ

Year 2003, Volume: 42 Issue: 2, 27 - 43, 01.06.2003

Abstract

Mekanik kazıcıların seçiminde, keskinin kazı sırasında göstereceği performansın tahmini çok önemlidir. Keski performansının, dokusal ve bileşimsel kayaç özelliklerinden hareketle tahmin edilebilirliği ile ilgili olarak literatürde az sayıda çalışma bulunmaktadır. Bu yazıda, kayaç delme çalışmalarında geliştirilen doku katsayısı yaklaşımının, kayaç kesmede özgül kesme enerjisinin belirlenmesinde kullanılabilirliği ile ilgili olarak yapılan çalışmalar anlatılmaktadır. Bu çalışmalarda, seçilen kumtaşı örnekleri üzerinde kapsamlı mineralojik-petrografik analizler, kaya ve kazı mekaniği deneyleri yapılmıştır. Doku katsayısı hesabında kayaç parçaları içindeki mineral tanelerini dikkate alan yeni bir yöntem kullanılmıştır. Elde edilen verilerin istatistiksel analiz sonuçları, doku katsayısı ve paketlenme yoğunluğunun, özgül kesme enerjisi ile istatistiksel açıdan kabul edilebilir bir ilişki içinde olduklarını göstermiştir. Bu çalışmada, doku katsayısı yaklaşımının kayaç kesmedeki önemi literatürde ilk kez olmak üzere ortaya konmuştur
