Abstract

The rock-cutting or drilling tool interaction will not be the same on saw-cut and rough rock surfaces. Therefore, the effects of the textural properties of the rocks, which vary depending on their mineralogical and petrographical characteristics, on the wear of the cutting toll will also vary. In this study, the effect of the surface properties of rocks on the relationship between their textural and abrasivity properties was investigated. Cerchar abrasivity index (CAI) values of rocks were determined on saw-cut and rough surfaces using two different Cerchar test apparatus (classic and West) on 11 different rock samples. Textural coefficient (TC) and ratio of total mineral area to cross-sectional area values (AW) were determined from thin-section images to define the textural properties of rocks. The relationships between CAI values, determined with both test devices, and TC and AW were statistically analyzed for rough and saw-cut surfaces. It was revealed that the effect of the textural properties of rocks on their abrasivity is higher on rough surfaces.

Kayaçların dokusal özellikleri ile aşındırıcılıkları arasındaki ilişkiye yüzey özelliği etkisinin farklı deney aletleri ile araştırılması

Abstract

Düz ve pürüzlü kayaç yüzeylerinde kesici ve delici uç ile kaya etkileşimi aynı olmayacaktır. Dolayısıyla, bu yüzeylerde kayaçların mineralojisine bağlı olarak değişen dokusal özelliklerinin kesici uç aşınmasına etkileri de değişiklik gösterecektir. Bu çalışmada kayaçların dokusal özellikleri ile aşındırıcılıkları arasındaki ilişkiye numune yüzey özelliğinin etkisi araştırılmıştır. 11 farklı kayaç numunesi üzerinde iki farklı Cerchar deney aleti (klasik ve West) kullanılarak kayaçların Cerchar aşındırıcılık indeks değerleri (CAI) testere ile kesilmiş ve pürüzlü yüzeylerde belirlenmiştir. Kayaçların dokusal özelliklerinin belirlenmesi amacıyla da ince kesit görüntüleri üzerinden doku katsayısı ve mineral toplam alanının kesit alanına oranı (AW) değerleri belirlenmiştir. Elde edilen bu değerler ile her iki deney aleti kullanılarak belirlenen CAI değerleri arasındaki ilişkiler pürüzlü ve kesilmiş (düz) yüzeyler için istatistiksel olarak analiz edilmiştir. Kayaçların dokusal özelliklerinin aşındırıcılıkları üzerindeki etkisinin pürüzlü yüzeylerde daha fazla olduğu belirlenmiştir.
