KAYAÇ DOKULARINDAKİ MİNERALLERİN BAZI ŞEKİL ÖZELLİKLERİ İLE KAYAÇ KIRILABİLİRLİĞİ ARASINDAKİ İLİŞKİNİN İNCELENMESİ
Öz
Kayaçların
kırılganlık özellikleri endüstriyel boyutta oldukça önemli bir parametre olup
farklı şekillerde belirlenebilmektedir. Kayaç içerisindeki mineral
özelliklerinin kayaçların kırılganlıklarına etkisi vardır ve bu çalışmada bu
iki kavram arasındaki ilişki araştırılmıştır. Bu doğrultuda beş farklı kayaç
numunesinin kırılganlık özellikleri; belirli bir boyuttaki numunelerin çeneli
kırıcıda kırılıp, kırılan bu malzemelerden belirli elek açıklığının altında
kalan miktarının hesaplanmasıyla belirlenmiştir. Mineral özellikleri
belirlenirken doku katsayısı yaklaşımı kullanılmış ve bu yaklaşımda
minerallerin şekilsel özellikleri dikkatte alınmıştır. Elde edilen veriler
istatistiksel olarak değerlendirilmiş ve kayaçların kırılabilirlik indeksi (CI)
ve tane boyutu (d50, d80) ile doku katsayısı (TC)
değerleri arasında güçlü bir ilişki elde edilmiştir. Ayrıca, kayaçların
sertliklerinin belirlenmesi amacı ile Schmidt sertlik değerleri (SH)
belirlenmiş ve doku katsayısı değerleri ile arasındaki ilişki araştırılmış ve
belirli bir ilişki olduğu ortaya çıkarılmıştır.

INVESTIGATION OF THE RELATIONSHIP BETWEEN SOME SHAPE PROPERTIES OF MINERALS WITHIN ROCK TEXTURES AND CRUSHABILITY OF ROCKS
Öz
The crushability properties of rocks are very important parameters in
industrial scale and they can be determined by different methods. The mineral
properties in the rock have effects on rock crushability and in this study; the
relationship between mineral properties and rock crushability was investigated.
According to this, the crushability properties of five different rock samples
were determined by calculating the amount of material passing a given mesh
opening, after the rock samples of a certain size were broken by using a jaw
crusher. When the mineral properties were determined, the texture coefficient
approach was used and the shape characteristics of the minerals were also taken
into consideration. The obtained data from laboratory tests and image analysis
of rocks were evaluated statistically and strong correlations between the
crushability index (CI) of the rocks, particle size (d50,
d80) and the values of the texture coefficients (TC) were
found. In addition, Schmidt hardness (SH) tests were performed for determining
the hardness values of the rocks and correlated with the texture coefficients
and obtained a good relationship.
