Sharp picks become blunt due to wear in
time and require replacement. Although it is known that the pick blunting
affects adversely the rock cuttability, no study exists to show the
relationships between the degree of pick wear and the cutting specific energy
obtained by standard cutting tests. In this study, standard cutting tests were
carried out on different rock types, with picks having varying degrees of
blunting and the relationships between the uniaxial compressive strength
parameter were established.

Anahtar Kelimeler

Wear flat, uniaxial compressive strength, cutting picks

KESİCİ UÇLAR VE KESME PERFORMANSININ TEK EKSENLİ BASMA DAYANIMINA ETKİSİ

Öz

Keskin uçlar aşınmaya bağlı olarak
zamanla körleşmekte ve değiştirilmeleri gerekmektedir. Kesici uçlardaki
körleşmenin kayaçların kesilebilirliğini olumsuz etkilediği bilinmekle
birlikte, körleşme derecesi ile standart kesme deneyleri sonucu elde edilen kesme
özgül enerjisi arasındaki ilişki üzerine bir çalışma henüz bulunmamaktadır. Bu
çalışmada, değişik körleşme derecelerindeki kesici uçlar kullanılarak değişik
kayaçlar üzerinde standart kesme deneyleri yapılmış ve tek eksenli basma
dayanımı parametresi ile aralarındaki ilişkiler saptanmıştır.

Anahtar Kelimeler

Aşınma yüzeyi genişliği, tek eksenli basma dayanımı, kesici uçlar
