Abstract

   Drillability is defined as penetration
rate of a drill bit in a rock or formation. An economical completion of
drilling operations in a short time in all stages of mining, in engineering
works such as dam, road construction, tunnels and sewage, blasting holes are
very important in terms of operating costs. Economical and rapid drilling,
mineralogy of the rock, mechanical properties and type of drilling used are
directly related. The rock properties are used as a criterion of drillability
as they are applicable as standard throughout the world. This paper presents
the results of an experimental study carried out to estimate the rate of penetration
in CaCO₃ based rocks by various rock and aggregate tests. The aim of the study is to develop rate of penetration
models with the regression analyses by the combination of rock parameters
affecting drillability and the data obtained from laboratory core drilling
tests. With
simple and multiple regression studies, equations a high correlation
coefficient are obtained in predicting the drilling rate.

CaCO3 İÇEREN KAYAÇLARIN SONDAJ İLERLEME HIZININ KAYAÇ ÖZELLİKLERİNDEN TAHMİN EDİLMESİ

Abstract

   Delinebilirlik,
matkap ucunun formasyon veya kaya içerisindeki ilerleme hızı olarak tarif
edilir. Madenciliğin tüm aşamalarında, baraj, yol yapımı, tünel ve kanalizasyon
gibi mühendislik çalışmalarında patlatma deliklerinin olabildiğince ekonomik ve
kısa zamanda delinebilmesi işletme maliyeti açısından oldukça önemlidir.
Ekonomik ve hızlı sondaj, kayacın mineralojisi, mekanik özellikleri ve
kullanılan matkap tipi ile doğrudan ilişkilidir. Kayaç özellikleri, dünyanın
her yerinde standart olarak uygulanabilir olduklarından delinebilirlik ölçütü
olarak kullanılmaktadır. Bu makale, CaCO₃
esaslı kayaçlarda sondaj ilerleme hızının çeşitli kaya ve agrega testleri ile
tahmin edilmesi için gerçekleştirilmiş deneysel bir çalışmanın sonuçlarını
içermektedir. Çalışmanın amacı,
delinebilirliğe etki eden kayaç parametreleri ile laboratuvar karotlu sondaj
çalışmalarından elde edilen veriler arasında regresyon analizi ile delme hızı
tahmin modellerinin geliştirilmesidir. Yapılan
basit ve çoklu regresyon modelleri ile sondaj ilerleme hızının tahmininde
yüksek korelasyon değerlerine sahip eşitlikler elde edilmiştir.
