Abstract

LABORATUVAR ÇALIŞMALARINA BAĞLI OLARAK KAYAÇLARIN P-DALGA HIZI VE SCHMIDT ÇEKİCİ SERTLİĞİ DEĞERLERİ KULLANILARAK ÖZGÜL ENERJİNİN TAHMİNİ

Abstract

Spesifik enerji değeri mekanik kayaç kazısında kayaçların kesilebilirlik özelliklerini belirlemek için

yaygın olarak kullanılmaktadır. Mekanik kayaç kazısı işlemlerinde mühendisler, spesifik enerji

değerine bağlı olarak makine performansını tahmin etmek için kolay uygulanabilir, daha ekonomik

ve basit örnek hazırlama yöntemlerinin kullanıldığı yöntemlere ihtiyaç duyarlar. Bu çalışmada,

spesifik enerjinin tahmini için pratik, basit ve ucuz bir test olduğu düşünülen kayaçların P-dalga

hızı (Vp) ve Schmidt çekici sertlik (RL) değerleri değişken olarak önerilmiştir. Bu amaçla 24 farklı

kaya numunesi üzerinde kaya kesme ile Vp ve R L testleri yapılmıştır. Elde edilen Vp ve R L ile

spesifik enerji değerleri SPSS 15.0 programı kullanılarak basit ve çoklu regresyon analizi ile

değerlendirilmiştir. Bu değerlendirme sonucunda kayaçların spesifik enerji, Vp ve R L değerleri

arasında güçlü bir ilişki olduğu belirlenmiştir. İstatistiksel analizlere göre, laboratuar çalışmalarına

bağlı olarak kayaların Vp ve RL değerleri kullanılarak spesifik enerji değerleri güvenilir bir şekilde

tahmin edilebilir.
