Pirit İçerikli Kayaçların Basma Dayanımı ve Bazı Fiziksel Parametreleri Arasındaki İlişkilerin Araştırılması

Bu çalışma, kayaçların fiziksel parametreleri (kohezyon (C), içsel sürtünme açısı (), birim hacim ağırlık (UW), ultrasonik P dalga hızı (UPV)) ve pirit içeriğinin (Py, %) kayaç basma dayanımı (UCS) ile arasındaki ilişkilerin incelenmesine odaklanmaktadır. Kayaçların parlak kesit analizleri, modern bir teknik olan trinoküler araştırma mikroskobuna entegre edilmiş Clemex görüntü analiz sistemi ve motorlu tabla ile gerçekleştirilmiştir. UCS ve Py arasında korelasyon analizi yapılmıştır. Korelasyon katsayısı (r=0.69) nispeten yüksek olmasına rağmen veri çiftleri arasında istatistik olarak anlamlı bir ilişki elde edilememiştir. Öte yandan, UCS ve bu çalışmada kullanılan pirit içeriği dahil diğer parametreler arasında çoklu regresyon analizi yapıldığında, istatistiksel açıdan önemli ve (p=0.003 and F=302.6) çok güçlü/yüksek determinasyon katsayısına (R 2=0.936) sahip tahmin modeli elde edilmiştir.

Investigation of the Relationships between Compressive Strength and Some Physical Parameters of Pyrite Containing Rocks

This study focuses on the investigation of the relationships between physical parameters (cohesion (C),internal friction angle (), unit weight (UW), ultrasonic P wave velocity (UPV)) and pyrite content (Py,%) with rock strength (UCS). Polished section analyses of rocks were performed via Clemex imageanalysis system and motorized table which are integrated into the trinocular research microscope thatis a modern technique. Correlation analysis was performed between UCS and Py. Statistically significantrelation wasn’t obtained between the data pairs even though coefficient of correlation is relatively high(r=0.69). However, a statistically significant relationship (with p=0.003 and F=302.6) was achieved withhigh coefficient of determination (R2=0.936) when multivariate regression analysis was carried outbetween UCS and other parameters including “Py” used in this study.
