Abstract

Production efficiency in marble quarries can only be accurately evaluated by understanding the geological and structural factors that control production, rather than merely determining the production quantities. In this study, production processes at the Mabella Marble Quarry, located in the Muğla Yılanlı Region, were quantitatively determined using unmanned aerial vehicle (UAV)-based three-dimensional modeling, and the resulting data were evaluated alongside geological discontinuity characteristics. Within the scope of the study, aerial photographs obtained using high-precision ground control points (GCPs) were processed through photogrammetric methods to generate digital surface models and perform volume calculations. Based on the obtained 3D models, annual production and overburden volumes were quantified, while field-derived data were utilized to analyze discontinuity orientation, spacing, and blockiness properties. Findings indicate that rock mass discontinuity properties—rather than mere output quantities—are the fundamental determinants of block efficiency. In particular, the density and orientation of these discontinuities have been identified as key factors that restrict block dimensions and consequently elevate waste ratios. This highlights a critical inefficiency in the production process, where a large proportion of the rock mass is relegated to waste piles instead of yielding marketable economic value. The results demonstrate that UAV-based 3D modeling transcends simple volumetric estimation, serving as a robust analytical instrument for deciphering the geological constraints that govern extraction productivity. This approach contributes to the improvement of production planning in marble quarries and the development of strategies aimed at reducing waste quantities.

Özet

Mermer ocaklarında üretim verimliliği, yalnızca üretim miktarlarının belirlenmesi ile değil, bu üretimi kontrol eden jeolojik ve yapısal faktörlerin anlaşılması ile doğru şekilde değerlendirilebilmektedir. Bu çalışmada, Muğla Yılanlı Bölgesi’nde yer alan Mabella Mermer Ocağı’nda üretim süreçleri, insansız hava aracı (İHA) tabanlı üç boyutlu modelleme ile nicel olarak ortaya konulmuş ve elde edilen veriler jeolojik süreksizlik özellikleri ile birlikte değerlendirilmiştir. Çalışma kapsamında, yüksek hassasiyetli yer kontrol noktaları kullanılarak elde edilen hava fotoğrafları fotogrametrik yöntemlerle işlenmiş, sayısal yüzey modeli ve hacim hesaplamaları gerçekleştirilmiştir. Elde edilen üç boyutlu modeller üzerinden yıllık üretim ve pasa hacimleri belirlenmiş; bununla birlikte saha verileri kullanılarak süreksizlik yönelimi, sıklığı ve bloklanma özellikleri analiz edilmiştir. Sonuçlar, üretim miktarlarının nicel olarak belirlenmesinin ötesinde, blok verimliliğini kontrol eden temel faktörün kaya kütlesi süreksizlik özellikleri olduğunu göstermektedir. Özellikle süreksizlik yoğunluğu ve yöneliminin, blok boyutlarını sınırlandırarak pasa oranının artmasına neden olduğu belirlenmiştir. Bu durum, üretim sırasında yüksek miktarda malzemenin ekonomik değere dönüştürülemeden atık olarak ayrıldığını ortaya koymaktadır. Elde edilen bulgular, İHA tabanlı üç boyutlu modelleme yöntemlerinin yalnızca hacim hesaplamalarında değil, aynı zamanda üretim verimliliğinin jeolojik kontrol mekanizmalarının anlaşılmasında da etkin bir araç olduğunu göstermektedir. Bu yaklaşım, mermer ocaklarında üretim planlamasının iyileştirilmesi ve pasa miktarının azaltılmasına yönelik stratejilerin geliştirilmesine katkı sunmaktadır.
