"A wide survey over four millennia is possible for quarrying tools and techniques because of their simplicity and long-lived traditions. The chief contribution of the Romans was their organisation of the stone trade by mass production, standardisation and long-distance transport. Indeed, in post-Roman Europe, especially in Britain, it was the excellence of …
Quarrying is used mainly in the production of construction and building materials, such as solid stone or crushed rock for aggregates, or for raw materials for processes such as cement manufacture. As a technique, quarrying is normally only used where raw materials of adequate quality and size cannot be obtained economically by other means.
— Quarrying, or removing gravel, sand, rock, and other minerals from the earth's surface, is a process to obtain materials for various purposes, primarily construction. Quarries have a long history and have been integral to erecting many ancient and modern artistic and engineering feats.
2.2 Limestone Quarrying Operations Extraction (more commonly referred to as quarrying) consists of removing blocks or pieces of stone from an identified and unearthed geologic deposit. Differences in the particular quarrying techniques used often stems from variations in the physical properties of the deposit itself—such as density,
— Quarrying techniques such as open-pit mining or underground mining are employed to access the marble deposits. Material Selection and Preparation: Once extracted, the marble blocks undergo sorting and grading based on factors such as color, quality, and structural integrity. High-quality blocks are selected for further processing.
