The way an individual quarry is operated can vary enormously. The physical characteristics of the rock mass (how homogeneous it is, and whether there are defined lines of weakness such as regular fracturing or lamination), the size of both the resource and the market for its products, and the financial resources of the operator, all play a role in deciding the …

Quarrying of Stones. Definition: Stones occur in the form of natural rock masses or layers on the surface. The process of extraction of suitable stones from their natural rock beds or layers is commonly called Quarrying of Stones.. It differs from the mining of ores of metals in that whereas quarrying is an operation carried out entirely on the surface, mining involves digging …

3.1 Industrial requirements for quarrying and processing an entire granite block into tiles. The energy requirements for quarrying a granite block and processing it into finished tiles are displayed in Table 1.The water and material balances of the granite production chain, which is shown graphically in Fig. 2, were performed using the software Sankey®.
'Quarrying processes' published in 'Beaches and Coastal Geology' This process refers to the removal of rocks from a cliff or wave-cut platform from their in situ position by wave action. Continued wave attack on a cliff or platform edge exerts tremendous hydraulic pressure and erosive force along lines of weakness, often bedding and joint lines.
The chain of production is the various stages through which the production of goods passes to reach the consumer. The three kinds of production are linked together in the production process. The chain of production begins with primary production and is not complete until the goods reach the consumer, as can be seen from Fig. 1.3.
