In mining: Quarrying .and monuments is known as dimension stone. The characteristics required of good dimension stone are uniformity of texture and colour, freedom from flaws, suitability for polishing and carving, and resistance to weathering. This section describes the quarrying of dimension stone.
Prospecting for, and mining and production of dimension stone are more sophisticated and require more care than the same processes or the methods used for natural stone aggregate or sand and gravel. The dimensionstone market for all rock types is .
stripping by conventional surface methods. Quarrying of dimension stone and highwall mining are specialized and less frequently used methods, and will not be looked at in detail in this report. Aqueous extraction in most cases involves the use of water or a liquid solvent to flush

Dimension stone in use can last many generations, even centuries, so the dimension stone manufacturers have not needed a product recycling program. However, there are practical qualifications to and constraints on that sustainability. The dimension stone color and pattern can be changed by weathering when it is very near the surface.
Dimension stone can be defined as natural rock material quarried for the purpose of obtaining blocks or slabs that meet specifications as to size (width, length, and thickness) and shape. Color, grain texture and pattern, and surface finish of the stone are normal requirements.

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, fracturing/bedding planes, and depth—financial considerations, and the site owner''s preference.
Nov 30, 2010· The profitable production of dimension stone mainly depends on the extractable block size. The regularity and volume of the blocks are of critical importance, and are controlled by the threedimensional pattern of the discontinuity system. Therefore, optimization of block size has to be the aim when quarrying for natural stone.

Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef or placer deposits form a mineralized package that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.
Mining Techniques is divided into two types: surface mining and underground targets are divided into two categories of materials: placer deposits and lode deposits. If a mineral is stable chemically and is resistant physically, it can be eroded from its primary hardrock occurrence and transported to river channels, deltas or other sedimentary environments where it can be ...
Quarry, place where dimension stone or aggregate (sand, gravel, crushed rock) is mined. The products of dimension stone quarries are prismatic blocks of rock such as marble, granite, limestone, sandstone, and slate. After cutting and polishing, these materials are used in the primary construction

Relation to Mining. IMAR 7 th Edition. Dimension Stone is produced from quarrying. Quarry operations typically involve isolating a mass of stone by cutting it free from the parent mass on all sides but one. The isolated mass is then lifted or separated from the parent mass by breaking it free or by undercutting it with a wire or chain saw.
