Quarrying of Stone: Types, Methods & Tools
1.Wedging: This quarrying method is appropriate for costly, soft and stratified rocks such as sandstone, limestone, laterite, marble and slate. Holes about 10–15 cm deep, at a distance of about 10 cm are made perpendicular to the rock. Steel pins and wedges or plugs (conical wedges) and feathers are inserted into them, these plugs are Machine Quarrying of Stones. Machine quarrying is done by using channeling machines in the site.

Quarrying Of Stones Methods Of Quarrying Of Stones
Quarrying of stones is the art of extracting stones from the rock beds. The place from which the stones are obtained (by digging or blasting) is known as ‘Quarry’. Quarrying differs from mining in which various operations are carried out for exploring minerals, such as coal, quartzite, etc. from a mine under the ground. 2.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 Quarrying Process and Equipment Applications Epiroc

What Is Quarrying of Stones Methods of Quarrying
The building stones are obtained from rocks. These rocks have a distinct plane of division along which the stones can be easily split-up. This plane is known as a “natural bed of stone.”. In stone masonry, the general rule to be observed is the direction of the natural bed should be perpendicular to the direction of the pressure, such an Building stones should possess enough strength and durability. Stones have been considered as one of the popular building material from the olden days due to their availability in abundance from the natural rocks. 5.
