The limestone and sandstone quarries are contaminating the fresh groundwater aquifers of the region by increasing fluoride concentration and salinity in groundwater in this region. The surface and precipitated waters are directly exposed to these quarries. What is the process of quarrying?
Since a form of calcium carbonate, usually limestone, is the predominant raw material, most plants are situated near a limestone quarry or receive this material from a source via inexpensive transportation. Cement manufacturing begins with quarrying operations in which limestone in mines is quarried and brought to crusher for crushing.
Cement - Extraction, Processing, Manufacturing: Raw materials employed in the manufacture of cement are extracted by quarrying in the case of hard rocks such as limestones, slates, and some shales, with the aid of blasting when necessary. Some deposits are mined by underground methods. Softer rocks such as chalk and clay can …
In limestone quarries, ammonium nitrate–fuel oil (ANFO) or site mixed emulsion (SME) are generally used for rock fragmentation. Both these explosives cause substantial changes in the breakage mechanism of rockmass thereby affecting the fragmentation. This paper reports the effect of type of the explosive and blast hole …

The Southwell quarry is situated along the south eastern coast of Portland. This limestone quarry extends along the east of Portland Bill road, from Southwell all the way to the Portland Bill Observatory. Southwell quarry has reserves of over 1,264,000m³ and will be worked in the future. This equates to over 63 years of quarrying or mining.
A quarry is an area from which rocks such as marble, limestone, and granite are extracted for industrial use. Once depleted of their desired resources, quarries are frequently abandoned. The resulting gaping holes can fill with water and form dangerous quarry lakes while others are turned into unsightly landfills.
Construction minerals include the extraction of igneous rock (including granite), limestone, dolomite and chalk for construction use, sandstone, sand & gravel, slate, gypsum, clay & shale and fireclay. Brick clay is an essential raw material for the manufacture of bricks; limestone and chalk are the primary materials for the production of cement.
