Tora, Egypt
Tura ( '  , , ) was the primary quarry for limestone in ancient Egypt. The site, which was known by the ancient Egyptians as ''Troyu'' or ''Royu'', is located about halfway between modern-day Cairo and Helwan. Its ancient Egyptian name was misinterpreted by the ancient Greek geographer Strabo, who thought it meant it was inhabited by Trojans, thus the Hellenistic city was named Troia. The site is located by the modern town of Tora in the Cairo Governorate. The limestone from the quarry is thought to be part of the Mokattam Formation, which was deposited during the late Lutetian stage of the Eocene epoch, about 42 million years. Some fossil fish species have been described from the quarry. Ancient mining town The limestone from Tura was the finest and whitest of all the Egyptian quarries, so it was used for facing stones for the richest tombs, as well as for the floors and ceilings of mastabas, which were otherwise made of mudbrick. It was used during the Old Kingdom and w ...

Limestone
Limestone is a type of carbonate rock, carbonate sedimentary rock which is the main source of the material Lime (material), lime. It is composed mostly of the minerals calcite and aragonite, which are different Polymorphism (materials science), crystal forms of calcium carbonate . Limestone forms when these minerals Precipitation (chemistry), precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly Dolomite (rock), dolomite, a closely related rock, which contains a high percentage of the mineral Dolomite (mine ...

He introduced major innovations in the design and construction of pyramids, and at least three of his pyramids survive to this day. Estimates of his reign vary, with for instance ''The Oxford History of Ancient Egypt'' suggesting a reign from around 2613 to 2589 BC, a reign of 24 years, while Rolf Krauss suggests a 30-year reign, and Rainer Stadelmann a 48-year reign. Sneferu's name His name means "He has perfected me", from ''Ḥr-nb-mꜣꜥt-snfr-wj'' "Horus, Lord of Maat, has perfected me", and is sometimes read Snefru or Snofru.

Open-pit Mining
Open-pit mining, also known as open-cast or open-cut mining and in larger contexts mega-mining, is a surface mining technique that extracts rock (geology), rock or minerals from the earth. Open-pit mines are used when deposits of commercially useful ore or rocks are found near the surface where the overburden is relatively thin. In contrast, deeper mineral deposits can be reached using underground mining. Open-pit mining is considered one of the most dangerous industrial sector, sectors in the industrial world. It causes significant effects to miners' health, as well as damage to the ecological land and water. Open-pit mining causes changes to vegetation, soil, and bedrock, which ultimately contributes to changes in surface hydrology, groundwater levels, and flow paths. Additionally, open-pit produces harmful pollutants depending on the type of mineral being mined, and the type of mining process being used. Extraction Miners typically drill a series of test holes to locate ...
