The quarrying of marble is different from the mining of other minerals. In marble quarrying large size of blocks are excavated. In India stones are excavated mainly by open case mines but in Italy and some other countries deeper deposits are excavated by underground mines. Earlier extraction of marble was done manually by using jack …

With the increasing requirements for the exploitation of underground resources, the subject of the physical and mechanical properties of rocks under high temperature and pressure needs to be studied urgently. In order to analyze the mechanical and energy characteristics of rocks under different thermal damages and confining …
Based on the numerical simulation results, the evolution law for the strength parameters of marble with the degree of damage is described. According to the proportional relationship between the peak stress and crack initiation stress, a new method for predicting the initiation stress is proposed, whose effectiveness is verified.

The marble industry was flourishing well before demonetization and GST were introduced; but now everything has gone awry. Declining sales, long hours of work and drowning are swallowing the glow of the marble are the new norms. A report of mining department observes that employment level in this industry has come down from 30% to …

It has come about through careless and unplanned marble mining in the river's catchment and the blocking of rivulets through the dumping of marble overburden and slurry. The river has been reduced to a narrow, seasonal stream that comes alive only during the monsoon.
T he story of Italian marble is the story of difficult motion: violent, geological, haunted by failure and ruin and lost fortunes, marred by severed fingers, crushed dreams, crushed men.
Excavating marble can be ecologically harmful and energy intensive. Marble is mined at quarries across Italy, Greece, and the United States, among others. Its …
Marble is a metamorphic rock present in the earth crust in abundance. Different types of marble are found in Buner in different places. In this study Bampokha region mines were surveyedto...
The rate of mining marble is controlled by its demand, extraction costs, mining locations, and market value, Elrick says. This means that as the easy and cheap to extract marble resources...
Mining activities, on the other hand, harm the environment. The main impact given by mining is on environmental damage and the reduction of non-renewable natural resources [18]. This impact is obtained from mining operations that do not pay attention to the sustainability of the resource itself. Strategic Value of Marble Mine Management for ...
History. Known as the "Marble Capital of the World", Carrara, a small town in central and northern Italy, has the world's most diverse and best-quality white marble. It was a high-end architectural and sculpture material that was popular in Europe during the Roman era and is almost one of the five largest stone mines in the world The most ...
Once built, the Amoco building was the world's tallest marble-clad building, utilising 43,000 slabs of Italian Carrara marble. …
addition, the extraction of the marble blocks from the mountain sides does involve a noticeable quantity of explosives, particularly in sites where traditional working methods are utilized. Another important feature of the marble mining is represented by the high level of waste materials released during the quarrying process.
