The proposed method of classification of white marble ore resources and then estimation of reserves of commercial marble block volumes is demonstrated with the aid of a case study. …

Exploitation of natural stone The most important aspect in the exploitation of natural stone deposits is the need for extracting large and whole blocks and slabs of rocks with a uniform quality. This is done by wedging, careful blasting and primary sawing, or a combi-nation of these methods (Figs. 2 and 3). Sawing, especially by

The elephant fossils and stone tools were found in channel deposits towards the base of the sequence. The lowermost find was a complete elephant tusk within a sandy silt horizon, while the skull was discovered in overlying, loosely consolidated sandstone. ... trogontherii) exploitation dating to MIS 7-6, where various skeletal parts were found ...

In the second half of the 19th century, new methods for quarrying and processing natural stone were developed. In the Nordic countries Sweden, Norway, and Finland, this technological progress went hand in hand with a systematic geological mapping and large-scale exploitation of natural stone deposits. As a result, new constructions were developed, …

In this study, marble sludge from the exploitation and processing of Carrara marble (both in quarries and working plants) was analyzed to understand its characteristics and possibilities for reuse/recycling.

This study deals about the first exploitation project of an underground limestone quarry (known as Orosei Marble) of Sardinia. This project involves the development of the open cast quarry in

The process of natural stone exploration is often referred as a stepwise regional study aimed at iden tifying new deposits of natural stone (Heldal & Lund 1995, Shadmon 1996, Selonen 1998 ...

The coefficient of utilization of rock directly affects the profitability of the dimension stone deposit exploitation. Dimension stone is a highly valuable raw mineral material per unit of product. Past experience and literature show that for a certain amount of commercial dimension stone blocks, a significantly larger volume of raw rock mass ...

Marble extraction in the Carrara basins has occurred since the 1st millennium BC, with relevant exploitation periods during the Roman period and the Renaissance, when Michelangelo visited the ...

Haiti has considerable deposits of limestone and marble. The nation is home to the Cervicos limestone formation which dates back to the Paleogene period. ... Experts are also concerned that the nation's weak mining laws will allow exploitation of resources with little benefit to the nation's population. . Share. Benjamin Elisha Sawe January ...

Most of the marble deposits found in these areas form an elevated morphology, others have a flat, though well exposed, morphology. ... the basalt deposits are not considered to be of specific interest for more industrial-scaled building …

The use of natural stone has historical and environmental value that makes it strategically valuable for landscape conservation in Europe. Marble, among others, is widely spread on Earth, and it offers high-performance features in architectural applications. However, the complexity of these formations and the rock variability in different ore bodies require …

Most of the marble deposits found in these areas form an elevated morphology, others have a flat, though well exposed, morphology. ... the basalt deposits are not considered to be of specific interest for more industrial-scaled building stone exploitation, with the possible exception of columnar and vesicular basalt (Fig. 15). The former could ...

accompanied by systematic geological exploration and later by large-scale commercial exploitation of natural stone deposits. As a result, new constructions were developed that changed the practice of building. From this enthusiasm for natural stone, a new architectural language detached from historicism evolves.
