The dimension stone industry is not widely known or appreciated within the mainstream mining industry. This is in spite of the fact that the industry has grown at an average of
Dimension Stone: Exploration and Exploitation in parts of Lokoja, NorthCentral Nigeria April Journal of Applied Sciences and Environmental Management
The study area Lokoja is the home to the confluence between Rivers Niger and Benue. Dimension stone is cut or quarried stone in accordance with specific
Iran has very high potential for production and export of dimension stone (rock quarried to size and shape specifications); Nevertheless, in spite of growing mine
The main purpose of all undertaken explorations was to evaluate the location’s acceptability for future exploitation of the architectural structural stone, in the manner of extraction of dimension stones .The research site is located in the Republic of Croatia, on the island of Brač, the largest island of central Dalmatia.
The algorithm used in this study can be applied as a powerful tool in the planning of a quarry and the future exploitation of dimension stone. Application of the described approach is demonstrated on practical examples of quarrying natural stones, namely, sandstone, granite, rhyolite, etc. Block quarrying can be optimized by using the new 3D
In addition, the results are applicable in the dimension stone exploration and exploitation phase in order to assess and reduce energy consumption by optimizing the operating parameters of the chain cutter and/or the hydraulic rotary drill. Keywords: mechanical rock fragmentation;
The process of dimension stone exploration as defined in this paper is a systematic and stepwise (Table 2) regional study, in which ‘new’ dimension stone deposits are identified in a large target area. The individual stages in this procedure can also be applied, for example, to site investigations or quarry development.
The exploitation of dimension stones, especially marble, has always been important for Greek economy. In the dimension stone market, granite and schist are also included. However, marble is by far the most important product of the dimension stone market of Greece. An attempt to highlight the trends of the last decade in the market of
Exploitation of these rocks could be as rough unprocessed dimension stone or better polished natural stones for a variety of uses. Nigeria can eliminate export tax rebate on dimension stone for a longterm significant production, exportation and usage. Small and mediumscale enterprises with appropriate technical knowhow can be
Dimension Stone: Exploration and Exploitation.. 427 EGESI, N; NWOSU, JI The procedure for dimension mining is quite different from aggregates quarrying. For aggregates the drilling of holes for blasting could be staggered, square, or rectangular, while lines which are square or rectangular are for dimension stone production. In the
This research aims to show the capability of unmanned aerial vehicles (UAVs) for aerial fracturing survey, determining the block size, and estimating the reserve of dimension stone deposits. The Majestic Rose marble quarry in Kerman province, Iran, was selected as the case study. The quarry presents large outcrops and rugged topography.
Iran has very high potential for production and export of dimension stone (rock quarried to size and shape specifications); Nevertheless, in spite of growing mine production during the past decade, in many instances this potential has been overlooked. Iran’s share in global market’s stones is small. Construction, decorative, and facing
Unit dimension stone blocks exploitation price for surface exploitation increased 3,5 times, and for underground exploitation 1,9 times from block 1 to 12. The profit of underground exploitation from block 1 to 12 is growing with a slower growth in profit in the last exploitation optimization blocks and the period of stagnation is noticed.
The dimension stone sector is strongly developing: China, India, Turkey and Iran lead the world quarry production while China and Italy lead the processed stone export. The world quarry net product is expected to reach one hundredtwenty million tons in 2025 ( Montani, ), which, in any case, represents a prudent mediumterm forecast.
In addition, the results are applicable in the dimension stone exploration and exploitation phase in order to assess and reduce energy consumption by optimizing the operating parameters of the chain cutter and/or the hydraulic rotary drill. Keywords: mechanical rock fragmentation;
This is beneficial as joints can be used for extraction of blocks and prevent unnecessary fragmentation of natural stone blocks. The horizontal joints tend to be neglected, since they are not observed so easily (Palmstrom, 2001), but are very important in dimension stone exploitation despite the increasing spacing at depth (Sousa et al., ).

Exploitation by diamond wire cutting method. Dimension stone is a natural stone selected or fabricated (i.e., cut, trimmed or others) to specific shape and size like blocks and slabs (Thrush et al., 1968). Dimension stones, which are widely used in building industry, can be divided into two major sections of calcareous and granites in Iran.
The study area Lokoja is the home to the confluence between Rivers Niger and Benue. Dimension stone is cut or quarried stone in accordance with specific dimensions, generally more abundant and are used in greater quantities than ore minerals in pavement and several other constructional activities. The objective of the paper is to
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.
Unit dimension stone blocks exploitation price for surface exploitation increased 3,5 times, and for underground exploitation 1,9 times from block 1 to 12. The profit of underground exploitation from block 1 to 12 is growing with a slower growth in profit in the last exploitation optimization blocks and the period of stagnation is noticed.
It also has great dimensional stone. Canada is a growing producer and consumer of all types of natural stone. Production has increased from around 559.000 tons in 1999 to 769.000 tons in 2003, the last year for
