LIMESTONE QUARRY MINE RECLAMATION PROJECT AT MEDUSA CEMENT COMPANY, A CASE STUDY

Mining design is usually evaluated with different multiple-criteria decision-making (MCDM) methods when it comes to large open pit or underground ore mines, but it is not used on quarry sites. Since Croatia is mostly mining stone, the implementation of such methods in decision making of the quarry mine design is imperative but left out. In this paper, the PROMETHEE II and AHP decision-making methods are implemented on the quarry site to find out the best final quarry design contour. By implementing the MCDM methods, the best quarry model was chosen based on 22 different criteria parameters out of three final quarry designs. The chosen model is not only financially sound but also has the least environmental impact.

Nowadays, a significant part of cities is tackling the problems with post-mining areas. This manuscript is an original research which shows possibilities of their reclamation. The aim of the article is to present the proposal of developing the closed limestone quarry and creating a botanical garden. The proposed spatial solutions allow for creating a new, tourist and recreation space, maintaining the natural heritage. The work also assumed carrying out a dendrological inventory, in order to determine the existing dendrofl ora. The required spatial, nature and communication analyses, which illustrate the current condition of the area and defi ne further design works, have also been carried out. The main idea of the project was to maintain the particular biodiversity, combined with regional culture and its continuous development. This type of assumption aims not only at protection of endangered species. It also has a great role in shaping the awareness of natural environment of various social groups. The creation of a rainforest substitute in the Opole Botanical Garden was possible through selection of the existing afforestation, considering its adaptation as well as through liquidation and introduction of new trees, shrubs, perennial and climbing plants, which shall emphasise the tropical landscape type by their shapes, texture and colours. The project includes many elements, which reflect the general image of humid rainforests. The planned vegetation in connection with the appropriately selected architecture shall undoubtedly influence visitors’ senses, transferring them to the ‘wild’ and mysterious part of the world.

The Relationship

This literature review intends to focus on how the settlements system of the Agro Pontino, newly designed in a geographic area contiguous to the capital city and directly connected to the integral reclamation project elaborated by the agricultural economist Arrigo Serpieri starting from 1923, is narrated. The reclamation of the Agro Pontino is one of the most important territorial transformations carried out by Fascism under direct public control. Also, this case study is particularly significant due to the relationship between the capital city, Rome, as large urban centre, the new medium size cities, villages and the morphological structure of agricultural holdings, into a historical context where the concept of agricultural property is defined. Today we have an enormous number of books, paper and documents written in different historical period that can help us to understand the evolution of the Italian new towns but at the same time the large number of these materials can also make it difficult for understanding the project and its meaning through time. The aim of this paper is, therefore, to explain how to prepare a critical bibliography able to show the evolution of the reclamation project and the construction of new towns and the changing of its meaning over time. Also, thanks to this bibliography it’s possible to extract the main issues related to the Italian case study: the relationship between the existing landscape and the network of roads; the relationship between the plans for villages, towns and the architectural features of the new settlements, and finally, the role of public buildings as a system of public facilities promoting new behaviour patterns, and their bold modernist architecture symbolized the conquest of the land.

New Settlements

Between 1950 and 1956, one fifth of the Italian landscape was profoundly reshaped. According to the first ten-year plan issued by the Cassa per il Mezzogiorno, 51 aqueducts and around 3,000 km of roads would provide the necessary infrastructure to rehouse millions of farmers, while 139 new settlements and 46,450 isolated houses would result from the new subdivision of land. Besides the national funds, newly established local authorities were entrusted with the handling of all technical aspects concerning land reclamation and resettlement. Far from being the mere result of political agreements, such an impressive and multi-faceted reform process stood at the intersection of cultural debates, national ambitions and foreign ascendancies that sought substantial alternatives to modernization and urbanization. This paper highlights an off-radar case study, with the aim of presenting and understanding some of the aspects featuring in the Italian discourse on rural planning. It deals with the intervention of the Bradano Valley Land Reclamation Authority and its main consultant, Nallo Mazzocchi Alemanni, and frames their efforts in the larger and multifaceted postwar Lucanian experience. Inscribed in the contemporary debate on regionalism and planning, the technical stance of Mazzocchi Alemanni would provide the foundation upon which to unfold the interweaving of contradictory ideologies deployed by intellectuals and activists seeking to uplift the Italian Mezzogiorno.

Better Than

Drill cuttings are generally used in open pits and quarries as the most common stemming material, since these are most readily available at blast sites. The plaster stemming method has been found to be better than the drill cuttings stemming method, due to increased confinement inside the hole and better utilization of blast explosive energy in the rock. The main advantage of the new stemming method is the reduction in the cost of blasting. At a limestone quarry, blasting costs per unit volume of rock were reduced by 7%. This is obtained by increasing burden and spacing distances. In addition, better fragmentation was obtained by using the plaster stemming method. Blast trials showed that plaster stemming produced finer material than the conventional methods. In the same blast tests, +20 cm size fragments reduced to 42.6% of the total, compared to 48.7% in the conventional method of drill cuttings stemming.
