Abstract

Recent years paved the way for progress focused on maximising the financial and political profits, leading in consequence to a social and economic crisis and environmental disasters. In response to those negative impacts, the concept of sustainable development appeared, understood as the need to improve life quality at the same time retaining social balance, bio-diversity of species and the variety of natural resources.

A society that is active and has a full awareness of those issues will play a major role in sustainable development. On one hand, it will control the impacts the economy has on the environment, whilst on the other, the condition of the social capital guarantees the continuity of the progress envision and planning of its implementation.

Protection of old underground sites is in line with the principles of sustainable development. Well preserved underground sites opened to visitors are a part of the cultural heritage, ensuring that historic, cultural , natural and utility values are maintained. Recently a great deal of attention has been given to revival and revitalisation of old historical underground sites and giving them a new function. Revitalisation and preservation of old abandoned excavations is a most complicated process aimed at restoring the functional utility of abandoned or disused infrastructure.

Practical design should envision activities well in line with natural processes. Underground sites being preserved and adapted have to be visitor - friendly and acceptable, being a vital component of cultural heritage viewed in the context of sustainable development. Engineering problems involve not only the practical application of science, but also the way the world is defined. That is why the social and even spiritual aspects of revitalisation projects are recalled: recreation of human interactions with the nature and with the entire surroundings.

Underground tourist routes should be harmonised with land development in the area and the residence patterns that have emerged over centuries. Well - preserved and protected excavations are the relics of the past, are part of the cultural heritage and become a rich source of knowledge about history.

Abstract

This paper describes an effective approach to select suitable plant species for reclamation of mined lands in Chadormaloo iron mine which is located in central part of Iran, near the city of Bafgh in Yazd province. After mine’s total reserves are excavated, the mine requires to be permanently closed and reclaimed. Mine reclamation and post-mining land-use are the main issues in the phase of mine closure. In general, among various scenarios for mine reclamation process, i.e. planting, agriculture, forestry, residency, tourist attraction, etc., planting is the oldest and commonly-used technology for the reclamation of lands damaged by mining activities. Planting and vegetation play a major role in restoring productivity, ecosystem stability and biological diversity to degraded areas, therefore the main goal of this research work is to choose proper and suitable plants compatible with the conditions of Chadormaloo mined area, providing consistent conditions for future use. To ensure the sustainability of the reclaimed landscape, the most suitable plant species adapted to the mine conditions are selected. Plant species selection is a Multi Criteria Decision Making (MCDM) problem. In this paper, a fuzzy MCDM technique, namely Fuzzy Analytic Hierarchy Process (FAHP) is developed to assist chadormaloo iron mine managers and designers in the process of plant type selection for reclamation of the mine under fuzzy environment where the vagueness and uncertainty are taken into account with linguistic variables parameterized by triangular fuzzy numbers. The results achieved from using FAHP approach demonstrate that the most proper plant species are ranked as Artemisia sieberi, Salsola yazdiana, Halophytes types, and Zygophyllum, respectively for reclamation of Chadormaloo iron mine.

Abstract

Denmark is among the leaders who change their energy policy to guarantee its stable and sustainable character. The consistent pursuit of an energy policy enabled the country to lower both the level of its energy consumption and greenhouse gas emissions, while providing grounds for economic development. The study demonstrates that the main factors which led to the transition of Danish energy policy were the oil crisis of the 1970s as well as public expectations regarding their energy policy which was to be based on the concept of stability and sustainability.

Horizontal well has been widely used as a solution for oil reservoir with underlain strong water drive. The advantage of horizontal well over vertical well is to increase the reservoir contact and thereby enhance well productivity. Because of that, horizontal well can provide a very low pressure drawdown to avoid the water coning and still sustain a good productivity. However, the advantage of the large contact area with reservoir will soon become the disadvantage when the water breakthrough into the horizontal well. The water cut will increase rapidly due to the large contact area with reservoir and it may cause the productivity loss of the whole well. Therefore, keeping the horizontal well production rate under critical rate is crucial.

However, existing models of critical rate either oversimplify or misrepresent the nature of the WOC interface, resulting in misestimating the critical rate. In this paper, a new analytical model of critical rate is presented to provide accurate calculations on this subject for project design and performance predictions.

Unlike the conventional approach, in which the flow restriction due to the water crest shape has been neglected; including the distortions of oil-zone flow caused by the rising water crest, the new analytical model gives an accurate simultaneous determination of the critical rate, water crest shape and the pressure distribution in the oil zone by using hodograph method combined with conformal mapping. The accuracy of this model was confirmed by numerical simulations. The results show that neglecting the presence of water crest leads to up to 50 percent overestimation of critical rates.
