Opis:: Coal is a strategic and essential resource that ensures quality of life, energy security and sustainable development. Being the cheapest source of energy, it is the second after oil that is used to generate 40% of the world's electricity. However, traditional and conventional coal fuel extraction can threaten human health bycontaminating air and water, harming land, and contributing to global warming. The environmental impacts associated with conventional methods of coal mining and consumption can affect all components of the environment, and these impacts may be beneficial or harmful, permanent or temporary, repairable or irreparable, and reversible or irreversible in nature. These effects require considering of changing the production and consumption of coalwithin a technological framework. Coal mining operationscan cause both quantitative and qualitative impacts on water systems in and around mining areas. This paper reviews the impacts of coal mining on water resource development. Land subsidence, disruption of hydrological channels, flooding, and contamination of water resources and depletion of water table are the major measurable impacts of mining activity on the hydrological environment.

Opis:: The movement of raw materials can be one of the most challenging tasks in open pit mining, with truck transportation representing the largest factor in mining costs and resulting in major greenhouse gas (GHG) emissions. In this study, the transportation methods of bulk materials within German hard-rock open pit mines were investigated. Approximately 450 quarries were studied for their production tonnage, lease areas, mined rock type as well as mining methods and processing equipment. The results demonstrate that 90% of the operations use truck-based transportation methods, with the remainder relying partly or completely on continuous conveyor-based systems. The installation of continuous conveyors compared to trucks represents a real alternative because of reduced dead load, reduced GHG emissions and in many cases even reduced costs. Thus, for in-pit haulage in quarries sustainable technology substitutions exist that are yet to be adopted by the German quarrying industry. As this study shows, in the future the diffusion of sustainable technologies requires site champions and large-scale case studies that demonstrate their successful introduction in the mining value chain.

Opis:: Mineral commodity prices have decreased swiftly since 2012. For example, gold price, which was above $1800 per ounce, is currently about $1250 per ounce. Price slumps were even more severe in the base metals. Furthermore, the resource degradation and complex geologic conditions give rise to operation costs. As a result, many mining operations and development projects were eventually suspended, cancelled or ceased. Environmental compliance is also another challenge to the mining industry. The fuel consumed by diesel trucks emits greenhouse gases, which are one of contributors to the global warming. In Canada, the provinces of Quebec, British Columbia and Alberta introduced carbon taxes with the objective of reducing gas emissions in attempt to mitigate climate change. In this scope, only way to stay in business for a mining company is to invest more efficient and environmental friendly production practices such that operation costs are reduced. Given that maintenance costs and energy consumption are the largest contributors to operation costs, the minimization of carbon emissions and the maximization of equipment availability would be beneficial. This paper addresses to quantify the relationship between equipment reliability and energy consumption through a case study. It shows that a maintenance policy based on equipment reliability can significantly reduce energy consumption and its associated gas emissions.

Opis:: The use of fossil fuels as sources of energy is related to the emission of pollutants into the atmosphere. The implementation of international commitments on reducing emissions requires their continuous monitoring. The main energy resources for electricity production in the world include fossil fuels, i.e. oil, coal and natural gas, and according to projections their dominant role in the market of energy resources will persist for at least the next two decades. The aim of this article is to analyse the level of differentiation of European Union member states in terms of emissions of four greenhouse gases and to identify groups of similar countries based on these criteria. Such studies will provide information that will enrich our knowledge about the contribution of each European Union country to the emissions of greenhouse gases. This article uses a taxonomic method - cluster analysis, namely the agglomerative algorithm, which enables the extraction of objects that are similar to each other from the data and then to merge them into groups. In this way, a number of homogeneous subsets can be obtained from one heterogeneous set of objects. European Union countries make up the objects of segmentation. Each of them are described by their level of greenhouse gas emissions, such as carbon dioxide, methane, nitrogen oxides and nitrous oxides. Groups of homogeneous countries are distinguished due to total emissions and due to the level of their emissions per capita. Analysis is based on annual Eurostat reports concerning greenhouse gas emissions.
