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.

Opis:: The mining industry is showing increasing interest in using renewable energy (RE) technologies as one of the principles of sustainable mining. This is witnessed in several pilot projects in major mining countries around the world. Positive factors which favor this interest are gaining importance and negative barrier factors seem to be less relevant. For a mine operator, the switch from fossil fuel to RE technologies is the outcome of decision making processes. So far, research about such decision making on the use of RE in mining is underdeveloped. The purpose of this paper to present a practical decision rule based on a principle of indifference between RE and fossil fuel technologies and on appropriate time management. To achieve this objective, three investigations are made: (i) a case studies analysis, (ii) a comparative cost analysis, and (iii) a SWOT analysis.
