Abstract Environmental risk can result from the interaction between human activity and the environment. Human activities can generate certain changes in the environmental components, thus inducing a potential danger for the health of people, flora, vegetation and fauna through the negative effects they have on water resources, air and soil quality, climate, microclimate, and so on. This paper presents the potable water treatment plant from Zănoaga, located in Petroșani Municipality, and highlights the potential risks related to the activity within this plant. Particular emphasis is placed on the risk to the environment and human health that may arise from improper storage and handling of liquid chlorine tanks, chlorine being a toxic gas if found in high concentrations in air, water or soil.

Abstract Land reclamation of previously mined regions has been incorporated in the mining process as awareness of environmental protection has grown. In this study, we used the open-pit coal mine Oslomej in R. N. Macedonia to demonstrate the activities related to the monitoring process of the study area. We combined the Google Earth Engine (GEE) computing platform with the Landsat time-series data, Normalized Difference Vegetation Index (NDVI), Random Forest (RF) algorithm, and the LandTrendr algorithm to monitor the mining impacts, land reclamation, and the solar farm growth of the coalfield region between 1984 and 2021. The data from the sequential Landsat archive that was used to construct the spatiotemporal variability of the NDVI over the Oslomej mine site (1984-2021) and the pixel-based trajectories from the LandTrendr algorithm were used to achieve accurate measurements and analysis of vegetation disturbances. The different land use/land cover (LULC) classes herbaceous, water, mine, bare land, and solar farm in the Oslomej coalfield area were identified, and the effects of LULC changes on the mining environment were discussed. The RF classification algorithm was capable of separating these LULC classes with accuracies exceeding 90 %. We also validated our results using random sample points, field knowledge, imagery, and Google Earth. Our methodology, which is based on GEE, effectively captured information on mining, reclamation, and solar farm change, providing annual data (maps and change attributes) that can help local planners, policymakers, and environmentalists to better understand environmental influences connected to the ongoing conversion of the mining areas.

Abstract The article shows that when dealing with many enterprises in mining areas, it is necessary to search for methods of efficiency, ways of maximizing the utility of their operation in accordance with the requirements for the consumption of useful mineral substances, primary energy resources and energy and in relation to their production potential. Clustering in the complex system of mining and energy resources is an approach that refers to geographical concentrations of interconnected companies and institutions in a certain field (mining and energy), related industries and entities for competition. Mainly, the authors deal with issues related to conceptual approaches related to clustering, anthropogenic impacts and mining/energy clustering, the delimitation of “clusters - links - infrastructure” alignments for the promotion of the mining and energy industry / economy in a collaborative regime. The conclusions are useful to the developers of strategies, tactics and programs in the field of the new industry and mining/energy economies in Romania and in other reference countries studied by the authors from the perspective of the article’s theme.

Abstract The smoke behaviour and smoke stratification of a fire in a mine drift will be one of the decisive factors affecting the risk to mining personnel during a fire. This paper studies the smoke stratification in a mine drift with multiple objects downstream of the fire, at varying distances and number of objects. Data for the study was provided from earlier model-scale fire experiments and CFD modelling was performed for in-depth analysis of specific phenomena. It was found that at considerable downstream distances from the fire, the smoke stratification differences were significant, reflecting the high impact of multiple objects. With an increasing distance between the objects downstream, an increased degree of mixing and decreased stratification occurred. With an increasing distance between the burning object and the second object, the smoke layer will descend further before encountering the object and the smoke stratification on the upstream side of the second object will decrease. The increased mixing of the hot gases flowing from the burning object will have a more significant effect on the overall stratification due to the higher temperatures. An increasing number of objects downstream will not by itself lead to increased stratification, with shorter distances between the objects and an increasing number of objects, the smoke stratification may instead be retained for a longer distance. An increasing flow velocity will result in decreasing stratification found foremost downstream of the burning object, as the tilt of the plume will increase and interact increasingly with the second object.

Abstract The rapid development of renewable energy sources, which has been going on for the last two decades, allows now the elimination of the coal use for power generation. Nevertheless, coal will continue to be used in key-industrial sectors, such as steel and cement production, which are crucial for maintaining the living standards of modern society. The future remains doubtful for coals of poor quality characteristics, such as lignite, which is used almost exclusively for power generation purposes. The present study aims to show that, even in the case of lignite, the transition to a zero-carbon economy must be decoupled from the mines closure. In this context, a combined SWOT–AHP analysis was conducted in order to compare seven potential non-energy uses of the lignite produced in the mines of Western Macedonia region, based on six criteria that are in line with the framework set by the European Union for the selection of the best technologies for every site-specific case. This comparison showed that the most promising technologies are related to the production of organic fertilizers and soil amendments, raw materials and products for the construction industry, activated carbon, and graphene. These technologies may contribute to the achievement of socioeconomic and environmental targets that are critical for the just transition of Western Macedonia region to a new, sustainable productive model.

Abstract The unprecedented increase, in the last decades, of risks, hazards and threats to the vital objectives of states and international bodies, simultaneously with the increase in their number and vulnerability, led to the sedimentation and establishment of the new concept generically called critical infrastructure. The sites where explosives are manufactured, stored and used can be considered as critical infrastructures, especially taking into account the criterion of the extent, the amplitude of the effects of an explosion produced but also the possible severity on the economic activity, the public and the environment. From this perspective, this article presents an analytical tool for modeling the dispersion of material fragments generated by the detonation of explosives based on the quantification of the impact of the throwing speed and the mass of the material fragments, taking into account the type of material and the loading conditions of the resulting debris. The developed tool resorts to the use of a statistical function, namely the probability density function for modeling different types of fragments resulting from explosion-type events.

Abstract The Antonio polymetallic ore body is part of the Baița Plai ore deposit. Below the XVIII horizon, it has a medium slope, a height of approx. 81 m, an average extension of 200 m and a thickness varying from 4 to 36 m. Above this horizon, the orebody was mined in horizontal slices with integral backfill and the first 9 m high sublevel with rooms and pillars. In depth, below this sublevel, 6 more sublevels with a height of 12 m are mined with sublevel caving mining method. The design of the opening, preparation and exploitation of the deposit was carried out for a production capacity of 100 k tonne/year.

Abstract Monitoring the displacements and settlements of tailings deposits is necessary due to stability problems that may arise over time. The paper deals with the monitoring by means of topographical measurements of two tailings deposits located on a site in Simionești village, Cordun commune in Neamț county. Topographic measurements are used to monitor the movement of landmarks located on these deposits and the settlement behavior of the deposit, so that any stability problems can be detected in time.
