Based on extensive experience in shield support design and the results of underground measurements observations, major factors influencing stability roof retreat longwall panels were determined. A practical method for assessing risk falls is presented. It a combination empirical methods expert techniques that enable investigators to determine probability potential consequences falls. This report includes an example applying one panel. The decision tool mining management when planning fall...

The mining industry needs community and regional governmental support to maintain its current activities and, more importantly, develop future projects. failure manage environmental risks in an acceptable manner during mine operation, closing post-closing periods is a critical factor. must regain reputation that has been lost over decades centuries of degradation. Several management tools (e.g., life cycle assessment, multi-criteria decision analysis, etc.) are widely applied development,...

The environmental directives within the European Union consider necessary protection, establishing strict protocols for controlling methane emissions in mining operations. On other hand, exploitation of coal mines has found degasification an end itself, providing a fuel undoubted energy value that can be easily transformed into electrical or calorific energy. All this must accompanied by control establishes extraction and prior layers as fundamental task to guarantee safety mining. Following...

The rehabilitation of post-mining sites is crucial due to the severe environmental impacts mining, including land degradation, heavy metal pollution, and loss biodiversity. Effective reclamation strategies are essential reverse these enable sustainable use. This study presents possibility a area in Velenje, Slovenia, using artificial soils made from combustion by-products amended with lignite organic compost, explores potential mine water for irrigation. approach introduces an innovative...

This paper presents a one-year forecast of European thermal coal spot prices by means time series analysis, using data from IHS McCloskey NW Europe Steam Coal marker (MCIS). The main purpose was to achieve good fit for the quick and feasible method establish transformations that better suit this marker, together with an affordable way its validation. Time models were selected because showed autocorrelation systematic pattern also number variables influence is very large, so forecasting as...

Closure and post-closure periods in underground coal mines present specific risks that have to be handled with sound management practices order achieve sustainability within the mining sector. These may negatively affect environment result hazards on surface caused by phenomena occurring rock mass after operations. One of has considered process mine closure is gas, which methane emission operations cease. This paper presents a forecast emissions conducted framework Research Fund for Coal...

This paper studies investments in new tungsten mining projects, analyzing in-depth five ready-to-go projects around the world that were presented to financial markets by listed companies obtain funds so they could start operations near future: Barruecopardo open-cut project Spain (Ormonde Mining); Kilba Australia (Tungsten Hemerdon United Kingdom (Wolf Minerals); Sangdong underground South Korea (Woulfe and King Island Scheelite, a mixed Tasmania (King Scheelite). These investment selected...

This paper presents a methodology to select the most exciting business models based on renewable energy and circular economy technologies within end-of-life coal mines help develop renewable-based sector, promote sustainable local economic growth, maximise number of green quality jobs. To achieve this goal, first, structural analysis was developed technical variables that better identify complex system. Second, morphological allowed construction scenario space. Third, multicriteria...

This paper presents a new way of valuing ecosystem services based on the price EU carbon dioxide emission allowances. Its main advantage is that it facilitates monetisation non-provisioning services, which Achilles heel current frameworks. The research approach built notion land rehabilitation and ecological restoration involve trade-offs between services. A quantitative assessment (valuation) these necessary to make sound decisions. However, using different valuation methods estimate...

CO2 Capture Ready Process, as a part of Carbon and Storage (CCS) technology, is response to international political pressure the priority European Commission reduce anthropogenic emissions since it connected with concerns regarding global warming. This currently considered an option for lessing into atmosphere. Many laboratory experiments, well pilot projects, have been carried out using different capture systems, but until now no experience from one-to-one size operational installation has...

Multi-criteria decision analysis and cost-benefit analysis, either individually or in combination, have been used as the preferred tools to develop ecosystem services valuation, presenting significant discrepancies variations between calculated values. To counteract this problem, a new framework was developed based on hierarchical weighting of non-provisioning services, using biodiversity reference service since it is easiest apprehend. Their monetisation made average price EU carbon dioxide...

This paper applies a heuristic approach to optimize the predictor variables in artificial neural networks when forecasting raw material prices for energy production (coking coal, natural gas, crude oil and coal) achieve better forecast. Two goals are (1) determine optimum number of time-delayed terms or past values forming lagged (2) improve forecast accuracy by adding intrinsic signals variables. The conclusions clearly opposition actual scientific literature: addressing variable size,...

The main purpose of this paper was to outline a novel approach for the use industrial by-products generated in coal mines and coal-fired power plants as components artificial soils. Several combustion by-products, mine waste organic materials were tested at laboratory scale reclamation areas degraded by mining activity. role soils land rehabilitation high acidic heap. results revealed that amounts matter (14.87–25.01%) nutrients soil substitutes sufficient support plant growth, i.e., N...

Coal mining and the energy industry generate large amounts of solid waste, which must be disposed in landfills lead to numerous environmental problems. This paper presents a method for creating artificial soil mixtures based on an EU-funded international research project called RECOVERY. The main idea behind proposed solution is safe use coal combustion by-products (energetic slag decarbonation lime), waste (aggregate sealing material) spent mushroom compost as components soils. Laboratory...
