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.

Tytuł:: The forecast of mining-induced seismicity and the consequent risk of damage to the excavation in the area of seismic event

Opis:: The Central Mining Institute has developed a method for forecasting the amount of seismic energy created by tremors induced by mining operations. The results of geophysical measurements of S wave velocity anomalies in a rock mass or the results of analytic calculations of the values of pressure on the horizon of the elastic layers are used in the process of calculating the energy. The calculation program which has been developed and adopted has been modified over recent years and it now enables not only the prediction of the energy of dynamic phenomena induced by mining but also the forecasting of the devastating range of seismic shock. The results obtained from this calculation, usually presented in a more readable graphic form, are useful for the macroscopic evaluation of locations that are potential sources of seismic energy. Forecasting of the maximum energy of seismic shock without prior knowledge of the location of the shock's source, does not allow shock attenuation that results from, for example, a distance of tremor source from the excavation which will be affected by seismic energy, to be taken into consideration. The phenomena of energy dissipation, which is taken into account in the forecasts, create a new quality of assessment of threat to the excavation. The paper presents the principle of a method of forecasting the seismic energy of a shock and the risk of damage to the excavation as a result of the impact of its energy wave. The solution assumes that the source of the energy shock is a resilient layer in which the sum of the gravitational stresses, resulting from natural disturbances and those induced by the conducted or planned mining exploitation, is estimated. The proposed solution assumes a spherical model for the tremor source, for which seismic energy is forecasted as a function of the longwall advance and the elementary value of seismic energy destroying the excavation. Subsequently, the following are calculated for the forecast of the seismic energy of a shock with the defined location of its source: value of the coefficient l of dispersion/attenuation of seismic energy and the flux of seismic energy at predetermined distances r from the tremor source. The proposed solution for forecasting the seismic energy of tremors and the level of risk of damage to the excavation during the functioning of mining operations is helpful in the development of bump prevention. Changing the intensity of mining operations enables the level of the seismic energy induced by the operations both at the stage of its development and during the excavation of a seam using the longwall method to be “controlled”. The presented solution has been produced for an area disturbed by the mining of coal seam 510 in the hard coal mine, Jas-Mos. An original program developed by CMI was used for the calculations.

Opis:: Decarbonisation of the European economy is one of the most important megatrends that will shape economic and social development in the coming years. This paper discusses the basic concepts of decarbonisation in terms of climate change, the history of this idea development and the legal basis introduced in the European Union, including key European documents and tools influencing the process, like ETS or CO2 emission allowances. Background on decarbonisation has been presented as a European roadmap to achieve a low-carbon economy in Europe. In the article the main assumptions of the EU strategy papers like Clean Energy for All Europeans or the European Green Deal are presented. Casus Silesia indicates the basic problematic issues that coal regions will have to tackle to due to the transition away from coal. For European societies, the new environmental policy of the European Commission means the intensification of activities to reduce greenhouse gas emissions and switching the economy to low- or zero-carbon energy sources and technologies. The decarbonisation of the economy is an ongoing process which has been gaining momentum in recent years. The coal transition is a huge challenge, particularly for Poland.

Opis:: Coal pyrolysis is a complex process involving a large number of chemical reactions. Pyrolysis is a key step in all coal conversion processes. The Distributed Activation Energy Model (DAEM) is a state-of-the art approach to the problem of predicting the amount of volatile released versus activation energy or time. The distribution of mass released is usually assumed to be Gaussian. We present an inverse iterative approach together with a smoothing function to estimate the underlying distribution directly from volatilisation data.
