“…Some of the most critical and widespread mining impacts are related to the pollution of soil and the aquatic environment by metals and metalloids, due to the severity of the negative effects on ecosystems and on human health [4][5][6]. The environmental degradation resulting from the leaching of Potentially Toxic Elements (PTEs) and compounds, such as Polycyclic Aromatic Hydrocarbons (PAHs) from mine waste piles, as well as from acid mine drainage, is considered a major concern by governmental agencies, mining companies, and citizens [7,8].…”

Coal mining originates environmental impacts on soil and water bodies, including the leaching of Potentially Toxic Elements (PTEs) and Polycyclic Aromatic Hydrocarbons (PAHs) in mine waste piles. This research aims to identify and characterize changes induced by self-burning in Technosols from a coal mine waste pile by means of a comprehensive hydropedological assessment encompassing geochemical, mineralogical, and hydrological data, bearing in mind the potential leaching of PTEs and PAHs. The soil profile from two contiguous areas (an area with normal pedological evolution vs. an area affected by self-burning) was characterized in terms of morphological features. Each soil horizon was sampled and analyzed for geochemical and mineralogical characterization. The unsaturated hydraulic conductivity (Ki) was also measured in all soil horizons. Finally, the leaching potential of PTEs and PAHs in water was evaluated. Several changes induced by self-burning were identified in the studied Technosols: development of specific soil horizons; destruction of humified organic matter; contrasting geochemical composition, especially in the deeper horizons; mineralogical modifications, pointing to clay minerals with higher ion exchange capacity and higher specific surface by sulphates of lower structural order; diverse Ki values in the intermediate and lower part of the soil profile; and specific susceptibility to leaching of PTEs and PAHs. The research demonstrated that self-burning causes severe changes of hydropedological relevance, with influence on the leaching of PTEs and PAHs.

“…Moreover, due to the past and ongoing mine water pumping activates in the Ruhr region, water table levels in the subsurface have been significantly reduced. Currently average water table level in coal mines amounts to approximately 600 m (Brücker and Preuße 2020;Gombert et al 2018), where in some cases water levels reduced to 1200 m were observed. Such significant differences in mine water table levels will cause pore pressure disturbances and, as a result, reactivation potentials change.…”

In this study, we carried out reactivation potential analysis of discontinuities revealed from four exploration boreholes penetrating heavily faulted and folded Upper Carboniferous rock strata of the Ruhr region. We performed this study based on the notion that slip is controlled by the ratio of shear to effective normal stresses acting on a pre-existing plane of weakness in the prevailing stress field configuration. The results of this analysis were supported by indicators of localized fluid flow, both on micro- and macro-scales, which confirm relationship between secondary permeability and in situ stress state in the Ruhr region. Findings from this study, in conjunction with results of destructive laboratory testing, indicate that the steep NW–SE- and NNE–SSW-striking planar discontinuities are likely to be either close to the critical state or critically stressed in the in situ stress configuration in the Ruhr region. These planar structures, as evidenced by indicators of localized permeability, are the main fluid pathways in the studied region. The NE–SW-striking discontinuities, on the other hand, are most likely to be closed and hydraulically inactive in the prevailing stress state. Based on results gained from this study, implications for utilization of deep geothermal energy in the region were discussed.

“…To provide a safe working zone this flooding/inrush require dewatering. For example, the hard coal area of Ruhr (Germany) requires a pumping rate of 48e54 Mm 3 /a, which is significantly higher than the normal flow rate of <5 m 3 /h [57].…”

“…This rebound is either the rise in groundwater due to cessation of pumping activities also known as passive (internal flooding) or active flooding (external flooding) in which water inrush takes place [113]. In case of France, where half of coal basins are flooded, mine water of these French mines drain into surface water bodies including rivers (95%), lakes (4%) and sea water (1%) [57]. If we take an example of China, water inrush incidents can be divided into four major categories i.e.…”

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.
