Gravity Field Changes During Deep Exploitation Of The Coal Longwall And Their Relation To Stress Distribution And Seismic Activity, Łukasz Kortas
Gravity Field Changes During Deep Exploitation Of The Coal Longwall And Their Relation To Stress Distribution And Seismic Activity, Łukasz Kortas
Journal of Sustainable Mining
Mining operations cause volumetric deformations within the rock mass and changes in its density, to which the gravimetric method is sensitive. These changes are particularly well seen in periodic measurements of the local gravity field. The paper analyses the relationship between the movement of a longwall in a coal seam and the change in the distribution of the gravity field in time and space observed on the ground surface. Relative gravimetric measurements were carried out in six series between 2018 and 2020; before the start of coal extraction, with the progress of the longwall and after the cessation of mining. …
Study Of The Relationship Of Tidal Changes In Gravity With The Time Of Mining Tremors In The Area Of The Mining Longwall In A Coal Mine – Case Study In Uscb, Poland, Sławomir Siwek
Journal of Sustainable Mining
Deep mining of coal deposits in Upper Silesia Coal Basin in Poland over several hundred years has led to disturbances in the natural state of equilibrium. As a result of changes in stress distribution, mass distribution (changes in gravity forces) and deformation of the rock mass, seismic tremors with energy reaching up to 10E+09J are generated. In this paper, the time of mining tremors occurrence is linked with changes in the gravitational load of the rock mass caused by litosphere tides, which are considered to be one of the factors leading to occurrence of natural seismic tremors. The analysis used …

Journal of Sustainable Mining
The paper reviews methods and trends of numerical modelling of geomechanical processes around underground mine excavations. The most rational method of determining the additional stresses caused by the mine excavations is chosen. Mathematical modelling was performed for excavations of various cross sections and different strength of rocks. The dimensions of the inelastic deformation zone around the mine excavations have been identified. The area of the total fracture zone around the excavation, as well as the area of the roof fracture zone are calculated. The results of the fracture zone modelling are presented both as coordinates and in a graphical form. …

Socio-Ecological Analysis Of Artisanal Gold Mining In West Africa: A Case Study Of Ghana, Richard Takyi, Rasha Hassan, Badr El Mahrad, Richard Adade
Journal of Sustainable Mining
The surge in artisanal gold mining (AGM) activities and the associated environmental impact in Ghana have elicited several stakeholders' attempts to curb the problem. However, due to little understanding of the underlying issues, these efforts have been ineffective. This study aims to use a socio-ecological framework to analyze drivers of AGM activities, the environmental pressures, the state change, their impact on human welfare, and the management response as measures (DAPSI(W)R(M)) to the problem. Evaluate AGM's impact on Ghana's ability to achieve the United Nations Sustainable Development Goals (SDGs). Data were collected from relevant literature on the subject and analyzed with …
Growth Of Invasive Plant Species Communities As A Substantial Issue In Post-Mining Land Development, Paweł Olszewski
Growth Of Invasive Plant Species Communities As A Substantial Issue In Post-Mining Land Development, Paweł Olszewski
Journal of Sustainable Mining
This article concerns the issue of the appearance and growth of invasive plant species in land degraded by hard coal mining and the repercussions of this process, particularly in the context of land reclamation. These species, such as Canadian goldenrod or Japanese knotweed, which nearly always form extensive and monocultural patches of vegetation, contribute to the displacement of both native species and those introduced as part of biological restoration. In 2015, the Central Mining Institute in Katowice prepared a land development concept for a part of the area of the former KWK Paryż mine in Dąbrowa Górnicza (Upper Silesian Industrial …
The Factors Impacting The Incorporation Of The Sustainable Development Goals Into Raw Materials Engineering Curricula, Dimitris Damigos, George Valakas, Anna Gaki, Katerina Adam
The Factors Impacting The Incorporation Of The Sustainable Development Goals Into Raw Materials Engineering Curricula, Dimitris Damigos, George Valakas, Anna Gaki, Katerina Adam
Journal of Sustainable Mining
It is widely recognised and acknowledged that the mining industry, if properly operating and managed, has the potential to positively contribute to “The 2030 Agenda for Sustainable Development”. In this direction, the Raw Materials (RM) engineering education possesses a crucial role, given the need to instil in tomorrow’s mining engineers the sustainability principles. This paper explores the educational needs of the Greek RM sector and the factors constituting the RM whole value chain SDGs-education-innovation eco-system. The research follows a two-stage focus group approach. First, the perceptions, opinions and beliefs of invited stakeholders were explored in the context of semi-structured interviews. …

Application Of Synthetic Aperture Radar Interferometry To Monitor Surface Deformations Of The Trans-European Transport Network (Ten-T) – A Case Study Of The Motorways Crossing Areas Of Mining Operations In The Upper Silesian Coal Basin, Poland, Adam Smoliński, Mariusz Stawinoga, Tomasz Pindel
Journal of Sustainable Mining
Underground hard coal mining causes surface deformations. When the mining operations are conducted beneath linear objects, such as motorways, there is a risk of deformations of the axis of the road and its horizontal and vertical alignment (additional bends and vertical curvatures, longitudinal inclinations, deformations of crosssections). In the areas subjected to mining operations, mining plants conduct geodetic monitoring. Due to their labour intensity and costs, geodetic measurements are usually made only a few times a year. The article discusses the possibility of applying Interferometric Synthetic Aperture Radar (InSAR) to monitor the subsidence of the vertical alignment of motorways caused …
