TL;DR: In this article, the impact of mining activities on the environment has been investigated in Plateau and Enugu regions of Nigeria, using a case study for areas with existing mines and the coal mines at Enugu.

TL;DR: Corrective actions are proposed that can help to avoid the occurrence of the accidents presented, through the application of occupational safety and health regulations issued by the Secretaria del Trabajo y Prevision Social, which is a government entity that is responsible for both the issuing of and compliance with those regulations.

TL;DR: In this article, the authors provide a critical review of the relative literature on slope failure incidents and other stability concerns, and also briefly present cases for which no information has been published in the past.

TL;DR: In this paper, the authors identify the potential sources of radon exhalation and its measurement in underground uranium mines to control the radiation levels within safe limits and protect miners from radiation hazards.

TL;DR: In this paper, the authors used the Samarco tailings for the synthesis of zeolite from the tailings and its application for the treatment of electroplating effluent, which can be used for the wastewater treatment.

TL;DR: Digital image analysis is carried out for monitoring the mean fragment size and boulder percentage in opencast mines of the Talcher Coalfield (India) using forty blasting datasets carried out using a highly consistent result.

TL;DR: In this article, a Hierarchical Cluster Analysis (HCA) model was constructed with a colour data map enabling the tracing of similarities between the samples of coal mine waste in the space of parameters and between the examined physicochemical parameters in the spaces of samples.

TL;DR: According to the results obtained from the testing dataset, the WNN with a single hidden layer and three wavelons produced highly satisfactory and comparable results to the benchmark methods of BPNN and RBFNN.

TL;DR: The structure and research potential of the newly created measurement and information system for observing dynamic phenomena occurring in the Earth's crust in the Upper Silesian Coal Basin in Poland as a result of mining activities are presented.

TL;DR: In this paper, an analysis of material and energy flow networks presented in the form of Sankey diagrams enabled the identification of unit processes with the biggest consumption of raw materials and energy, and the greatest amount of emissions to the environment.

TL;DR: In this article, the authors used 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.

TL;DR: In this article, the levels of multiple natural radionuclides in an aquatic system (Moulouya river, Morocco) impacted by multiple abandoned Zinc and Lead mines were determined by alpha-particle spectrometry in water and sediment samples collected along the river and in samples from three pit lakes of abandoned mines, located in the Upper Mouya catchment area.

TL;DR: In this paper, the capability of zeolites to remove natural radionuclides from mine waters and compare the removal efficiency of radium isotopes with the results obtained from the application of barium chloride solution for the same purpose.

TL;DR: An improved TOPSIS method based on experimental design is presented, which defines as Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS), which is a modified version of the UBC method that can be employed based on Excel sheet.

TL;DR: In this article, the authors present an algorithm for the current assessment of methane hazards during the exploitation of longwalls in conditions where there are methane hazards, based on the analysis of the ventilation-methane balances for longwall areas.

TL;DR: In this paper, the authors explored the educational needs of the Greek mining industry and the factors constituting the RM whole value chain SDGs-education-innovation eco-system using fuzzy cognitive maps (FCMs).

TL;DR: In this article, the geometrical relationship between the three cardinal variables of ore reserve estimation, surface area, thickness, and density, was investigated for lead-zinc mines in the Asu River Group in Nigeria.

TL;DR: In this paper, the authors present a number of design fire scenarios which were developed from risk assessments and risk analysis where a deterministic approach was implemented and where the results from earlier full-scale fire experiments in underground mines and analysis were included in the process.

TL;DR: In this article, the authors present the authors' computational methods based on Knothe's theory for the estimation of the reduction coefficient for effects which originate from mining operations performed via the application of a longitudinal structure which is sunk in to the ground.

TL;DR: In this paper, the authors evaluated twelve sub-categories of supervisors competence and knowledge level and their impact on the effectiveness of the maintenance of security in underground coal mines, and the correlation between the determined level of separate competence subcategories and their influence on the level of safety enabled the prioritization of the levels of a lack of competence in reference to proper work safety maintenance.

TL;DR: The statistical analysis carried out revealed that the BENN performed better than the other investigated methods, and can be useful in managing noise from mine blasting using site specific data.

TL;DR: In this article, an experimental application of cable bolts was performed in gateroad #165 of the "Stepova" mine, Western Donbass, Ukraine, and required instrumental control of "support-rock mass" system conditions.
