The Contribution Of Mining Sector To Sustainable Development In Saudi Arabia, Mourad Zmami, Ousama Ben-Salha, Sultan O. Almarshad, Houyem Chekki

Journal of Sustainable Mining

The mining sector development is among the priorities of the Saudi Vision 2030. There is currently a lot of interest in the role of the mining sector in Saudi Arabia. This research contributes to this debate by empirically assessing the effects of mining on sustainable development in Saudi Arabia during the period 1980-2018. Unlike many previous studies, the three sustainable development dimensions, namely economic, social, and environmental, are jointly considered. The cointegration analysis, based on the ARDL, Gregory-Hansen, and combined cointegration tests, confirms the existence of long-run relationships between mining and all sustainable development dimensions. Furthermore, the findings lend substantial ...

Evaluating The Performance Of Extreme Learning Machine Technique For Ore Grade Estimation, Clara Akalanya Abuntori, Sulemana Al-Hassan, Daniel Mireku-Gyimah, Yao Yevenyo Ziggah

Journal of Sustainable Mining

Due to the complex geology of vein deposits and their erratic grade distributions, there is the tendency of overestimating or underestimating the ore grade. These estimated grade results determine the profitability of mining the ore deposit or otherwise. In this study, five Extreme Learning Machine (ELM) variants based on hard limit, sigmoid, triangular basis, sine and radial basis activation functions were applied to predict ore grade. The motive is that the activation function has been identified to play a key role in achieving optimum ELM performance. Therefore, assessing the extent of influence the activation functions will have on the final ...


Selection Mining Methods Via Multiple Criteria Decision Analysis Using Topsis And Modification Of The Ubc Method, Mahrous Ali Mohamed Ali, Jong-Gwan Kim 2021 Chonnam National University

Selection Mining Methods Via Multiple Criteria Decision Analysis Using Topsis And Modification Of The Ubc Method, Mahrous Ali Mohamed Ali, Jong-Gwan Kim

Journal of Sustainable Mining

Mine designers often face difficulties in selecting an appropriate mining method; however, such a method should be selected based on ore and rock characteristics. The selection of mining methods can be considered a type of multi-criteria decision making, and this depends on many factors used in the selection process. The general method used in this field is the University of British Columbia (UBC) method, which determines the criteria of the properties that are compared to determine the best and worst of several mining methods. In this paper we used as new technique which define as Technique for Order of Preference ...

Mining Engineering Faculty Publications

Bastnaesite, monazite and xenotime are rare earth minerals (REMs) that are typical sources for rare earth elements (REEs). To advance the understanding of their leaching and precipitation behavior in different hydrometallurgical processes, Eh-pH diagrams were constructed and modified using the HSC 9.9 software. The aqueous stability of rare earth elements in H2O and acid leaching systems, i.e., the REE-Ligands-H2O systems, were depicted and studied based on the Eh-pH diagrams. This study considers the most relevant lixiviants, their resulting equilibrium states and the importance in the hydrometallurgical recovery of rare earth elements (REMs). A literature ...

Experimental And Numerical Investigation Of The Effect Of Integration Of A Flooded-Bed Scrubber Into A Longwall Shearer On Airflow Along A Coal Mine Longwall Face, Sampurna Arya, Thomas Novak, Joseph Sottile

Mining Engineering Faculty Publications

Dust control is one of the most difficult challenges for underground coal mine operators, especially longwall mine operators. The most widely used dust control technologies at a longwall section are ventilation air and water sprays, whereas a continuous miner section has the added advantage of having a dust scrubber built into the continuous miner. To test the potential benefits of integrating a flooded-bed scrubber into a longwall shearer, the authors designed and built a dust scrubber system for a full-scale mock-up of a longwall shearer. The mock-up was installed in the longwall test gallery at the Pittsburgh Research Laboratory (PRL ...

Blast-Induced Noise Level Prediction Model Based On Brain Inspired Emotional Neural Network, Victor Amoako Temeng, Yao Yevenyo Ziggah, Clement Kweku Arthur 2021 University of Mines and Technology, Department of Mining Engineering, Tarkwa

Blast-Induced Noise Level Prediction Model Based On Brain Inspired Emotional Neural Network, Victor Amoako Temeng, Yao Yevenyo Ziggah, Clement Kweku Arthur

Journal of Sustainable Mining

Although a major portion of the emitted energy from mine blast is sub-audible (lower frequency), there exist a component that is audible (high frequencies from 20 Hz to 20 KHz) and as such within the range of human hearing as noise. Unlike blast air overpressure (low frequency occurrence), noise prediction from mine blasting has received little scholarly attention in mining sciences. Noise from mine blast is considered a major detrimental blasting effect and can be a menace to nearby residents and workers in the mine. In this paper, a blast-induced noise level prediction model based on Brain Inspired Emotional Neural ...

The Influence Of Pressure Drop On Gas Emissions From A Mining Shaft – An Overview, Paweł Wrona, Zenon Różański, Grzegorz Pach, Adam Niewiadomski, Tomasz Suponik

Journal of Sustainable Mining

Climate change can make an impact on the mining sector and post-mining sites. Among others, extreme weather events are connected with sudden and deep pressure drops which lead to gas emissions from an underground space to the surface through closed shafts. The tests undertaken in the frameworks of TEXMIN project lead to get measuring data of this phenomenon and will allow validating numerical models for further forecasts and mitigation means. Three examples of the results were presented. They showed that the intensity of pressure drop influences strongly on gas emissions from a closed shaft. Although the pressure drop process should ...

Laboratory Determination Of Coal Dust Cleaning Efficacy Of A Fibrous Filter For Flooded-Bed Dust Scrubber, Neeraj Gupta, Ashish Ranjan Kumar, Steven Schafrik 2021 University of Kentucky

Laboratory Determination Of Coal Dust Cleaning Efficacy Of A Fibrous Filter For Flooded-Bed Dust Scrubber, Neeraj Gupta, Ashish Ranjan Kumar, Steven Schafrik

Mining Engineering Faculty Publications

Fibrous-type dust filters are used in flooded-bed dust scrubbers to capture dust from underground room and pillar mining atmospheres. They have 10–30 layers of finely woven strands that trap particles through the interception and impaction process. A full-cone water spray is installed upstream of the filter, which floods the screen. A scrubber’s efficacy is usually measured and reported in terms of reduction in gravimetric dust concentration at a known location in a mine. This paper reports the particle-size-dependent dust removal efficiency of a fibrous filter obtained from an instrumented test-set up. A variable frequency drive and an inline ...

A Systematic Review Of The Use Of Environmental Economics In The Mining Industry, Maria Menegaki, Dimitris Damigos 2021 National Technical University of Athens

A Systematic Review Of The Use Of Environmental Economics In The Mining Industry, Maria Menegaki, Dimitris Damigos

Journal of Sustainable Mining

Environmental economics is increasingly being used in project appraisals, environmental liability estimates and design of market-based instruments. Mining, an actor capable of causing adverse effects on the environment, human health and well-being, has already been affected by these developments, at a great extent. Up to date, several research studies have been carried out to monetise the externalities of mining projects. Nevertheless, a systematic review of these publications has not been carried out, yet. This paper aims to fill this gap in the literature by investigating (i) the main non-market valuation techniques used; (ii) the main external costs or benefits of ...
