The daily operations in the mining industry are still a significant source of risk with regard to occupational safety and health (OS & H). Various research studies statistical data world-wide show that number serious injuries fatalities remains high despite substantial efforts has put recent years decreasing those numbers. This paper argues next level performance will have consider transition from coping solely workplace dangers, more systemic model taking organizational risks consideration....

Mineral commodity prices have decreased swiftly since 2012. For example, gold price, which was above $1800 per ounce, is currently about $1250 ounce. Price slumps were even more severe in the base metals. Furthermore, resource degradation and complex geologic conditions give rise to operation costs. As a result, many mining operations development projects eventually suspended, cancelled or ceased. Environmental compliance also another challenge industry. The fuel consumed by diesel trucks...

The production cycle of open-cast coal mines generally includes drilling, blasting, loading, hauling and preparation activities. Individual optimization these activities does not mean that the whole system is optimized. This paper proposes a cost model considering all in mining system-wide approach to minimize total bench production. Since fragmentation size blast-hole diameter are linked system, they considered as decision variables problem formulation. operation costs then minimized by...

We explore barite-bearing lead–zinc mineral occurrences within Türkiye's Central Taurus Orogenic Belt. Remote sensing technologies, such as ASTER, ALOS Palsar, and Planet data, were used to enhance the identification evaluation of occurrences. The area, predominantly composed carbonate rocks different ages, presents geological complexities that challenge traditional exploration techniques. employ various remote methods, including band ratio techniques, minimum noise fraction, support vector...

Stope layout optimisation finds a technically producible orebody portion that maximises the profit of mining operation based on stoping method used. A three-stage stochastic model combining genetic algorithms (GA) is proposed to account for grade uncertainty. The first stage computes stope uncertainty, second creates average design and their feasibility evaluation breeds initial population, third uses GAs improve this population over generations. approach generates higher profit, less...

The production scheduling of open pit mines aims to determine the extraction sequence blocks such that net present value (NPV) a mining project is maximized under capacity and access constraints. This sequencing has significant effect on profitability venture. However, given values coefficients in optimization procedure are obtained medium sparse data unknown future events, implementations based deterministic models may lead destructive consequences company. In this article, robust...

Selection of the optimal material handling system is one most significant decisions to be made in mineral industries. Rapid economic changes and technological improvements make cost analysis a complicated process. On other hand, current low commodity prices have put greater emphasis on reduction process optimization ensure viability mining projects. In this article, two systems, semimobile in-pit crusher conveyor systems (IPCC) traditional truck shovel (TS), are compared through an iron ore...

This paper addresses the optimal blending of different available ores in such a way that total expected cost buying ore is minimized while satisfying quality specifications. The risk limitation criterion used consists simultaneous minimization variance cost. problem solved by Chance-Constrained Programming (CCP) based on multi-objective simulated annealing. technique able to deal with stochastic nature variables problem. In generic form objectives are minimize value and standard deviation as...

AbstractFrequently, alternative technically feasible mine designs and production scenarios are available for decision makers to consider. The selection of a design is then based on estimating net present values all possible, plans so as select the one with maximum value. Conventional risk sensitivity analysis also performed supporting tools. Given multiple market geological uncertainties associated mining investments, well management flexibility respond new future information, sufficiency...

Purpose This study aims to address the critical issue of machine breakdowns in industrial settings, which jeopardize operation economy, worker safety, productivity and environmental compliance. It explores efficacy a predictive maintenance program mitigating these risks by proactively identifying minimizing failures, thereby optimizing activities for higher efficiency. Design/methodology/approach The article implements Logical Analysis Data (LAD) as approach on an dataset. aim is (1) detect...
