In this paper, we present an integrated model to find the optimum size of blast block that uses (i) a multi-criteria decision-making method to specify the applicable size of the mineable block; (ii) a linear programming method for the selection of the blasted areas to be excavated and in deciding the quantity of ores and wastes to be mined from each one of the selected blocks. These two methods...

The block economic value (BEV) of a single-metal deposit is calculated based on the metal content and the related costs. The common methods available for calculating BEV are just based upon the profitable elements, and the effects of undesirable elements on BEV are not considered. However, in multi-element deposits, the effects of other elements existing in the blocks on BEV should be considere...

Clustering approaches are widely used to group similar objects and facilitate problem analysis decision-making in many fields. During short-term planning of open-pit mines, clustering aims aggregate blocks based on their attributes (e.g., geochemical grades, rock types, geometallurgical parameters) while honoring various constraints: i.e., cluster shapes, size, alignment with mining direction, ...

Cryptocurrencies, as a way of extraction, are categorized into two main groups non-mineable and mineable. Bitcoin (BTC), the most famous mineable digital currency, utilizes Proof Work (PoW) algorithm for maintaining network solidarity. Its mining process is done by devices known application specific integrated circuits (ASICs), which consume electricity turn it heat. They shall operate within a...

We present a novel framework for set-valued data anonymization by partial suppression regardless of the amount of background knowledge the attacker possesses, and can be adapted to both space-time and quality-time trade-offs in a “pay-as-you-go” approach. While minimizing the number of item deletions, the framework attempts to either preserve the original data distribution or retain mineable us...

Metal price is one of the most important parameters in the calculation of cut- off grade. The cut- off grade has the main role in determination of mine layout. Mine layout actuates mineable reserve, mine life and economic profitability. Not considering the uncertainty in metal prices can lead to a non-optimal layout. In this paper optimum underground mine layout is determined by expected utilit...

In the past decade, the field of medical image analysis has grown exponentially, with an increased number of pattern recognition tools and an increase in data set sizes. These advances have facilitated the development of processes for high-throughput extraction of quantitative features that result in the conversion of images into mineable data and the subsequent analysis of these data for decis...
