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...

The purpose of this study was to evaluate the large-scale structure, and hence available reserves, of the Lower Cretaceous Luscar Formation near Mountain Park, in the Foothills of Alberta. Coal resource evaluation clearly requires information on the mineable tonnages, as well as the grade, of the coal strata. In open pit mining, the volume of coal economically extracted from a seam is directly ...

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...

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...

The mining planning and design were carried out in PT. Tanjung Alam Jaya, a coal company South Kalimantan. intends to re-mine the Pit X area requires comprehensive mine approach achieve its objectives. study focuses on long-term planning, specifically optimizing pit while considering company's specified stripping ratio limit calculating potential reserve volumes. research aims develop an optimi...
