the determination of the ultimate pit limit (upl) is the first step in the open pit mine planning process. in this stage that parts of the mineral deposit that are economic to mine are determined. there are several mathematical, heuristic and meta-heuristic algorithms to determine upl. the optimization criterion in these algorithms is maximization of the total profit whilst satisfying the...

Due to uncertain nature of grade in ore deposits, considering uncertainty is inevitable in geological modelling of resources and mine planning. In other words, uncertainty in grade of mineralized materials, is one of the most significant parameters need attention in mine planning. In this paper, a comparative procedure utilizing Sequential Gaussian Simulation (SGS) and traditional Ordinary Krig...

Coal is an abundant resource which can be used to produce low-cost energy; however, its usage causes great environmental damage. Before mineral coal used, it must processed remove tailings. These tailings contain pyrite and accumulate in large dumps, presenting significant liabilities, such as acid mine drainage. Another industry that generates liabilities the chrome-plating industry, mainly be...

In the past 15 years, there has been a major safety improvement in the Australian mining industry. Part of this change can be attributed to the development and application of risk assessment methods. These systematic, team-based techniques identify, assess and control unacceptable risks to people, assets, the environment and production. The outcomes have improved mine management systems. This p...

Healthcare data from the Arizona Health Care Cost Containment System, Arizona’s Medicaid program provides a unique opportunity to exploit state-of-the-art data processing and analysis algorithms to mine data and provide actionable findings that can aid cost containment. Our work addresses specific challenges in this real-life healthcare application to build predictive risk models for forecastin...

Machine intelligence is attracting increasing attention from both industry and academia. However, the problem of how to make machines innovate novel hypothesis is underexplored. Automatic hypothesis generation can effectively shorten research process. In this work, we try to build an embedding based genetic algorithm to learn “experience” from past data, mine latent semantic information, and th...

this study was carried out for the purpose of investigating the issue of tailings dams as a potential source of contamination by trace elements in soils at the sidi bou othmane mine in the marrakech region, morocco. soil samples taken from depths of up to 15 cm and within a radius of 50 m from the tailings dams, were analyzed for cd, cu, pb and zn using atomic absorption spectrometry. average c...

Bitcoin, a decentralized cryptocurrency, has attracted a lot of attention from academia, financial service industry and enthusiasts. The trade-off between transaction confirmation throughput and centralization of hash power do not allow Bitcoin to perform at the same level as modern payment systems. Block Advertisement Protocol is proposed as a step to resolve this issue. The protocol allows bl...

Given the large expenditures on capital equipment characteristic of mining, technology developers and users alike place a very high priority on improving equipment productivity. Proper maintenance is essential to maximizing both availability and productivity. At the same time, maintenance services are a major cost element of all mine operations.1 Accordingly, after process optimization, equipme...
