Optimisation Improvements for Narrow VeinOpen Pit …

The mining industry is often challenged with the task of evaluating narrow vein open pit deposits. A realistic mineable solution from optimisation needs to accurately represent mining dilution and the practical limitations of mining equipment. Open pit dilution is driven according to mining method and fleet selection as this dictates the selective mining …

Selective mining played a major role in saving a mine and a community's existence as well as creating a working culture that is the model for all Kumba's mines. The successes that resulted from selective mining led to receiving Kumba's highest award (it was the Gold Medal Breakthrough project of 2003) as well as the productivity award at the National …

Optimal mining cut definition and short-term open pit …

The most common workflow in short-term open-pit planning is shown in Fig. 1.First, long-term blocks (Fig. 1 a) are divided into Selective Mining Units, or SMUs (Fig. 1 b), using blasthole data.Different estimation techniques such as kriging, inverse distance estimation, or nearest neighbor (da Silva et al., 2022) are used to populate the SMUs …

Deep Unsupervised Hashing with Selective Semantic Mining

To solve the aforementioned problems, we propose a novel method named Deep Selective Semantic Mining Hashing (DSSMH). Specifically, with the prior knowledge obtained by clustering, we select semantically correct image pairs with high confidence to alleviate the guidance of wrong information and correct sampling bias in contrastive learning ...

Mobile Mining Unit | Our Solutions

The Mobile Mining Unit (MMU) represents significant progress towards the future of sustainable mining. It allows for the necessary extraction of essential minerals, while at the same time reducing impact on the local environment, and allowing sites to be quickly returned to pre-mine condition. What started as an aspirational conversation with a ...

Mining Applications

An important goal is to predict the distribution of uncertainty of selective mining units (SMUs) before any large scale data are available. The SMU size would be chosen carefully considering the mining equipment, the data that will be available at the time of mining, visual control on mining (good visual control means a smaller SMU), mining ...

Mining the TRAF6/p62 interactome for a selective

PMCID: PMC3090762. DOI: 10.1186/1753-6561-5-S2-S4. A new approach is described here to predict ubiquitinated substrates of the E3 ubiquitin ligase, TRAF6, which takes into account its interaction with the scaffold protein SQSTM1/p62. A novel TRAF6 ubiquitination motif defined as [- (hydrophobic)-k- (hydrophobic)-x-x- (hydrophobic)- …

Study on selective mining of coal and gangue and strip …

Background: China's thin and extremely thin coal seam resources are widely distributed and rich in reserves. These coal seams account for 20% of the recoverable reserves, with 9.83 billion tons of ...

Determination of the most appropriate tools of multi

Selecting the optimal mining method is one of the most critical issues in mining design. It entirely depends on different parameters, such as geotechnical, geological, economic, and geographic factors. Although many researchers have tried to apply a various multiple-criteria decision analysis (MCDA) technique to select the most …

Change of Support and the Volume Variance Relation

A selective mining unit (SMU) may be considered the smallest volume that a mining operation can select between ore and waste (Parker, 1980). Often, the SMU size is increased to account for imperfect information at the time of mining and other considerations. The SMU geometry depends on the mining method, equipment size and …
