Helium-3 nuclei make up approximately 0.002% of the solar wind [7]. Solar wind particles are emitted at 300-900 km/s (or 0.5 -4.0 keV/amu) with an average flux of 3 x 1010 ion/(cm2-s) and an average speed of 450 km/s near the Earth [3], [8]. At an energy level of 1 keV/amu, 3He particles are implanted into ilmenite about 26 nm deep and the

The PT-300 D:Mine is a remote controlled mine clearing machine effective against anti-personnel and anti-tank mines. Like all FAE tracked carriers, it can operate in the most difficult conditions, on all types of terrain, even steep slopes (max 45°), in swampy areas, and areas where there is dense vegetation or stones.
Extraction (CRC ORE) has been involved in research and on-site development to extend established Mine to Mill practice by focusing on optimising metal extraction across the whole value chain. Branded Grade EngineeringTM, this work has a particular focus on gangue rejection at coarse scales, for example blasting, screening and sorting.

Quick Take: Proof-of-Work versus Proof-of-Stake. The PoW consensus secures a blockchain network via mining. Since all miners have invested time and money into mining cryptocurrency with expensive mining equipment, miners should be disincentivized from trying to cheat the system.

Discriminating the source of water inrush accurately and efficiently is necessary for water control in the coal mining industry. We combined the Fisher feature extraction and support vector machine (SVM) methods and applied this new model to the Wuhai mining area. The method extracts features from the raw data and integrated SVM, and synthetically considers …
A Miner is a type of resource extractor that automatically extracts solid resources when built or placed on top of a resource node. There are 4 types of miners available: Portable Miner, Miner Mk.1, Miner Mk.2 and Miner Mk.3. Portable Miner (see below) is an equipment that has to be held in the hand slot to be placed on a resource node. Multiple Portable Miners can be placed …

Mining - Underground, Safety, Techniques: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of …
