Underground haul roads dont change and could easily allow worksites to be automated in the future, so we chose components that would open that gap for us. Additionally, the remote capability allows the machine to be operated via remote control in dangerous conditions where it might not be safe for an operator. This machine has all the bells and whistles in terms of being PDS (pedestrian detection system), remote control and autonomous ready

Analysis of the electrochemical and XPS results has shown that adsorption of 2-mercaptobenzothiazole (MBT) on copper electrodes in neutral phosphate solutions proceeds through the formation of the chemical bonds by copper (I) cations with exo-sulfur and nitrogen atoms. A protection layer formed of Cu(I)MBT complex prevents precipitation of copper (II) phosphate on a copper surface. The thickness of the surface film consisting of a complex [Cu(I)MBT] n (having probably polymeric nature), where MBT acts as at least three-dentate ligand, increases depending on the exposure time, reaching 8-9 nm after immersing for 12 h in test solution. Even in a case of the preliminary formation of copper (II) phosphate on the copper electrode at the anodic potential addition of small amounts of MBT results in complete removal of copper (II) phosphate from the surface

In this paper, the LS-SVM model of duplex inlet and outlet ball mill system is established and verified by experiments. Then, a parametric adaptive particle swarm optimization algorithm based on particle similarity function is proposed and is named HPAPSO. In this method, a particle similarity function is put forward firstly, and based on this function the dynamic adjustment algorithm of weights and acceleration coefficients of particle swarm optimization is presented. This version of PSO has the advantages of more effective exploration of the search space, easier to lead to the global optimum, and more effective in avoiding premature convergence. At last, the HPAPSO method is combined with MPC, named HPAPSO-MPC, and is applied to solve the control problem of duplex inlet and outlet ball mill system

Strong compositional gradients between the depleted cores of minerals and their rims (in direct contact with an enriched melt) may develop during initial stages of metasomatism of melting residues. The lack of significant trace element zoningeven in large, porphyroblastic Type-1 clinopyroxenes (revealed by ion probe analyses, Table 5)indicates that the mineral grains were internally homogenized by diffusion during or after metasomatism. The time required for homogenization is primarily dependent on diffusion coefficients and temperature as well as on the distance. We use here experimental data of Sneeringer et al. (1984) on Sr diffusion in natural diopside, which are consistent with Sr diffusion coefficients obtained on clinopyroxene (and amphibole) in other studies. Possible temperatures may range from 1200C for metasomatism by a silicate melt to 1100C for metasomatism by a carbonate-rich melt or fluid. The lower T values may be more appropriate in view of the experimentally determined amphibole stability field in pyrolite compositions (1050C) (Niida & Green, 1999) if it is applicable to less fertile Spitsbergen peridotites. The solution of Ficks equation given by Crank (1975) for Sr homogenization (from 45 to 181 ppm, to 95% of the final equilibrium level) to occur in a grain with a radius of 12 mm yields about 106 years for T in the range 10501100C and 104 years at 1200C. These results further indicate that the metasomatism was not a very recent event related to formation of interstitial silicate glass and carbonate

The large amount of mine tailings generated in the mining industry each year provides a large new source of raw material for utilization in the construction and building industry. The utilization of mine tailings as construction material can reduce the volume of disposable mine tailings and thus, saving the land required for the disposal impoundments and the related high monetary costs. It can also lead to a reduction in the environmental and ecological costs and lower the demand for virgin materials that would need quarrying, thus, prolonging the life of natural resources. The following section looks at the potential use of tailings in different sectors of building and construction

Probably one of the most common pieces of mining equipment, drills are an important part of the underground mining operation. Underground mining is carried out when rocks or minerals are located at a fair distance beneath the ground. But then they need to be brought to the surface. Underground specialized mining equipment such as trucks, loaders, diggers etc. are used to excavate the material and are normally hauled to the surface with skips or lifts for further processing. Drilling is normally required to place explosive charges to liberate the minerals from the overburden material. Underground mining techniques have progressed significantly over the past years, including using remote controlled machinery

In the cement industry, rotary kiln and dryer are commonly used cement equipment in cement plants, which play a very important role in the stage of clinker calcination and raw material preparation respectively. In principle, they all play a role in drying materials by using high temperatures, but their purposes are different. While cement rotary kiln can dry materials, but its main concern is not drying, but heating
