A majority of continuous mining machines employ a water spray system and a machine mounted flooded-bed scrubber to suppress and capture dust during coal mining. These machine mounted dust control systems must be designed to function within the localized face ventilation system at the mining section to control both dust and methane. Spray systems can impede or improve the scrubber effectiveness ...

In open-pit mine planning, the design of the most profitable ultimate pit limit is a prerequisite to developing a feasible mining sequence. Currently, the design of an ultimate pit is achieved through a computer program in most mining companies. The extraction of minerals in open mining methods needs a lot of capital investment, which may take several decades. Before the extraction, the p...

One of the most important steps involved in mining operations is to select an appropriate extraction method for mine resources. After choosing the extraction method, it is usually impossible to replace it with another one because it may be so expensive that implementation of the entire project could be economically impossible. Choosing a mining method depends on the geological and geometrical c...

Purpose. To develop a methodology for assessing the quality of drilling-and-blasting operations when setting side to final position. In this regard, it is necessary study nature deformations in near-side masses design open-pit contours and assess seismic impact blast waves accordance with damage near far zones from boundary, as well level generated vibrations. Methodology.A at limiting contour ...

Purpose. Research into influence of drilling-and-blasting operations on the nature deformation in near-side masses design open-pit contours and assessing seismic impact blasting operations, which are basis for development recommendations rational parameters operations. Methods. The at limiting contour Kusmuryn field is studied using analysis mining-and-geological conditions tectonics rocks cons...
