Mining Equipment The Trend Of
Aug 02, 2017

Most of the deposits are mined by ordinary mechanization, Mining Equipment and mechanized mining is divided into two categories: open pit mining (including ore and sand) and underground mining. Opencast mining stripping the ore body overlying strata and then mining from top to bottom It is possible to use large-scale mining machinery, Mining Equipment safe operation, less ore loss, low dilution rate, large production capacity, Mining Equipment low mining cost, large-scale poor iron ore deposit and building material deposit. The depth of the ore body is large, the thickness of the ore body is small, the stripping workload is very large, its economic benefit is lower than the underground mining or the need to protect the surface and landscape, then the underground mining method. Mining Equipment Occurrence of complex conditions, industrial reserves of small colored And rare earth deposits in this way.In recent years, underground mines using tailings cementation filling mining method, which can effectively protect the surface and deal with tailings pollution in some countries after the development of open pit mining, Mining Equipment with the depth of mining and environmental protection requirements Increase, underground mining has increased the trend.

Special mining methods include underground physical and chemical mining and marine mining. Physical chemistry is leaching, dissolving or melting of useful ingredients, the solution or melt from the ground lift to the ground extraction. Such methods to invest in the province, quick, Mining Equipment good working conditions , Only for copper, uranium and some other metal minerals and salt, alkali, natural sulfur, etc .. Coastal shelf and the ocean floor contains a lot of useful minerals, Mining Equipment but the ocean floor of the manganese nodules are still in the trial stage. The whole mining method of mining Minerals account for a small proportion

The development of the deposit is shown in the figure, which includes two major projects: the infrastructure development project and the production of mining engineering.The mine underground development should excavate a series of roadways or channels to reach the ore body and build a complete mining production system for production and use.

(Including underground mining methods); open-pit mining includes perforation, blasting and blasting operations, such as perforation and blasting operations, as well as mining, (See open pit mining method). ③ transport, Mining Equipment will be transported into the transport container of ore transported to the concentrator or mine (see mine upgrade, mine transport, open pit transport). ④ management roadway pressure, And the open-pit mine slope. ⑤ in the ore transport process, through the mine, stack, the ore mix, Mining Equipment to ensure the quality of the production of ore stability. ⑥ roadway excavation and stripping the output of waste rock abandoned to waste rock Field.

Due to the different geological conditions of the deposit and the technical conditions of the mine, the mining methods are numerous, Mining Equipment different mining methods, their mining process, mining machinery and equipment, mining area roadway arrangement and mining order are also different.Mine mining method is improperly selected, Mining Equipment will long-term impact of mine production Of the technical indicators and economic benefits of the major production processes have to choose the appropriate machinery and equipment in order to obtain the best economic results.
