Description

Technical Field

[0001] The invention belongs to the technical field of mines, and in particular relates to a dust suppression device and a method for open-pit mine excavation operations. Background Art

[0002] A mine refers to an independent production and operation unit that mines ores with a certain mining area. A mine mainly includes one or more mining workshops (also called pits, mine shafts, open pits, etc.) and some auxiliary workshops. Most mines also include a beneficiation plant (coal washing plant).

[0003] Mines include coal mines, metal mines, non-metallic mines, building materials mines, chemical mines, etc. The scale of a mine (also known as production capacity) is usually expressed in annual output or daily output. Annual output refers to the amount of ore produced by a mine each year. According to the size of the output, it is divided into three types: large, medium and small. The size of the mine should be adapted to the economically reasonable service life of the mine. Only in this way can we save infrastructure costs and reduce costs. In the process of mine production, mining operations consume the most manpower and material resources, occupy the most funds, and are the production link with the greatest potential for reducing mining costs. The main way to reduce mining costs is to improve labor productivity and product quality and reduce material consumption. In the existing mining process, there are the following problems: a lot of dust will be generated during mining, and these dusts are often treated by spraying water sources for dust suppression. Water source dust reduction will cause serious water source loss, and continuous spraying of dust reduction will cause the ground to be wet, which is not convenient for work.
