Description

Multistage ventilation filtration equipment suitable for gold mine exploitation Technical Field The utility model relates to the technical field of gold mining, in particular to multistage ventilation filtering equipment suitable for gold mining. Background Gold mining is usually performed in an underground complex environment, the underground space is narrow, and the mining operation procedures are numerous. During a series of processes such as rock drilling, blasting, shoveling and transporting, a large amount of dust is continuously generated. These dust particles vary in size, with some of the fine particles being suspended in air for a long period of time. Meanwhile, various minerals contained in the gold ore undergo chemical reactions during the mining process, releasing harmful gases such as sulfur dioxide, carbon monoxide, nitrogen oxides, etc. These dust and hazardous gases, if not properly and effectively disposed of, can cause serious problems in gold mining. On the one hand, there is a great threat to the physical health of the operators. The long-term exposure to the severe working environment is very easy for operators to suffer from occupational diseases such as pneumoconiosis, respiratory diseases and the like, and not only reduces the quality of life, but also endangers life. According to the related statistics, in the gold mining industry, medical expenditure and labor loss caused by occupational health problems bring about a heavy economic burden to enterprises. On the other hand, deterioration of downhole air quality can severely impact the safety and efficiency of the production job. Dust can reduce visibility of workplaces, and increase probability of accidents, such as mechanical collision, personnel falling and the like. Meanwhile, the accumulation of harmful gases may cause major safety accidents such as explosion, poisoning and the like, and irreparable losses are caused to enterprises and staff. Currently, there are a number of disadvantages to the ventilation and filtration equipment used in gold mining. The filter system of most devices has simple design, only has basic primary or secondary filter function, and is difficult to cope with complex underground air environment. For fine dust and harmful gases, the prior filtering technology cannot achieve ideal removal effect. For example, conventional screen type filtration devices can only intercept larger particle dust, and have lower filtration efficiency for respirable particles having a particle size of less than 10 microns.
