Description
Technical Field

Mineral resources in China are rich, and most of the mineral resources such as coal, metal and the like adopt an underground mining mode. With the development of economy in China, the demand on resources such as coal, metal and the like is increasingly large, shallow resources are basically exploited out, and underground mining needs to be further transferred to deep parts. However, as the mining depth increases, the temperature of the stratum also increases correspondingly, so that the problem of high temperature of the working environment in the process of mining underground resources is caused; especially, in the roadway driving face with unsmooth underground ventilation, the heat of rocks and working face equipment cannot be taken away in time, so that the high temperature of the driving face can reach 40 ℃, and the high temperature seriously exceeds the value specified by the national standard. The process of underground mining can involve the blasting, crushing, etc. of large quantities of coal rock, which can produce large quantities of coal rock dust and blast smoke. Underground mining is a relatively closed space, and dust and blast fume generated by mining on a working face can be taken away only by ventilation. And the ventilation of the single-head tunnel in the tunneling process is poor, so that a large amount of coal and rock dust and blast fume generated on the tunneling surface can not be taken away in time, the working flour dust concentration seriously exceeds the standard, and the blast fume concentration can only reach the specified condition of the national standard.
Except that the unsmooth ventilation can bring high temperature of the working surface of a deep well and high dust concentration, for a mine with a complex mine ventilation network, when the tunneling working surface of a tunnel is positioned on the main air return side of the mine, a large amount of upstream heat, dust, blast fume and the like are mixed in the air flow for supplying the tunneling working surface, and at the moment, if the high-temperature air flow containing the dust and the blast fume is supplied to the tunneling work again, the deterioration of the environment of the working surface is further aggravated, so that the problems of higher air flow temperature, higher dust and blast fume concentration and the like are caused. The wind current with high temperature can cause syncope of people, the dust concentration with high concentration can cause pneumoconiosis of people, and the blast smoke concentration with high concentration can cause the risk of poisoning of people. Therefore, how to reduce the air temperature, the dust and the blast fume concentration of the tunneling working surface of the return air side roadway and reduce the harm to the human body becomes a problem which needs to be solved urgently.
