Problems solved by technology

[0003] The inventor found the following problems in the existing air-cooling cooling technology: in the past, cooling air was used to cool the working surface, and the cooling terminal equipment was always set The air in the working face is composed of the air cooled by the cooling terminal equipment and the original air in the roadway. The temperature and humidity are high, which affects the effect of cooling and heat exchange on the working face

Abstract

The invention discloses a deep well high-temperature working face cold wind temperature reduction system and a method. The system comprises that an air door is arranged at an upper gateway wind inlet on the working face of the deep well; one side of the upper gateway is provided with a temperature reduction special tunnel; the air outlet of the temperature reduction special tunnel is communicated with the upper gateway; the temperature reduction special tunnel is internally provided with a temperature reduction end device; the air inlet of the temperature reduction special tunnel is connected with an air inlet. The system solves the mixed wind problem of the former temperature reduction system, effectively reduces the temperature and the humidity of the airflow which passes through the working face, improves the temperature reduction effect, gains more low-temperature and low-humidity air to enter the temperature reduction working face, and effectively improves the heat exchange efficiency of the whole temperature reduction system.

Description

technical field [0001] The invention relates to a cooling technology, in particular to a pure cold air cooling system and method for a high-temperature working face in a deep well, belonging to the field of cooling the working face in a deep well. Background technique [0002] In mine production, mine development and deployment, ventilation system design, etc. will affect the temperature and humidity of the mine air flow. A reasonable mine ventilation method will alleviate the high temperature and heat damage underground, especially when increasing the ventilation volume and reducing the air flow temperature and humidity. At this time, it can have an obvious cooling effect, which is a cooling method that is widely used in non-artificial cooling technology. Practice has shown that no matter what kind of artificial or non-artificial cooling methods are adopted to cool down the high-temperature working face in deep wells, ventilation is the most basic auxiliary way, especially ...
