Technical Field

The invention relates to the technical field of mine cooling, in particular to an air-conditioning room for a mine.

Background

With the increasing exhaustion of shallow coal resources, the demand for developing deep coal resources is imminent. With the increasing mining depth of the mine, the mining depth of part of the mine exceeds kilometers, the air temperature of a mining working face exceeds 40 ℃, and the working efficiency and even the personal safety of underground workers are seriously affected, so that the mine cooling engineering becomes a key for ensuring the safe production of high-temperature mines and even the development of enterprises.

Currently, there are two mainstream mine downhole cooling technologies: direct contact cooling techniques and indirect contact cooling techniques. The direct contact type cooling technology enables high-temperature air under a mine to be in direct contact with cooling water, so that the air is cooled, but due to the fact that the concentration of dust under the mine is high, the cooling water after the high-temperature air is in contact with the cooling water is polluted by the dust, the cooling water is difficult to recover, and water resource waste is serious. The indirect contact type cooling technology enables high-temperature air under a mine to exchange heat with cooling water in a pipe through the pipe wall, so that the air is cooled, but in the using process, dust is very easy to attach to the surface of the pipe wall of cooling technology equipment, the heat exchange efficiency is reduced, and the energy consumption is increased.

Because the space of the working sites such as the underground mining working surface and the like which need to be cooled is larger, no matter the direct contact type cooling technology or the indirect contact type cooling technology is adopted, the problems of long cooling water pipeline, large power consumption of a refrigerating unit, higher energy consumption of a circulating pump and the like exist. Especially for some intermittent working places under a mine or alternate working places of workers, because the working time of each worker is short, if the whole working surface is cooled, a large amount of energy is wasted.

Therefore, it is urgently needed to develop a novel mine cooling technology, which can provide a safe and comfortable environment for underground workers and reduce energy and resource consumption.
