4、 Mine cooling and dust removal complete set project

*The main heat sources in coal mines include: heat release from surrounding rock in tunnels, heat release during coal transportation, compression heat from downward (or upward) airflow, heat generated during the operation of mechanical and electrical equipment, oxidation heat release, and other heat sources. Due to the depth of mining, the ambient temperature at -925 meters level exceeds 37 ℃, making it a second level heat hazard zone. The entire system is composed of a ground refrigeration system, an ice water system, and an underground cooling and dispersing system. In reality, the underground cooling and dispersing system is an open system, where the return water flows back to the melting ice pool. The dust prevention water in the mining area, which is a small amount of water, can be connected from the cold water supply pipeline for dust prevention and spray cooling on the working face, effectively reducing the temperature of the underground environment and improving production efficiency. Ensure safe underground operations.

*It is to establish a refrigeration station near the wellhead on the ground, and generate low-temperature refrigerant of -5 ℃± 1 ℃ through refrigeration units or other pre cooling devices. By exchanging heat with purified water through plate heat exchangers, the water is cooled to 2 ℃± 0.5 ℃ and transported to the underground of the mine through pipelines. Directly spray chilled water onto the work area through a nozzle

*Low temperature water with a temperature of 2 ℃± 1 ℃ is transported by a cold water pump to the pipeline installed in the mining face machine roadway, and the chilled water is directly sprayed onto the working area through a nozzle to achieve cooling underground in the coal mine. Not only does it have cooling and dust removal effects, which traditional mine cooling cannot achieve. This process has low operating costs, good cooling effects, and does not pollute the environment.
