Abstract

The invention discloses a system for reducing the mine temperature by use of constant-temperature water bearing formation. The system comprises a first circulating water pump, a second circulating water pump, a third circulating water pump, a constant-temperature water bearing layer, a mining area low-temperature water sump and a tunneling roadway low-temperature water pipe and / or stope face low-temperature water pipe, wherein a water outlet of the tunneling roadway low-temperature water pipe and / or stope face low-temperature water pipe is connected with a water inlet of the constant-temperature water bearing layer through the first circulating water pump; a water outlet of the constant-temperature water bearing layer is connected with a water inlet of the mining area low-temperature water sump through the second circulating water pump; and a water outlet of the mining area low-temperature water sump is connected with a water inlet of the tunneling roadway low-temperature water pipe and / or stope face low-temperature water pipe through the third circulating water pump. According to the invention, a constant-temperature water source in the formation is used as the main cold water source for reducing the mine temperature, and an auxiliary mine temperature reducing device is adopted at the same time to achieve the aim of preventing heat damage of a mine. The system saves energy and has high value in industrial application.

Description

technical field [0001] The invention belongs to the formation energy storage technology in the field of mine cooling, and in particular relates to a system for cooling mines by using constant-temperature water-bearing formations. Background technique [0002] With the increase of mine mining depth, mine thermal damage has become one of the problems in deep resource mining. It directly threatens the health and personal safety of miners, and seriously affects the mining efficiency of mines. Article 102 of the "Coal Mine Safety Regulations" stipulates that the air temperature of the driving face of the production mine shall not exceed 26 °C, and the air temperature of the mechanical and electrical equipment chamber shall not exceed 30 °C; . The air temperature of the mining face exceeds 30°C, and the air temperature of the electromechanical equipment chamber must not exceed 34°C, and the operation must be stopped. [0003] At present, there are two main ways to deal with mine...
