The invention discloses a multifunctional mine well wall cooling device and a cooling method. The device includes a supporting device, a cooling unit and a heat energy conversion unit. Heat pipes, a number of auxiliary heating pipes arranged on the secondary heat pipes and heat exchange parts arranged in the primary heat pipes, the heat exchange parts are connected with the heat energy conversion unit; the cooling method includes setting auxiliary heating pipes on the mine rock wall of the mine roadway. The heating pipe, the supporting device and the cooling unit connect the cooling unit with the thermal energy conversion unit, start the thermal energy conversion unit, and cool down the mine roadway. The device is supported by supporting units to increase the strength of the inner wall of the mine roadway, and the cooling unit is built in the support unit to absorb and conduct heat in the mine rock mass, thereby cooling the mine roadway. The heat energy conversion unit Then utilize and convert heat energy to realize heat energy recovery; and the construction method is simple and operable.
Description
technical field [0001] The invention belongs to the technical field of mine protection construction, and in particular relates to a multifunctional mine shaft wall cooling device and cooling method. Background technique [0002] Mine roadway is a general term for various underground spaces that are excavated in different directions, at different inclination angles, according to different sections and lengths in different rocks, and serve in different ranges and for different purposes; A mine tunnel that is mined so that mine workers can extract and transport the required mineral resources to the surface. [0003] However, in some places underground, the temperature will be higher than normal temperature due to the existence of geothermal heat. The high temperature increases the difficulty of construction in the mine roadway, reduces the work efficiency of the mine workers, and the high-temperature resources in the rock mass are not collected. It is a pity to use it and wast...
