Combined supporting and cooling device for high-temperature mine roadway

Abstract

The invention relates to a combined supporting and cooling device for a high-temperature mine roadway. The combined supporting and cooling device mainly comprises a hollow anchor rod, a heat insulation pipe, an isolation disc, an output hose, an input hose, a heat insulation plug and an anchor rod supporting disc. The device is internally provided with the heat insulation pipe which divides an inner cavity of the anchor rod into a backflow cavity and a heat exchange cavity. The heat exchange cavity is connected with the input hose. Heat exchange media enter the heat exchange cavity through the input hose, enter the backflow cavity through a channel in the top of the heat insulation pipe after exchanging heat with a medium (terrane) around the device, and flow back and enter a refrigeration device through the output hose connected with the backflow cavity. The isolation disc is used for fixing the heat insulation pipe. The heat insulation plug has heat insulation and sealing effects. According to the combined supporting and cooling device, the cavity of the anchor rod is effectively utilized to exchange heat with a surrounding rock, and through continuous supply of the low-temperature heat exchange media, the roadway environment temperature can be effectively decreased, and the combined supporting and cooling device is wide in application range.

Description

technical field [0001] The invention relates to the technical field of deep mine roadway support and air temperature adjustment, in particular to a high-temperature mine roadway combined support and cooling device. Background technique [0002] The depth of coal mine mining continues to increase, and the high ground temperature in the deep part directly leads to the deterioration of the mine environment and heat damage. In the process of deep mine mining, the high temperature environment seriously endangers the physical and mental health of workers, reduces work efficiency and increases the risk of safety accidents. Nowadays, there are two main ideas to solve the problem of heat damage in mines. One is to use heat insulation devices to block the heat of surrounding rocks; the other is to use air coolers to cool down the wind flow in roadways. The devices adopted by the above two ideas are unable to actively cool down the roadway surrounding rock. For high-temperature roadwa...
