Geothermal circulation cooling method for high-temperature and high-humidity mine

Abstract

The invention discloses a geothermal circulation cooling method for a high-temperature and high-humidity mine, and belongs to the technical field of heat damage prevention and utilization in the coal mining process. The method includes the following steps that a mine mining high-temperature heat source area is determined through exploration, and a construction area is selected; determining the arrangement position of a drill hole and drill hole construction parameters in the construction area, and constructing parallel drill holes; laying a U-shaped heat-conducting pipeline for circulating heat-conducting liquid in the drill hole, and sealing the U-shaped heat-conducting pipeline; all the U-shaped heat conduction pipelines are centralized through a cold liquid injection pipe and a hot liquid delivery pipe respectively and are connected with a water source heat pump; the water source heat pump is connected with the thermoelectric generator to finally convey output high-temperature liquid to the ground water system, and low-temperature liquid is conveyed to the working face cooling system. A high-temperature heat source area of a mine is explored, a high-temperature heat source is circularly guided out through construction drilling between the mining working face and the roadway, and mining and utilization of the heat source and dust falling and cooling of the working face are finally achieved through operation of the water source heat pump and the thermoelectric generator.

Description

technical field [0001] The invention relates to a construction method for the prevention and utilization of mine geothermal heat, in particular to a geothermal cycle cooling method for high-temperature and high-humidity mines, and belongs to the technical field of heat damage prevention and utilization in the coal mining process. Background technique [0002] Mine heat damage refers to high and low temperature encountered in the mining process of the mine, which leads to excessively high temperature at the mining face and endangers human health. At the same time, the mechanical properties of coal and rock change under high temperature conditions, which is more likely to induce accidents and threaten mine property and personal safety. It must be governed. With the increase of mine mining depth and the development and utilization of deep resources, the problem of heat damage is becoming more and more serious. At the same time, heat damage often occurs simultaneously with water...

Problems solved by technology

[0004] 1) The first category is through ventilation and cooling, heat insulation and dredging, coal seam water injection, and placing ice cubes in the roadway and personal protection.

[0005] 2) The other type is the mine air conditioning system, which adjusts and improves the climate control of the mine operating site by applying various air heat and humidity treatment methods. Although this type of method can effectively cool down, the investment cost is high and the energy consumption is huge
