Cooling method for mineral resource exploitation by means of natural cold source and application system thereof

Abstract

The invention provides a cooling method for mineral resource exploitation by means of a natural cold source and an application system thereof. The cooling method comprises the steps that 1, an earth surface water source is conveyed into an underground high-low-pressure heat exchanger; 2, low-pressure cold water obtained after heat exchange enters a cold water set, the cold water set cools air, andan existing air supply system is used for conveying the air to the operation face to cool the operation face. A pond in the application system is lower than the horizontal plane where the bottom faceof a raw water tank is located. The raw water tank, the high-low-pressure heat exchanger and the pond are sequentially connected. A valve A is arranged on a pipe A. A valve B is arranged on a pipe B.The high-low-pressure heat exchanger is connected with the cold water set. A circulating pump is arranged on a connecting pipe of an inlet of the cold water set and an outlet of a cold medium of thehigh-low-pressure heat exchanger. A shell is arranged outside the cold water set. The shell is provided with an air inlet and an air outlet. An induced draft fan is connected to the air outlet, and connected with an air supply pipe. The system has the advantages of being reasonable in design and capable of achieving effective cooling, saving energy and reducing emission.

Description

technical field [0001] The invention relates to the technical field of mineral mining, in particular to a cooling method and an application system for using a natural cooling source in mining of mineral resources. Background technique [0002] With the increase in demand for resources, mining has shifted from the surface to deep mining. In the process of deep mining, the requirements for mining operations are getting higher and higher, which makes mining difficult and costly. The main factors restricting the progress of mining are The high temperature problem on the working surface has seriously affected the work efficiency, and even seriously affected the physical and mental health of the employees, resulting in the inability to maximize the benefits. [0003] In the prior art, there are many methods for reducing the temperature of the working surface, such as ventilation technology, using various equipment to cool down the water and then cooling the downhole working surfac...

[0002] With the increase in demand for resources, mining has shifted from the surface to deep mining. In the process of deep mining, the requirements for mining operations are getting higher and higher, which makes mining difficult and costly. The main factors restricting the progress of mining are The high temperature problem on the working surface has seriously affected the work efficiency, and even seriously affected the physical and mental health of the employees, resulting in the inability to maximize the benefits

[0003] In the prior art, there are many methods for reducing the temperature of the working surface, such as ventilation technology, using various equipment to cool down the water and then cooling the downhole working surface, etc. These technologies still have some problems in the actual use process. One is The way of ventilation and cooling is more difficult to meet the requirements in the long-distance single-head excavation of deep mines, which leads to the occurrence of occupational diseases and even affects the physical and mental health of employees; second, the grade of domestic mines is low, and the investment of a large amount of equipment leads to rising costs, which is not conducive to mining; third, The operation of the equipment has an adverse impact on the environment and does not meet the requirements for energy saving and emission reduction
