Abstract

A mine local cooling device, including fan, air duct, water inlet pipe, water pump and cooling chamber, the top of the cooling chamber is provided with a spray device, and the cooling chamber is provided with an air inlet and an air outlet, wherein: the fan communicates with the air inlet through the air duct Connection, the water inlet pipe is connected with the spray device, the water inlet pipe is provided with a water pump, and the air outlet is connected with the working surface through the air cylinder. The cooling method includes the following steps: start the fan, let the high-temperature air in the mine flow into the cooling chamber through the air duct through the air inlet; The high-temperature air exchanges heat to form a cooling air flow and a water source after heat exchange. The cooling air flows into the working surface through the air outlet, and the temperature of the cooling air flow is controlled according to the cooling requirements to achieve local cooling. The device of the invention has simple structure and convenient operation, and the cooling method can avoid economic losses and accident hazards caused by high temperature underground in coal mines, and at the same time realize energy saving and emission reduction, and have high economic benefits.

Description

[0001] Technical field: [0002] The invention belongs to the technical field of mine cooling, and in particular relates to a mine local cooling device and method. [0003] Background technique: [0004] Due to the rapid growth of my country's economy, the demand for energy is increasing, especially the gap in coal-based energy demand will continue to increase, and the number and output of mine mining will continue to increase. The minerals in the shallow part of the growth are constantly decreasing and changing, which has led to the gradual development of the mine in the deep direction, and the depth of the coal mining face and the driving face of the coal mine is also deepening. Therefore, the problem of high temperature in mines has become inevitable, and mine heat damage has become another major disaster after the five major disasters of gas, roof, dust, water and fire. Therefore, it is of great significance to study the cooling technology of high temperature mines. [000...
