Description

Colliery is heat dissipation wind window in pit

Technical Field

The utility model relates to a coal mining technical field, especially a colliery is in pit with heat dissipation wind window.

Background

Coal mines are areas where humans mine coal resources in coal-rich mining areas, and are generally divided into underground coal mines and opencast coal mines. When the coal seam is far from the ground surface, a tunnel is usually dug to the underground, so that the coal is a mineworker coal mine. When the coal seam is very close to the earth surface, the coal is generally excavated by directly stripping the earth surface, which is an open pit coal mine. Most coal mines in China belong to underground coal mines. Coal mines encompass a large area above and below ground and related facilities. Coal mines are reasonable spaces excavated by humans when excavating geological formations rich in coal and generally include roadways, wells, and mining surfaces, among others. Coal is the most predominant solid fuel, one of the combustible organic rocks. It is formed by that the flourishing plants grown in a certain geologic age are gradually piled up into a thick layer in a proper geologic environment, and are buried in the water bottom or silt, and then are subjected to the natural coalification action in a long geologic age. In the geologic period around the world, the most coal is produced in formations of drumbeat, pilary, jurassic and Tertiary, which is an important coal-forming era. The carbon content of coal is generally 46 to 97%, brown to black, and has a dull to metallic luster. According to the coal gasification degree, the coal can be divided into four types, namely peat, lignite, bituminous coal and anthracite, and a heat dissipation air window is usually arranged in an underground coal mine to avoid overhigh temperature.

However, the size of the ventilation opening of the air window cannot be adjusted in the use process of the existing heat dissipation air window of the underground coal mine, and a large amount of dust is easy to float out of the external environment and pollute the environment in the process of ventilation and heat dissipation.

Therefore, a heat dissipation air window for underground coal mines is provided.
