Technical Field

The invention relates to the technical field of coal mining, in particular to an anti-retrograde protection device for overhead riding of a coal mine.

Background

Coal mines are areas where mankind is mining coal resources in coal-rich mining areas, and are generally classified into underground coal mines and open pit coal mines. When the coal seam is far from the earth surface, coal is generally selected to be extracted from underground mining roadways, which is an underground coal mine. When the distance between the coal seam and the ground surface is very short, the earth surface soil layer is generally stripped directly to excavate coal, and the coal is an open pit coal mine. Coal mine range includes large areas of above-ground and below-ground and related facilities. Coal mines are reasonable spaces that humans excavate when mining coal-rich geologic formations, and generally include roadways, shaft pits, and face formations, among others. Coal is the most predominant solid fuel, one of the combustible organic rocks. The plant is formed by gradually accumulating a plurality of plants growing in a certain geologic period into a thick layer in a proper geologic environment, burying the thick layer in water bottom or sediment, and carrying out natural coalification in the long geologic period. Mining coal mines often lay cableways.

Generally, some cableways can cause the cable box to reverse due to power, and passengers can shake violently in the reverse process of the cable box, so that the cable box has certain danger. For this reason, a protection device that prevents retrograde for colliery aerial passenger is proposed.
