Abstract: Abstract: The coal transportation line in the late mining area of Datong Tashan Mine is 13km long. The long transport route and more links resulting in reduced reliability of the transportation system. To solve the problem of mine coal cache, five oblique coal bunkers are arranged on the west side of the +1070m horizontal tape lane. Each coal bunk is 10m in diameter, the angle of inclination is 60° and the vertical height is 46m. The inclined coal bunker is constructed by the reverse well drilling rig, which reduces the construction period. The design and construction of the oblique bunker system has realized the purpose of coal buffering, improved the management efficiency of auxiliary transportation and the reliability of coal transportation system. It has reference significance for the design and construction of similar large-capacity buffered inclined coal bunker.
