Abstract

There were three seam roadways set in Guantun Mine.In order to form a system,five air bridges designed for the three mining gateways of the first coal mining face in the mine could realize the connection with the mine roadway.There were slow construction,difficult controlled quality and other problems existed in the five air bridges.The paper proposed that the level of the connection gateway of the miming gateway should be raised to realize the crossing with the mine roadway.The air returning gateway would cross over the mine roadway with the connection gateway,would be favorable to the layout of the belt conveyor for the gateway driving and could realize the optimization of the mining gateway.An optimization was conducted on the right angle connection between the mine roadway and the mining gateway.
