In order to reduce the horizontal crossing transportation problems between coal trucks and stripping trucks, large and small vehicles, and transport trucks and belt conveyors at key points of open pit mine in production, the separate transportation mode of underpass bridge and overpass steel trestle is proposed to optimize the open pit development transportation system, so as to solve the practical problems that the horizontal cross of transport vehicles causes vehicle blockage, affects production schedule and production safety. The results show that the horizontal crossing road can be changed into a separate type of overpass steel trestle, which can realize the classified transportation of large and small vehicles, reduce the traffic density, make vehicles with different functions go their own way, eliminate the hidden danger of traffic accidents, and improve the production efficiency. |
