Example Embodiment
[0011] In the coal seam of the open pit end bank 1, set up a transportation roadway that continuously extends with the advancement of the stripping face to become the end bank roadway 2. The end bank roadway is connected to the open pit 4 through the connecting lane 3, and the end bank roadway passes through the inclined shaft 5. It is connected to the ground transportation system 6, namely, the open pit, connecting lane, end gangway, inclined shaft, and ground transportation system are connected in sequence. Belt conveyors are laid in the chute or connecting lane, end gangway, and inclined shaft, according to the transportation volume. Determine the belt conveyor with the corresponding bandwidth, and the cross-sectional dimensions of the connecting lane, the end side roadway and the inclined shaft are determined according to the technical parameters of the belt conveyor with different bandwidths. The transportation process of coal is: after the coal is crushed by the crushing s...
