Embodiment 1
[0038] like Figure 1 to Figure 5 As shown, in the open-pit mining method of a gently inclined ore body described in this embodiment, the ore body is in an east-west direction, inclined to the south, and the inclination angle is 4 degrees. A plurality of inclined transportation channels 1 are arranged in the stope, and a horizontal buffer platform 2 with a length of at least 30 m is arranged between adjacent inclined transportation channels 1. The transportation platform 3 and the horizontal transportation platform 4 along the direction of the ore body, the excavator 7 and the transportation vehicle 6 are located in the shovel loading area 9 of the "┏"-shaped opening ditch 5; the excavator 7 excavates the blasted ore or rock and loads it into the In the car 6, after the transport car 6 is filled with ores or rocks, it is transported along the mining stratified inclined floor 14, the horizontal buffer platform 2 and the inclined transport channel 1, and then transported out of ...
