The invention discloses a forming method for a transportation road of a bucket shovel applied to an open pit coal mine. The forming method comprises the following steps of step a, blasting a rock stratum of a first area; step b, placing the bucket shovel on the leveled top surface of a blast step of the first area, and blasting a rock stratum of a second area, wherein the second area is adjacent to the first area; step c, transporting rock soil in the first area to the ground by taking a blast heap of the second area as a temporary contact road; step d, leveling the blast heap of the second area, and blasting stratums of other areas adjacent to the second area, so as to continuously form temporary contact roads. According to the invention, by arranging the blasting sequence and taking each blast area as the temporary road for transporting rock soil of the former adjacent area, the project amount for road construction is reduced, and the labor cost is reduced.
