Large panoramic photo showing a long, black conveyor belt stretching diagonally across the center of the frame, viewed from above. The conveyor is slightly soiled with light, irregular sand stains. To the left of the belt, along its edge, there is a yellow metal safety barrier with a handrail, running upwards and to the right. To the right of the belt, metal support rollers are visible. In the background, to the right of the conveyor, there is a large, complex industrial machinery structure in yellow and blue, used for crushing materials. In the distance to the right of the conveyor, trees and a fragment of a forest are visible, while to the left of the horizon, an open mining area with visible sand and rubble heaps can be seen. The entire scene is illuminated by bright daylight, and the sky is clear and blue.
