From: Research on boundary optimization of adjacent mining areas in open pit coal mine based on calculation of sectional stripping ratio

Figure 8

Selection of the position from the east side of the second mining area to the boundary side and the construction of the stripping ratio pre-calculation model. Due to the need for more accurate computational results in the boundary regions, the calculation zones are not divided with equal intervals. On the side closer to the boundary, six calculation zones with a step interval of 40 m are allocated, while on the distant side, six calculation zones with a step interval of 100 m are assigned.
