Abstract: In order to achieve the purpose of increasing more reclamation area and dump volume in the limited dump range, the reclamation area and dump volume were selected as the evaluation index of the dump optimize design, further followed the geometric parameters' adjustment to optimize the dump design when other influencing factors were optimal. The complexity relationship between geometric parameters and evaluation index was analyzed based on the dump surface area and dump volume calculation method. When the slope was stable, according to the characteristics of the three-dimensional space model, the geometric parameters of optimal geometric model of dump design was obtained by further dividing this area. The experimental results, based on the third dump of Yuanbaoshan opencast coal belong to Pingzhuang Coal Industry Group, show that the dump optimal design have achieved the desired effects.
