[Abstract]:The parameters of dump and the procedure of construction and development are the important factors affecting the safety and cost of draining in open-pit mine. It is of great significance to optimize the parameters and procedures for improving the economic benefit and ensuring safe production of open-pit mine. During the reform period of Yuanbaoshan opencast mine, in order to realize the inner drainage as soon as possible, accelerate the depth reduction, lead to the increase of the stripping ratio, and the capacity of the existing dump machine is insufficient, it is urgent to establish a new dump outside the truck to ensure the smooth succession of the dumping project. In this paper, the reasonable position of the dump is chosen by the method of technical and economic comparison, the stable slope angle of the dump and the final dumping elevation are determined by the rigid body limit equilibrium method, and the optimal model of the dump height is established with the aim of minimizing the stripping and transporting work of the dump, and using the method of rigid body limit equilibrium to determine the slope angle of the dump and the final dumping elevation. With the aim of minimizing the present value of the total cost of dumping, an optimization model of dumping procedure is established to optimize the parameters of the dump outside the truck in Yuanbaoshan opencast mine and the construction and development program. The research results of this paper can reduce the production cost of Yuanbao opencast mine, improve the economic benefit and ensure the smooth succession of the draining project during the period of river diversion.
