Abstract

The invention provides a mining scheme optimization method based on an open-pit mine partitioned mining process. The optimization method comprises the following steps that S1, an ore deposit geological model, a stope dump current situation model and resource mining conditions being analyzed; S2, determining the form and parameters of the slope; S3, optimizing the shape and parameters of the side slope of the refuse dump; S4, delineating a mining boundary, dividing mining areas and determining a mining sequence scheme; S5, determining a mining and discharging scheme of the end slope of the current mining area and the end slope of the adjacent mining area; S6, determining a stripping and mining program, a mining interval transition connection scheme and a stope, and making a waste dump construction and development plan; and S7, compiling a mining and discharging project progress plan and an implementation scheme. The method is advanced in technology, economical, reasonable, safe and reliable, and the purposes of shortening the transportation distance, reducing the stripping ratio and reliably continuing the productivity can be achieved.

Description

technical field [0001] The invention belongs to the technical field of open-pit mining, and in particular relates to a method for optimizing a mining scheme based on the open-pit mine partition mining process. Background technique [0002] Coal open-pit mining has many unique advantages: huge production volume, the largest annual output has exceeded 30 million tons; recovery can reach more than 95%; from the perspective of labor productivity, the labor productivity of all employees is as high as 100t / worker; and the production cost It is also relatively low; it has good working conditions, and at the same time has the characteristics of high mechanization and centralization, which provides convenient conditions for the realization of modern management and is conducive to the integration of open-pit coal mine production and the reconstruction of the ecological environment. The open-pit coal mines mainly developed in my country basically belong to near-horizontal occurrence, t...
