Method for realizing rapid internal dumping of metal strip mine hillside mining

Abstract

The invention relates to a method for realizing rapid internal dumping of metal strip mine hillside mining, and belongs to the technical field of mining. The method comprises the following steps thatan open stope is divided into a plurality of sub-mining areas along the trend of an ore body according to the minimum distance of a single mining area determined by the minimum distance of an inner dump in the hillside mining stage of the metal strip mine; the difference of slope heights of a hillside strip mine in space is fully utilized, a primary mining area, an auxiliary mining area and a post-mining area are further divided, and the height difference between the post-mining area and the primary mining area is effectively controlled through matched mining of the primary mining area and theauxiliary mining area, so that a transportation route for connecting the post-mining area and the inner dump can be smoothly arranged. After the primary mining area is mined, the internal dumping condition can be quickly formed for the post-mining area in the sub-mining area, and after the post-mining area is mined, the internal dumping condition is created for the primary mining area and the auxiliary mining area of the next adjacent sub-mining area, so that the goals of quickly and internally dumping the metal strip mine hillside are achieved, the internal dumping service life is prolonged,and the economic benefit is improved.

Description

[0001] background field [0002] The invention belongs to the technical field of mining, and in particular relates to a method for realizing rapid inner drainage in slope mining of metal open-pit mines. Background technique [0003] my country's metal mineral resources are characterized by a large total amount of resources, but few per capita resources and insufficient high-quality resources. The current structural contradictions of many, small and scattered mine development still exist. "Green, safe and efficient" is the theme of world-class mine construction, and the full realization of mineral resources development in the green mine mode is the need for the transformation and upgrading of traditional industries. The dump site is an important part of the open-pit mine. The dump site of metal mines in my country is mainly arranged outside the stope. The external dump site occupies a large amount of land resources and is prone to landslides and debris flows. It is a major sour...

Problems solved by technology

[0006] Aiming at the problems existing in the prior art that the height difference of adjacent mining areas is large due to conventional zoning and mining methods, and the discontinuity of internal drainage causes delays in the internal drainage period and cannot be quickly internally discharged, the present invention provides a metal open-pit mine that realizes rapid mining on the hillside. The inner row method is aimed at the slope mining stage of metal open-pit mines. The open-pit stope is divided into multiple sub-mining areas according to the minimum distance of the single-mining area determined by the minimum distance of the inner dump along the ore body. In the area, make full use of the difference in the height of the slope in the open-pit hillside mine to further divide the initial mining area, auxiliary mining area and post-mining area, determine the specific range of the initial mining area according to the minimum distance of the internal dump, and pass the initial mining area Coordinated mining with the auxiliary mining area can effectively control the height difference between the back mining area and the first mining area, so that the transportation route connecting the back mining area and the inner dump can be arranged smoothly. The rear mining area in the mining area quickly forms internal drainage conditions, and after the mining of the rear mining area is completed, the inner drainage conditions are created for the first mining area and auxiliary mining area of ​​the next adjacent sub-mining area, and this cycle is repeated to achieve The goal of rapid internal drainage in slope mining of metal open-pit mines, prolonging the service life of internal drainage, improving the economic benefits of internal drainage, etc.
