Embodiment 1

[0036] The 4# and 5# ore bodies of a certain copper deposit are huge lenticular on the plane, and plate-like along the inclination, tending to the northwest, and the inclination angle is 40°~60°. Natural caving method is adopted to recover the inclined ore bodies in foreign mines. did not appear. Because the inclination angle of the ore body is relatively slow, in order to improve the mining recovery rate and reduce the production cost, the spatial arrangement structure of the ore discharge level of the ore body in the embodiment of the present invention is used to arrange the space of the ore discharge level of the footwall of the ore body. The layout structure is as follows figure 1 As shown, two sub-layers of 584m and 614m are set in the footwall of the 4# ore body, and two sub-layers of 583m and 603m are set in the footwall of the 5# ore body. The main layer and the sub-layer are arranged in a stepped manner. That is to say, the ore level of the main layer is arranged at a...

Abstract

The invention discloses a spatial arrangement structure for the ore removal level of an ore body. The spatial arrangement structure comprises a primary layer and secondary layers, the secondary layersare located above the primary layer, and the ore removal level of the secondary layers is higher than that of the primary layer. Mining is conducted through combination of the primary layer and the secondary layers, the mining range of the ore body through a natural caving method is effectively enlarged, and the mining benefits of a mine are high; and meanwhile, the difficult problems of continuous caving of high and middle sections of the extremely thick and large gentle dip ore body and heading side ore recovery are further solved, and the ore recovery rate of the heading side ore body is effectively increased.

Description

technical field [0001] The invention relates to the technical field of mining, in particular, to the spatial arrangement structure of the ore-out level of an ore body. Background technique [0002] Referring to foreign natural caving mine data, the ore is mainly produced at a single middle section level, and most of them are ore bodies with steep dip angles. However, for typical inclined thick ore bodies (the dip angle of the ore body is 40°-60°), according to the mining technical conditions of this type of ore body, if the ore is mined at a single middle level, the footwall ore body outside the caving range will It cannot be recovered by caving in the main layer, resulting in a high rate of ore loss. [0003] For the ore body outside the caving range, the traditional method is to adopt the segmented caving method for mining, but the mining sequence of the natural caving method is the bottom-up caving of the ore body, and the segmented caving method adopts top-down mining, ...
