Upward horizontal layering step-by-step mining method along strike drift

Abstract

The invention relates to an upward horizontal layering step-by-step mining method along a strike drift. The method comprises the following steps that (1) roadways outside arteries and veins of a stope are subjected to segmentation, and meanwhile, the roadways outside the arteries and veins of each segment are layered; (2) a channel is arranged on the bottommost layer of the stope of a certain line in the direction transversely penetrating through the stope for construction, and a mining drift is arranged after construction is conducted to the hanging wall of an ore body; (3) after the construction of the mining drift is completed, plate walls are arranged outside the heading wall position of the stope for filling (4) after filling is finished, coping construction transversely penetrating through the stope is changed to previous layer, and construction is conducted to the hanging wall of the ore body in the direction transversely penetrating through the stope; and (5) the steps are circulated for upward mining until the end. The method can give consideration to the aspects of production efficiency, cost, safety and the like, has the advantages of high recovery efficiency, low cost, high safety and the like, and solves the problem that the mining method for the gently inclined thin ore body cannot give consideration to the effects at the same time in the prior art.

Description

technical field [0001] The invention relates to an ore body mining method, in particular to a step-by-step mining method of upward horizontal layering along a strike route. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] The ore body is divided into medium-thick ore body and thin ore body according to its thickness, and it is divided into gentle slope and steep slope according to its inclination angle. Ore body structures with different characteristics have different difficulties due to their existence, so mining methods are not universal. , it is necessary to select a suitable mining method for a specific ore body structure type. Specifically, it has always been a diffi...

AI Technical Summary

Problems solved by technology

It can be seen from the above that the construction cost of the slab wall is high, it takes a long time, and the area of ​​the ceiling is large, which affects the safe operation. Although the production efficiency can be improved, the feasibility is poor.

[0005] It can be seen from the above that, for the ore body structure of the gently inclined thin ore body in the prior art, the mining method cannot reduce costs and ensure safe operation while taking into account production efficiency.
