Abstract
The invention discloses a kind of method that pattern occupy-place improves ore recovery rate, belong to mine underground production technique field, concretely comprise the following steps：(1) flexible bag body, is laid in Bottom of Stope position, flexible bag body size and dimension is determined as needed；(2), using pipeline by ground paste filling into flexible bag body, slurry dewatering shaping after formed occupy-place pattern；(3), explosion falls ore deposit and ventilation, after underground air condition meets related operating regulation to other safety conditions, carries out ore removal operation.This method forms pattern after being dehydrated using flexible bag body filling slurry, occupy-place is carried out in advance in Bottom of Stope position, the ore of avalanche is set to concentrate on out around mine mouth, effectively reduce the ore residual of Bottom of Stope, the purpose that pattern replaces Bottom of Stope permanent loss ore is realized, the security of ore recovery rate and ore removal operation is improved.The present invention has the advantages that working security is good, cost is low, efficiency high, technique are simple.
Description
Technical field
The invention belongs to mine underground production technique field, and in particular to a kind of pattern occupy-place improves the side of ore recovery rate
Method.
Background technology
At present, mineral resources are more and more rare, how existing minerals resource safety, efficiently, sufficiently it is mined into
For common problem.During some orebody minings, Bottom of Stope goes out between mine mouth and away from going out the place of mine mouth often
Remain substantial amounts of ore, it is impossible to produced safely, form permanent ore losses.The application of remote-controlled scraper is reduced to a certain extent
This part ore losses, but there are still the problem of ore removal equipment safety inside goaf and larger remaining ore deposit amount.
The content of the invention
It is an object of the invention to provide a kind of method that pattern occupy-place improves ore recovery rate.This method utilizes flexible bag body
Pattern is formed after filling slurry dehydration, occupy-place is carried out in advance in Bottom of Stope position, the ore of avalanche is concentrated on out mine mouth week
Enclose, effectively reduce the ore residual of Bottom of Stope, realize the purpose that pattern replaces Bottom of Stope permanent loss ore, improve
The security of ore recovery rate and ore removal operation.
A kind of method that pattern occupy-place improves ore recovery rate, is comprised the following steps that：
(1) flexible bag body, is laid in Bottom of Stope position, flexible bag body size and dimension is determined as needed；
(2), using pipeline by ground paste filling into flexible bag body, slurry dewatering shaping after formed occupy-place pattern；
(3), explosion falls ore deposit and ventilation, after underground air condition meets related operating regulation to other safety conditions, enters
Row ore removal operation.
Further, described flexible bag body material is with the good material of necessary intensity, dewatering, such as geotextiles
Deng.
Further, described slurry is the slurry that tailing cemented filling material slurry or other energy form necessary intensity.
Compared with prior art, advantages of the present invention is as follows：
The method that a kind of pattern occupy-place of the present invention improves ore recovery rate, is taken off consolidated fill slurry using flexible bag body
Pattern is formed after water, occupy-place is carried out in advance in Bottom of Stope position, the ore of avalanche is concentrated on out around mine mouth, effectively reduction
The ore removal residual ore of Bottom of Stope, realizes the purpose that pattern replaces Bottom of Stope permanent loss ore, improves ore
The rate of extraction and the security of ore removal operation.The present invention has the advantages that working security is good, cost is low, efficiency high, technique are simple.
Brief description of the drawings
Fig. 1 is that a kind of pattern occupy-place of the present invention improves the method flow diagram of ore recovery rate；
Fig. 2 is that a kind of pattern occupy-place of the present invention improves the method flow enlarged drawing of ore recovery rate；
In figure：1- ore bodies, 2- go out mine mouth, the ore of 3- avalanches, 4- occupy-place patterns.
Embodiment
Technical scheme is discussed in detail below in conjunction with the accompanying drawings.
Embodiment 1
Such as a kind of method that Fig. 1, as indicated with 2, pattern occupy-place improve ore recovery rate, comprise the following steps that：
1) flexible bag body is laid in the centre position of Bottom of Stope, flexible bag body size and dimension is according to i.e. by the ore deposit of avalanche
The requirement that stone 3 is pooled to out mine mouth 2 is determined；
2) cementitious slurry is filled in flexible bag body using pipeline, occupy-place pattern 4 is formed after slurry dewatering shaping；
3) carry out explosion and fall ore deposit and ventilation, after underground air condition meets related operating regulation to other safety conditions,
Ore removal operation is carried out by going out mine mouth 2.
Wherein, described flexible bag body material is geotextiles, and described slurry is starched for tailing cemented filling material.
The rate of recovery can reach more than 85%.
Claims (3)
1. a kind of method that pattern occupy-place improves ore recovery rate, it is characterised in that comprise the following steps that：
(1) flexible bag body, is laid in Bottom of Stope position, flexible bag body size and dimension is determined as needed；
(2), using pipeline by ground paste filling into flexible bag body, slurry dewatering shaping after formed occupy-place pattern；
(3), explosion falls ore deposit and ventilation, after underground air condition meets related operating regulation to other safety conditions, is gone out
Ore deposit operation.
2. the method that a kind of pattern occupy-place as claimed in claim 1 improves ore recovery rate, it is characterised in that described flexibility
Bag material is geotextiles.
3. the method that a kind of pattern occupy-place as claimed in claim 1 improves ore recovery rate, it is characterised in that described slurry
Starched for tailing cemented filling material.
