Description
【Technical field】
The present invention relates to exploitation of mineral resources technical fields, and in particular to a kind of production practice of copper mine.
【Background technology】
Copper is one of the earliest copper alloy that the mankind have found, its matter is soft, rich in ductility, has good heat conduction and conduction
Performance, tool and daily necessities can be processed by slightly beaing.The development of human society depends on substance, and mineral resources are then
One of these important substance bases.Currently, 95% or more the energy, 80% or more the raw material of industry and 70% or more agricultural it is raw
Production data both is from mineral resources.Mineral resources come from mine mostly, and have an opencast mining of building stone type mine as China
The part in all kinds of mines can account for total mine 60% or so for the number of mine, therefore its comprehensive utilization of resources is realized
Degree, to China's mine resources comprehensive utilization overall development play very important effect, in building mine field how
Mine resources are comprehensively utilized, mine environment is protected, build Green Mine, promotes green mining to do more and benefits our pursuits, promote mine
The lasting health coordinated development for producing development of resources comprehensive utilization and ecological environment has important directive significance.
Since early 1980s, China's mining activities order is more chaotic, and a large amount of people adopt so that in natural ore body
There is a goaf there are many, and the mining methods of advanced winning equipment and science could not be used since the people adopt so that natural mine
Internal goaf shape, structure not science, and its distribution is irregular, causes goaf stability poor, and personnel can not be direct
Into goaf operation, prodigious difficulty is caused to the safe and efficient back production of ore body, and cause the damage of ore in exploitation process
Mistake rate and the excessively high problem of the rate of dilution.
【Invention content】
In view of this, the purpose of the present invention is to provide a kind of production practice of copper mine, production practice of the invention is to mine
The controlling extent of body is high, can effectively improve copper mine rate of recovery when mining, reduces copper mine loss late and the copper mine rate of dilution, improves
The utilization rate of mineral resources provides resource guarantee for Sustainable Development of Mine, has good use value and application prospect.
In order to solve the above-mentioned technical problem, present invention employs the following technical solutions：
A kind of production practice of copper mine, includes the following steps：
(1) it prospects：Perpendicular to the exploration row of the direction arrangement interval certain distance of ore body principal length on predetermined absolute altitude
Line tunnels prospecting drift, until puncturing entire ore body along exploration line；
(2) it digs up mine：It is dug up mine by the way of big cross section driving, while mining, vacant mining area will have been exploited
Four walls are built into the annular solid in four faces up and down with reinforced concrete structure, and one section of annular is just constructed per exploiting one section forward
Body, adjacent two annular solid are built into integral structure, and the vertical beam of build support is spaced between the inner wall up and down of annular solid, right
The internal face of annular solid carries out Anti-steam-leakage, leakproof water process, and the mine hole of production or life is formed after the completion of coal mining；
(3) back production：On predetermined absolute altitude described in step (1), ore body is divided into two ore beds and carries out back production respectively, along mine
Phosphor bodies trend caunches to ore body main body using shallow hole shrinkage method；
(4) desliming：One section of graded desliming, the sand setting of one section of classification are carried out to the ore pulp collected using hydrocyclone
The agitator being sent into before flotation, the overflow of one section of classification are sent into dense bucket and carry out two sections of graded deslimings, and the sand setting of two sections of classifications is sent
Enter the agitator, tail is lost in the overflow of two sections of classifications.
In the present invention, further, the back production in the step (3) is to carry out back production respectively to two ore bed of ore body, is first adopted
Upper layer Hou Cai lower layers, back production lower layer ore bed after after upper layer mine balkstone avalanche and stablizing.
In the present invention, further, the interlayer between two kinds of mining methods stope of the upper and lower layer should ensure that 4-6m's
Thickness.
In the present invention, further, Anti-steam-leakage, leakproof water process are carried out to the internal face of annular solid in the step (2)
Concrete mode be：The internal face of annular solid is handled by way of injection or slip casting or surface plastic spraying.
In the present invention, further, back production step releases ore using rock drill rock drilling, explosion in the step (3)
One third is left workbench of the ore as next back production rock drilling.
In the present invention, further, the outside in minery is provided with the logical of fresh air conveying to minery
Wind facility.
It is further, described that gas boring and surveying and warning device are provided in minery in the present invention.
In conclusion by adopting the above-described technical solution, the beneficial effects of the invention are as follows：
1. the production practice of the copper mine of the present invention is on predetermined absolute altitude perpendicular to the direction prospecting drift of ore body principal length
Up to puncturing entire ore body, under the situation that mine locating wears that arteries and veins discloses ore body and country rock distribution, cutting work is adopted by being carried out to ore body,
Back production of caunching is carried out to ore body main body using shallow hole shrinkage method, it is high to the controlling extent of ore body, mine when mining can be effectively improved
The stone rate of recovery reduces ore loss ratio and ore dilution rate, improves the utilization rate of mineral resources, provided for Sustainable Development of Mine
Resource guarantee.The present invention makees the cutting of adopting that ore body carries out, and stability is good, safe and reliable, can effectively improve mining efficiency.
2. the present invention greatly reduces the danger coefficient of cutter's operation, and the overall cost dug up mine is low, is suitble to various
The exploitation of mineral.
3. the present invention carries out back production of caunching using shallow hole shrinkage method to ore body main body, simple in structure, management facilitates, adopts quasi- work
Journey amount is small, has good use value and application prospect.
4. the present invention is directed to the characteristics of copper mine, that is, is digging up mine in each flow of ore dressing or operation, easy ting produce particulate
With the crushing sludge excessively of micro-size fraction, directly affect preparation equipment sorts efficiency, reduces the copper ore dressing rate of recovery and money
Source utilization rate, therefore the step of carrying out desliming after mining carry out one section of graded desliming using hydrocyclone, and dense bucket carries out
Two sections of graded deslimings are adjusted ore particle degree using the difference of hydrocyclone and dense bucket grading power, especially pair
The removal of fine particles mineral reduces fine particles mineral to the greatest extent in the case where ensureing that coarse particles mineral loss is reduced
Content makes ore pulp reach the desired particle size needed for flotation.
