Description
Technical field
The present invention relates to a kind of filling mining method using concrete component assembling foundation, metal mine underground mining necks
Domain.
Background technique
In recent years, the application with scientific and technological progress in mineral engineering, bargh and scientific research and design unit in China
Under joint efforts, the development of Cut-and-fill Mining Technology is ripe day by day.At this stage, the method for mining by the way of filling is because of its low rate of dilution, high time
Adopt rate, economize on resources, operation safety the advantages that, be widely used in metal mine, in addition, the method for mining by the way of filling control press,
Prevent rock burst etc. from also functioning to huge effect, so Cut-and-fill Mining Technology will become the mainstream in mine resources exploitation field
Development trend.
Now, the construction of sill pillar of mining methods is broadly divided into three kinds: funneling foundation, moat ditch formula foundation and hybrid bottom
Column.Funneling foundation is damaged less, is accounted for foundation ore sum-rate very little by disturbance mine amount, thus stability is relatively high,
For the ore foundation in domestic mine by mine tunnel, most of is all using funneling foundation.The advantages of moat ditch formula foundation is can letter
Change bottom structure, thus the preparation speed of foundation can be accelerated, reduces ore losses when back production foundation.But on the whole, bottom
Column operation complex process is changeable, and cutting quantity is big, and kiloton adopts Qie Bigao, and low efficiency, maintenance capacity is big and not convenient for safeguarding, cause mining at
This is high.The preparation speed in foundation tunnel is slow, and the preparatory period is long, and the amount of labour is big, and account for the total amount of labour of back production nugget 30% is left
The right side, and worker's plenty of time is used to ward off leakage, causes to adopt quasi- overlong time, and labor intensity of workers increases, and seriously restricts mining
Efficiency.Further, since the complex-shaped multiplicity of foundation, and in blast working, the stress of primary rock and the entirety for destroying ore are steady
It is qualitative, so that the whole viscosity of ore itself reduces, it is easy to produce the danger of inbreak.In the actual production process, can make to dig
Funnel out is second-rate, not only reduces ore removal ability, also reduces the quality of ore second-time breakage, dislikes working condition
Change, or even injures the safety of miner.
During underground mining at this stage, foundation ore is as second working resource, because of its complex geologic conditions,
It is especially influenced by geological environment around, back production condition not can determine that factor is more by larger limitation, and top and the bottom are adopted
The leading back production in field destroys the integrality of foundation ore body, and foundation is made to be easier fall damage, brings very big be stranded to bottom column stope
It is difficult.So foundation generally as permanent loss without back production, greatly reduce the rate of extraction, do not meet economizing type exploitation design reason
It reads.In recent years, many mines replace funnel with moat ditch, substantially increase back production efficiency with the mode of trackless equipment haulage ore,
But the problems such as still no solution foundation ore recovery rate is low, and safety is poor.The safe and effective back production of foundation, which becomes, urgently to be solved
Problem certainly.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of filling mining method using concrete component assembling foundation,
It is easy for construction, ore recovery rate is effectively improved, it is highly-safe.
The present invention is realized using following scheme: a kind of filling mining method using concrete component assembling foundation, special
Sign is: the following steps are included:
(1) nugget arrange: ore body is divided into the stage in the height direction, along orebody trend by divided stages be nugget,
Nugget length 60m, nugget width are orebody thickness, arrange manway shaft, ore pass every 60m along the tunnel Chuan Mai；
(2) quasi- cutting is adopted: along orebody trend arrangement stage haulage drift, perpendicular to orebody trend in the lower wall arteries and veins of ore body
It undercuts comprehensively, the height that undercuts is 5m, assembles foundation, the foundation of assembling using concrete component in the space that nugget bottom drags down
Height is 4m, and there are 1m above foundation falls the compensation space of mine as deep hole, and there are component assembling tunnel, component groups among foundation
Dress tunnel is communicated with the artificial dress mine route of two sides；
(3) back production and ventilation: a drilling drift is tunneled along orebody trend on ore body top, drilling drift is distinguished every 5m
To two sides thurl, beats vertical long hole downwards with drill jumbo and carry out segmentation short-delay blasting；Along orebody trend retrusive
Production ore, until mineral building back production finishes；The ore that explosion is got off is transported to horizontal ore by manually filling mine route by scraper
Drop shaft is transported by discharging tunnel；After explosion i.e. be aerated, it is fresh it is distinguished and admirable by exploiting field air inlet courtyard enter connection roadway, then
Component assembling tunnel and stope is entered by connection roadway, behind cleaning face, waste air enters ventilation shaft and filling well again through return air
Earth's surface is discharged in well；
(4) filling operation: carrying out stope filling after ore back production, using all-tailing cemented filling, filling slurry
Concentration is controlled 60% ~ 70%.
Further, in step (4), the detailed process of filling are as follows: (a) dehydration in stope: the concrete component of foundation is formed
In be embedded with steel pipe with holes as dehydration equipment；(b) it stope Seal treatment: is slipped by ore of the casting concrete component to stope
Well, manway shaft, component assembling tunnel and stope both sides are closed；(c) stope filling: use cement-sand ratio for the full tail of 1:5
Sand consolidated fill, filling slurry pass through filling well one-time filling stope.
Compared with prior art, the invention has the following advantages: the present invention manually component assemble foundation, structure letter
It is single, it is easy for construction, flexible arrangement construction of sill pillar can be needed according to stope, it is simple adopt quasi- cutting technique, it is possible to reduce ore
Loss improves the rate of extraction, does not have to second working foundation, safety is good, the existing foundation complex process of effective solution, back production efficiency
It is low, the outstanding problems such as safety difference.
To make the objectives, technical solutions, and advantages of the present invention more comprehensible, specific embodiment and phase will be passed through below
Attached drawing is closed, invention is further described in detail.
