Description
Technical field
The invention belongs to mining technique fields, are related to a kind of mining methods of slant middle thick orebody.This method is mainly applicable in
In the back production of the slant middle thick orebody of underground gold mining.
Background technology
In slant middle thick orebody exploitation, since ore body horizontal breadth is relatively thick big, in mining process, to ensure to push up
Plate safety, it is necessary to reserved safety pillar, to cause ore losses.If not reserve safety pillar, stope exposure area again compared with
Greatly, security risk is larger, and operation is dangerous.
Invention content
The technical problem to be solved by the invention is to provide a kind of mining methods of slant middle thick orebody, realize to tilting
Middle thickness orebody is safe efficient, low poor damage exploitation.
Technical scheme is as follows：
A kind of mining methods of slant middle thick orebody, it is characterised in that include the following steps：
1）, stope across pitch arrangement, length 55m, ore body width be ore body horizontal breadth, miding level height 40m, height of lift
13.3m, studding width 3m, fore-set thickness 3m；
2）, along orebody trend by stage casing ore body division at stope, stage casing is divided into several segmentations again in vertical direction, is being adopted
Arranged for interval mineral building unit and bar shaped route in；Mineral building unit first carries out back production, after the equal back production of mineral building unit, then carries out
Back production bar shaped route；
3）, in stope when mineral building unit back production, using double mineral building unit parallel operations；When stope inner stripe drift stoping, in advance
Using either route parallel operations, after either route back production, then single route operation is carried out；Either route spacing distance is 24m；
4）, mineral building unit is all using consolidated fill；When bar shaped admission passage filling, in addition to cement plane is using consolidated fill, remainder
Divide using tailing-filled；
5）, in the corresponding stope in stage casing at the end of first floor back production, artificial false bottom is constructed using armored concrete；
6）, stope inner stripe route and the back production of mineral building unit to fore-set lower edge when, all carry out top tight fillings；Cap pillar extraction is adopted
The drift stoping arranged with capwise；
The slanting angle of ore body of the slant middle thick orebody is 45 °~53 °, and ore body horizontal breadth is 15~25m.
Preferably, step 1）In, each two adjacent stope arranges a lower wall ore pass.
Preferably, step 2）In, bar shaped route width 4m, mineral building cell width 10m；One stope arranges 3 routes altogether.
Preferably, step 3）In, double mineral building unit intervals distance of parallel operations is 18m.
Preferably, step 3）In, either route spacing distance is 24m.
Preferably, step 4）In, when mineral building unit fills, cement-sand ratio 1 is used first：16 consolidated fill 2.5m high is remained
Remaining 0.5m high uses cement-sand ratio 1：5 consolidated fill is as cement plane；When bar shaped admission passage filling, packed height 3m is used first
Tailing filling 2.5m high, remaining 0.5m high use cement-sand ratio 1：5 consolidated fill is as cement plane.
Preferably, step 6）In, in stope after mineral building unit back production to fore-set lower edge back production, all using sand-lime
Than 1：
5 consolidated fill carries out top tight filling；When bar shaped drift stoping is to fore-set lower edge, mining height becomes 4m by 3m, bar shaped into
After the back production of road, all using cement-sand ratio 1：5 consolidated fill carries out top tight filling；When cap pillar extraction, using capwise
The specification of arrangement is 3m*3m drift stopings, and using retrusive from both wings to central back production successively, admission passage filling uses cement-sand ratio 1：
5 consolidated fill connects top.
The positive effect of the present invention is：
1, production capacity is big, and mining efficiency is high.Often layering shares 4 mineral building units and 3 routes in stope, and mineral building unit uses
Filling-up method is exploited, and when mineral building unit back production, is all made of double mineral building unit parallel operations, production capacity
Greatly；When bar shaped route initial stage back production, either route parallel operations are all made of, it is efficient.
2, loss late is low, and mining recovery is high.Stope using upward horizontal slice and on to access back-filling method carry out
Back production, ore recovery rate is high, and loss late is low.
3, the rate of dilution is low, and ore removal is high-quality.The mine amount of stope nearly 77% is dug up mine for upward horizontal slice method, ore dilution rate
It is low.
4, operational security is high.Stope is divided into several mineral building units and bar shaped route, stope span is small, exposed area
It is small, it is safe.
5, pack effectiveness is high.On the one hand, when filling, double mineral building units or either route can fill simultaneously, and pack effectiveness is high.
On the other hand, it when mineral building unit fills, is effectively blocked using light section, that is, layered-liaison tunnel or interim ore pillar filling counterfort,
It is efficient to set up barricade.
