Abstract
The invention discloses a kind of mining methods of open-stope method afterwards disposable false bottom consolidated fill, belong to underground mining method field, solves the problems, such as traditional Discarded Stope afterwards disposable cementing mining technology vacation bottom construction period and curing time is long, mining efficiency is low.The technical scheme is that：Mineral building back production is carried out, then the complete mineral building of back production is filled；Pillar recovery is carried out, then the complete ore pillar of back production is filled；The foundation retained during mineral building and pillar recovery draw adopting, false bottom is laid with drawing the foundation bottom adopted, then carries out foundation filling.The beneficial effects of the invention are as follows：Due to mineral building back production and the destruction during mine to false bottom can be fallen to avoid traditional handicraft, ensure the intensity for filling false bottom well, provide necessary condition for the top pillar recycling of rear process；The top pillar rate of recovery can be improved；Can to avoid drawn due to first step foundation adopt, the false bottom laying construction period it is long, the problem of back production low efficiency.
Description
Technical field
The invention belongs to underground mining method fields, and in particular to a kind of open-stope method afterwards disposable false bottom consolidated fill
Mining methods.
Background technique
Traditional Discarded Stope afterwards disposable cementing mining technology first carry out foundation draw adopt, false bottom is laid with, then carries out mine
The back production and filling in room and ore pillar, this requires false bottom to bear the later period and falls mine and back production blasting impact, this technique is to filling false bottom
Intensity requirement is high, and false bottom construction period and curing time are long；Drawn due to foundation adopt, false bottom laying construction it is difficult, draw extraction early period
Mine amount is few, and mining efficiency is low.
Summary of the invention
The object of the present invention is to provide a kind of mining methods of open-stope method afterwards disposable false bottom consolidated fill, to solve to pass
It unites Discarded Stope afterwards disposable cementing mining technology vacation bottom construction period and the problem that curing time is long, mining efficiency is low.
The technical scheme is that：A kind of mining methods of open-stope method afterwards disposable false bottom consolidated fill, including with
Lower step：
Step 1: carrying out mineral building back production, then the complete mineral building of back production is filled；
Step 2: carrying out pillar recovery, then the complete ore pillar of back production is filled；
Step 3: the foundation retained during mineral building and pillar recovery draw adopting, vacation is laid with drawing the foundation bottom adopted
Then bottom carries out foundation filling.
As a further improvement of the present invention, in step 3, foundation filling uses all-tailing cemented filling mode.
As a further improvement of the present invention, in step 1, mineral building is filled using all-tailing cemented filling mode.
As a further improvement of the present invention, in step 2, ore pillar is mutually tied using tailing cemented filling with waste fill
The mode of conjunction is filled.
As a further improvement of the present invention, in step 1, mineral building back production is adopted using ladder-like move back from the top down.
As a further improvement of the present invention, in step 2, pillar recovery moves back the side adopted using ladder-like from the top down
Formula.
The present invention changes the construction procedure of traditional Discarded Stope afterwards disposable cementing mining technology, obtains following
Technical effect：
1. due to mineral building back production and the destruction during mine to false bottom can be fallen to avoid traditional handicraft, filling is ensured well
The intensity at false bottom provides necessary condition for the top pillar recycling of rear process；
2. the top pillar rate of recovery can be improved, resource utilization is substantially increased, has played economy of resources；
3. can to avoid drawn due to first step foundation adopt, the false bottom laying construction period it is long, the problem of back production low efficiency, release
Production capacity has apparent economic benefit.
Detailed description of the invention
Fig. 1 is the flow chart of the specific embodiment of the invention.
Specific embodiment
The following examples can further illustrate the present invention, but do not limit the invention in any way.
Embodiment 1：
The Gansu Orebody in Jingtieshan mining industry Co., Ltd middle section capper ore 2760-2820 uses technical solution of the present invention.Birch
The ditch copper mine middle section ore body thickness is big, and ore body interior thickness is all larger than 30m.According to actual production conditions, it is every to divide capper ore
Mono- middle section 60m, every 10m mono- layering, in middle section bottom, every 10m arranges an ore removal river, forms ore removal structure.Construction process
As shown in Figure 1, steps are as follows：
A, mineral building drilling drift is arranged：Nugget divides in such a way that mineral building and ore pillar are alternately arranged, and the middle section is all using vertical
Straight ore body mode arranges mineral building, and drilling drift width and height are 3m；
B, drilling drift vacation bottom is laid with：The reinforced concrete artificial bottom of 0.5m thickness is laid in drilling drift；
C, mineral building deep hole is arranged：Use YGZ-90 borehole drilling machine construction deep hole；
D, mineral building back production：Mineral building using from the top down it is ladder-like move back adopt by the way of carry out back production；
E, mineral building fills：The complete mineral building of back production is filled using all-tailing cemented filling mode.
F, pillar recovery：Ore pillar using from the top down it is ladder-like move back adopt by the way of carry out back production；
G, ore pillar fills：Ore pillar is filled in such a way that tailing cemented filling and waste fill combine；
H, foundation, which is drawn, adopts：The foundation retained during mineral building and pillar recovery draw adopting；
I, foundation vacation bottom is laid with：At the filling vacation bottom for drawing the foundation bottom laying 0.5m thickness adopted, false bottom and mineral building rock drilling lane are false
Bottom is linked to be an entirety.
J, foundation fills：Foundation filling is carried out using all-tailing cemented filling mode.
In the present embodiment, all using such false bottom laying process, false bottom laying implementation result is good in middle section, solves well
It has determined foundation and cap pillar extraction difficulty and the low problem of the rate of extraction.
The present embodiment also solves foundation and draws the problem of adopting, and ore body bottom column stope rate reaches 95% or more, amounts to more recovery articles
About 300,000 tons of Copper Ores of position 2.2% create about 18,000,000 yuan of economic benefit.
The present embodiment middle section bottom vacation bottom forms an entirety, and cap pillar extraction rate is increased to 60% by 40%, recycle ore 4 more
Ten thousand tons, create 2,400,000 yuan of economic benefit.
This invention ensures that filling false bottom intensity, destruction of the back production explosion to false bottom is filled is avoided, later period vacation is reduced
Bottom maintenance cost.
