Description
Technical field
The utility model relates to a kind of mining mineral buildings, and in particular to dig up mine in one kind to waste fill oper cylinler shallow-hole shrinkage
Mineral building.
Background technique
Be mostly at present traditional oper cylinler shallow hole shrinkage method using mining methods, the small and medium sized gold mine of artificial hoeing ore also compared with
It is common.Since current many small and medium sized gold mine mining sequences are still working from top down, mine pressure is caused to pass to mine deep part
It passs, lower part middle section mine pressure is caused to concentrate.Traditional oper cylinler shallow hole shrinkage method is to utilize original lane upward mining along the pulse, worker
Lower part is through by ore removal and carries out hoeing ore removal, and with constantly transporting for stope ore, top gradually forms goaf, top plate rock
Stone falls off since the effect of mine pressure can be crushed, and worker is in ore removal and pierces into row hoeing, and hoeing distance (range) is by larger
Limitation there are larger security risk, threatens worker's life security if the hoeing below the goaf, at the same goaf without
Backfill is filled by roof caving, will lead to ground settlement, and mineral building low portion ore body permanent loss.
Utility model content
The technical problem to be solved by the utility model is to provide dig up mine in one kind to waste fill oper cylinler shallow-hole shrinkage
Mineral building, reduce barren rock proposes fortune cost, improves mining operations security performance.
The technical solution of the utility model is as follows:
Haulage drift, trend are transported outward with arteries and veins to outside waste fill oper cylinler shallow-hole shrinkage mining mineral building, including arteries and veins in one kind
The perpendicular ore removal in defeated tunnel wears and moves towards parallel along vein transporting drift with the outer haulage drift of arteries and veins, the both ends that ore removal is worn point
It is not communicated with haulage drift outside arteries and veins and along vein transporting drift；It is characterized in that the mining mineral building further includes inclination angle at 40 ° ~ 60 °
Between ore body；Building along the side of vein transporting drift has Inclination body, and the surface slope of Inclination body is consistent with the slanting angle of ore body；Slope
The inclined-plane upper end of body connects with bottom end on the downside of ore body；The inclined-plane lower end of Inclination body and the Inclination body opposite side wall along vein transporting drift
Between there are 80 centimetres -120 centimetres of spacing.
Further: the mining mineral building further includes upper armor rock and lower wall country rock；Between upper armor rock and lower wall country rock
It is provided with studding.
Further: the mining mineral building further includes top pillar, and the top pillar is reserved with small filling well.
The beneficial effects of the utility model are: the freight charges that mention that the utility model not only reduces barren rock are used, stope is reduced
Loss and dilution, realize effective control to mining field pressure, ensure that construction safety, and can be realized and be changed to downlink
Upward mining mode greatly improves exploitation cycle efficieny.The utility model has structure simple simultaneously, construction easy to operate,
It is easy to use, the features such as construction cost is low, it is particularly suitable for the medium and small gold mine of artificial hoeing.
The utility model reserves small filling well on mineral building top, and the useless of quasi- formation is adopted in top middle section after the extraction of mineral building ore body
Stone fills mineral building by filling well, reduces barren rock and proposes fortune.
The utility model uses suspension roof support in stope, along with staying poor value (point column) or concrete pillar pair
Top plate carries out supporting, substantially increases operational security, decreases mining loss and dilution.
Studding is reserved in leading courtyard two sides, supports upper lower burrs country rock, reduces the lateral transport of ground pressure, controls mining field pressure.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the Ι-Ι schematic cross-sectional view of Fig. 1.
Fig. 3 is the utility model along vein transporting drift section structure diagram, this figure is also used to show Inclination body and mine
Body relative positional relationship.
Specific embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples.
Such as Fig. 1 and Fig. 2, the embodiments of the present invention include the outer haulage drift 1 of arteries and veins, trend and arteries and veins 1 phase of outer haulage drift
Vertical ore removal wear 2 and trend with arteries and veins haulage drift 1 is parallel along vein transporting drift 3 outside, ore removal wear 2 both ends respectively with
It the outer haulage drift 1 of arteries and veins and is communicated along vein transporting drift 3.The embodiments of the present invention further include inclination angle between 40 ° ~ 60 °
Ore body 4.
Such as Fig. 3, building along the side of vein transporting drift 3 has Inclination body 9, the surface slope of Inclination body 9 and 4 inclination angle one of ore body
It causes, the inclined-plane upper end of Inclination body 9 connects with 4 downside bottom end of ore body.The inclined-plane lower end of Inclination body 9 with along the oblique of vein transporting drift 3
There are 80 centimetres -120 centimetres of spacing between slopes opposite side wall, the inclined-plane of Inclination body 9 and the Inclination body opposite side wall it
Between space as explosion ore accumulation area.
Still such as Fig. 1 and Fig. 2, the embodiments of the present invention further include studding 6, put column or concrete column 7, reserve
Small filling well 8.Upper lower burrs country rock is supported by studding 6, reduces the lateral transport of ground pressure, controls mining field pressure.It is used in stope
Suspension roof support, while reserved poor value (point column) or concrete pillar 9 carry out supporting to top plate, improve operational security,
Reduce mining loss and dilution.
Upward mining can be realized by the utility model, and the backfill of Upward mining barren rock is that top barren rock is pre- in top pillar 5
It stays small filling well 10 to backfill dead zone, reduces barren rock and propose fortune, effectively control ground pressure, accelerate upper part work work cycle, improve
Mine capacity obtains good economic benefit.
Arrangement stope is moved towards along ore body 4,40 meters of length of stope or so, the haulage drift 1 outside the former parallel arrangement of lane along the pulse arteries and veins,
2 are worn every 5 meters of arrangements, one ore removal, forms courtyard in advance in stope two sides, was tunneled after adopting quasi- formed along former lane bottom along the pulse
The barren rock formed in journey builds Inclination body 9, slips ore to explosion ore accumulation area certainly along the inclined-plane of Inclination body 9.Mineral building exploitation
Middle and upper part stays 3 meters of protective layers as top pillar 5, while reserved 3 ~ 6 small filling 8, and stope, which goes out net upper back middle section, to be adopted quasi- engineering and open
Begin to construct, by 8 pairs of lower parts of small filling, empty mineral building fills the barren rock of formation.
The utility model explosion ore accumulation area belongs to the safe and effective area of artificial hoeing, and worker, which is in ore removal and wears in 2, to carry out
Hoeing operation, not only ensure that operation safety, it is thus also avoided that the permanent loss of ore.According to standard mineral building length 40m, ore removal product
Position 2.5g/t, permanent loss area volume are 2 × 40m of (1m × 1.5m) ÷=30m3, and ore density is 2.75t/m3, i.e. a mine
Room can reduce loss 2.75 × 30=82.5t of mine amount, and Medium and smaller mines are calculated according to annual 70 mineral buildings of exploitation, saved increasing
Mine 82.5 × 70=5775t of amount, 270 yuan/g of price of gold, will increase by 1,560,000 yuan of profit for mine in 1 year；It is piled up simultaneously using barren rock
Reduce barren rock proposes fortune 4620 tanks (30 × 1.65 ÷ 0.75 × 70=4620), and saving mentions nearly 140,000 yuan of fortune fund；1 year altogether
Increase by 1,700,000 yuan of profit, benefit is evident.
