Abstract
A technology for increasing the capacity of tailing site for metal mine features that the dam of the said tailing site is further built upward vertically along the axis of upper sub-dam and a hydraulic cyclone is used to discharge the coarse particles outside the damp and stack the fine particles inside the dam. Its advantages include high effect, and high safety.
Description
Affiliated field
The present invention relates to mine tailing and stack the field, particularly a kind of metallic ore mine tailing storehouse increase dilatation technology.
Background technology
Present domestic metallic ore mine tailing storehouse, majority have been in storage volume and the length of service near middle latter stage, continue to produce in order to keep the mine, are all seeking the preferred plan that the mine tailing later stage stores, to solve the storage problem that continues of mine tailing.The approach that solves: the one, build new mine tailing storehouse, the 2nd, transform existing mine tailing storehouse.If build new mine tailing storehouse, there is the problem that investment is many, expropriation of land is difficult, ambient influnence is big, the construction period is long; If dilatation is increased in the original debris storehouse, because the upstream method of building a dam is generally adopted in existing mine tailing storehouse, disperses the discharging mine tailing to build a dam, the sub-dam body that is built up contains multi-level clay parting, the dam seepage line height, structural strength is low, and dam stability is poor, increases dilatation if continue with upper reaches method, difficulty is big, can not build high dam, the dilatation amount is limited, and the unsettled hidden danger of dam body is arranged.
Summary of the invention
The present invention just provides a kind of energy and will have the mine tailing storehouse of building a dam with upper reaches method now and realize significantly increasing and dilatation, and guarantees the stable dilatation technology of building a dam of safety of dam body.
This method is to have the sub-axis of dam in top in the mine tailing storehouse of building a dam with upper reaches method now, for fixed axis 1 is built a dam, adopt hydrocyclone that the mine tailing slurry is carried out the classification of thickness particle, the coarse fraction tailings discharging is outside the dam, made full use of unemployed space outside the dam, fine fraction overflow mine tailing is filled in the storehouse, thereby has realized that the classification of mine tailing slurry builds a dam, dam body raises vertically upward, and dilatation is increased in the original debris storehouse.Fixed axis 1, general selection is positioned at the axis place on the sub-dam of topmost of upper reaches method production status.For guaranteeing that constant voltage gives the ore deposit, long for the axis of dam, adopt the high-density polyethylene pipeline to pressurize to the ore deposit; For the short dam body of the axis of dam, adopt pressure stabilizing well to give the ore deposit from pressing.Adopt hydrocyclone with the mine tailing step emission,, hydrocyclone can be installed in crawler belt and mechanically move and build a dam for the long dam body of the axis of dam; For the short dam body of the axis of dam, available hydrocyclone is mobile trolley used builds a dam.Coarse granule is emitted on and forms mine tailing sand setting accumulation body 2 outside the dam, because physical and mechanical property such as mechanical strength height, the water permeability of coarse granule mine tailing be strong, the dam body that builds up is more stable, and the particulate overflow is discharged into one-tenth mine tailing overflow lithosomic body 3 dam in.The partition size of hydroclone classification is the key factor of technology of building a dam, and determines that the basic principle of partition size boundary value is, guarantee the population equilibrium of tailings discharging amount in the dam, outside the dam, but coarse granule granularity minimum can not be less than 0.05mm outside the dam.Final base of dam place is provided with heap and builds drainage loose rock dam 5 outside the dam, and in order to protect the stable of final dam body toe place, drainage loose rock dam 5 are again that row's diafiltration water body can reduce phreatic line 4.Adopt conventional row to ooze measure in sand setting body domestic demand.The sand setting body is the coarse granule mine tailing outside the dam, and dustproof condition is good, can adopt portable void channels to carry out the moistening dust suppression of large tracts of land beach face, or adopts spray sprinkler dustproof.
Adopt the maintenance method of building a dam, just producing and increase dilatation near the mine tailing storehouse that stores time limit latter stage existing, it is big to have the dilatation amount, and security and stability is good, small investment, and many advantages such as expropriation of land is few, and annual running cost is low have very big economic benefit and remarkable social benefit.
Description of drawings

The specific embodiment
With logical steel plate stone ore industry company mine tailing storehouse is example, and this mine tailing storehouse is existing builds a dam with upper reaches method, has been in storage volume and length of service latter stage at present, continue to produce in order to keep the mine, plan is increased dilatation with the fixed axis method of building a dam with the original debris storehouse, to solve the storage problem that continues of mine tailing.With the sub-dam of the topmost of present production status is fixed axis 1, carrying out layering vertically upward builds a dam, with hydrocyclone the mine tailing slurry is carried out the classification of thickness particle, the coarse fraction tailings discharging piles mine tailing sand setting accumulation body 2 outside the dam, fine fraction overflow mine tailing is filled to storehouse endogenetic sediment body 3, thereby dilatation is increased in the original debris storehouse.Build drainage loose rock dam 5 in the downstream, dam far from fixed axis 210m place, dam, in order to protect the stability at final dam body toe place, drainage loose rock dam 5 are again row's diafiltration dams, can reduce phreatic line 4.Give the ore deposit for guaranteeing constant voltage, because the axis of dam reaches 2000m, adopt high-density polyethylene pipeline pressurized delivered mine tailing, crawler belt is mechanically mobile builds a dam for the 375mm hydrocyclone is installed in diameter, the partition size of hydroclone classification is 0.05mm, greater than 0.05mm is coarse granule, is emitted on and forms mine tailing sand setting accumulation body 2 outside the dam, becomes mine tailing overflow lithosomic body 3 in the dam for the fine grained overflow is discharged into less than 0.05mm.The gradient is 1: 3 outside the dam.In the sand setting body, adopt conventional row to ooze measure.The sand setting body is the coarse granule mine tailing outside the dam, adopts portable void channels to carry out the moistening dust suppression of large tracts of land beach face.
