Description
Technical field
The invention belongs to mill tailings storehouse field, more particularly to a kind of pipe network system for administering Tailings Dam frozen soil and its
Construction method.
Background technology
Frozen soil is referred to below zero degrees celsius, and the various rocks and soil containing ice.Frozen soil is related to the physics of soil, water, ice
Property is coupled, while being related to the heat conduction problem of air, frozen soil layer and bottom Rock And Soil.
The frozen soil phenomenon of Tailings Dam is inherently consistent with the frozen soil phenomenon of nature, has and freezes and melted
Journey, can all be divided into permanent frozen soil and frost zone, but there is also significant diversity：1) ground of nature is substantially solid
Fixed, and tailing dam beach face is constantly to rise, ice face rises to be carried out with beach face rising synchronous, and it is low that its rate of climb has
In frost zone depth, what is had exceeds well over frost zone depth；2) when Tailings Slurry is discharged on beach face, 4 DEG C of own temperature
~10 DEG C, in saturation, in beach face flowing time stage deposition, the bleeding in infiltration, into after frost zone further in subglacial
Deposition.
In general, seasonal frozen ground layer is interior then under the conditions of uncovered after the spring is warm all to melt in addition to Qinghai-Tibet Platean.
For Tailings Dam, uncovered condition is difficult to keep, because Tailings Dam general winter takes ore drawing under ice sheet, piles up mine tailing shape
Into frozen soil, and after spring warm defrosting, recover to disperse ore drawing before dam.Dispersion ore drawing is carried out before frozen soil layer does not melt completely, quite
In having added mine tailing coating on the frozen soil layer for not yet melting.At this moment general temperature is relatively low, and the low temperature of capped frozen soil layer is difficult
To conduct, original frozen state can only be kept, as tailings discharging continues to rise, increasing the buried depth of frozen soil layer becomes deep
Layer frost zone.In plane along certain direction continuous distribution, vertical direction receives seasonal effect for Disjunct distribution to deep frozen layer, embedding depth
Number of degrees rice is to tens of rice.Can be continuous along flowage line direction, or it is discontinuous.In the width in vertical flowage line direction
Degree, each Tailings Dam can different, with mine tailing granularity, to deposit the factor such as beach longitudinal gradient, saturation water level and gradient relevant.Deep layer
Frost zone is affected less by ambient temperature, and mine tailing is covered causes low temperature to be difficult to transfer out, so typically all maintaining freezing state.
Deep frozen layer is hard, and soil particle is cementing by ice sheet, but heat is melted.
The main harm of Tailings Dam deep layer frozen soil layer shows the following aspects：
1) tailing dam saturation line is caused to raise：The Tailings Dam higher for saturation, if saturation near initial stage dam crest
Higher or effusion, it is possible to create hard frozen soil.Because hard frozen soil bad hydraulic permeability is be close to waterproof, fill dam seepage water is hard
Frozen soil is intercepted, it is impossible to is continued extravasation formation and is choked water, causes dam slope saturation to rise.Deep frozen layer is located in fill dam, quite
In fluid-tight water barrier, when the seepage water that its top is come flow to this layer, intercepted by this frost zone, it is impossible to ooze under continuation, quilt
Compel to switch to horizontal seepage flow, until oozing under this frost zone downstream lateral edges ability, this is just greatly improved fill dam saturation water
Position.
2) dewatering effect of water seepage drainage facility is reduced：Due to deep frozen layer impermeable role, whether vertical row is oozed or level
Row is oozed, or early stage it is pre-buried or after the row that sets up ooze, all because being acted on by horizontal freezing layer water proof, be hardly formed vertical pumping
Funnel, is greatly lowered the dewatering effect of water seepage drainage facility.
3) stability of dam body is reduced：Saturation buried depth is the key factor for affecting tailing dam dam slide stabilization, and saturation is carried
The high stability for necessarily reducing dam body side slope.When especially deep frozen layer is near dam slope, dam slope can be caused to seep water for a long time natural pond
Poolization, frozen soil thaws and is likely to occur floating ice even Local Sliding.If dam seepage line dam crest effusion in the early stage, it is possible to create hard
Hard frozen soil, the spring warms up and comes interim, and the loose frozen soil in top melts fast, and ice crystal bleed causes top to carry out the water yield greatly, and now initial stage dam crest
Hard frozen soil melts slow and substantially impervious water, causes frozen soil upper pond level to rise fast, infiltration gradient increase, easily causes stream soil etc.
Seepage erosion, even results in dam body unstability.With mine tailing pile up absolute altitude rising, in storehouse deep frozen layer long-term high pressure,
Under heat effect, it is possible that melting, the frost zone intensity of thawing drastically reduces, away from free face thickness it is less under the conditions of can
Therefore dam body unstability can be caused.
4) impact of the frozen soil to Tailings Dam structures：The soil body, because water congeals into ice in soil, and is around migrated when freezing
The water for coming freezes to produce volumetric expansion, and body frost heaving can make drain pipe protuberance, disconnect even crack, and drain pipe both sides frost heave is uneven
Pipeline bending, deflection can be made when even.Body frost heaving is uneven to be caused Overflow Tower deflection or even collapses.Frozen soil intensity when melting
Reduce, big sedimentation and deformation can be produced, if structure base is in frozen soil layer, structures produce sedimentation and deformation, produce uneven
Even sedimentation can cause structures to incline, crack is even destroyed.
For the main harm of above Tailings Dam deep layer frozen soil layer, existing general counter-measure mainly includes：
1) ice period low water level operation：In order to mitigate the harm of frozen soil, Tailings Dam should carry out low water level operation before ice period.
Low water level operation has three big benefits：One is that dam seepage line water level can be made low, and loose frozen soil scope is big during frost；Two is hard jelly
Soil is away from dam slope, little to dam body seepage flow and stabilizing influence if forming deep frozen layer；Three is the storehouse for expanding winter subglacial ore drawing
Hold.
2) ice period take subglacial ore drawing：To prevent from depositing beach formation ore pulp Freezing block and floating ice layer, winter extremely frigid zones
Tailings Dam is using ore drawing and subglacial ore drawing under water.Subglacial ore drawing should also be as carrying out many mouthfuls of ore drawings, in case mine tailing is piled with stifled at one
The plug mouth of pipe, if necessary should also be in frost top layer punching ore drawing.
3) frozen soil just recovers ore drawing before dam after melting：Mine tailing covering is discharged to prevent frozen soil layer to be particularly hard frost zone
Deep frozen layer is formed, when warm frozen soil of annual spring starts to melt, does not rush to recover ore drawing before dam, should treat that hard frozen soil all melts
Recover ore drawing before dam after change again.The short Tailings Dam in deposition beach more should be thus, in case deep layer frozen soil layer harm.
Although after being processed by above-mentioned measure, can to a certain extent reduce Frozen soil problems, also necessarily affect
Mining production.Especially for the formation for preventing deep layer frozen soil layer, the measure of ore drawing before could recovering dam after frozen soil melts, so
The mine significantly underproduction is will result directly in, or even is stopped production.The area longer for ice period, frozen soil layer is relatively thick, the thawing time
It is corresponding longer, the underproduction or the off-time it is long, economic loss is often difficult to bear.
