In Fig. 2, Reference numeral 5 shows the clay grounting layer.Reference numeral 6 shows ore body.Reference numeral 7 shows without mine belt.
The utility model provides a kind of ion adsorption type re original place to soak the ore deposit mother liquor recovery system, it is according to distance between ore deposit soil permeability, local phreatic table, ore body bottom and the basement rock 8 and consider that the factors such as dynamic change of each position water ratio in the nugget production process select suitable position on massif surface (hill-side or the foot of the hill), determines the position that the pod apertures of rare earth mother solution recycling engineering surface is constructed; According to the position of choosing, implement the artificial steep bank 3 of 30-100 centimetre, for using hydrodrill or water blast gun, next step provides the construction plane.
Position according to the pod apertures construction of the Engineering Control face of determining, on the construction working face of finishing, interval 15-150 centimetre is by pod apertures direction and the inclination angle of design, use hydrodrill or water blast gun (hour can use more convenient at massif) construction to be used for the pod apertures that leach liquor reclaims, the final liquid collection engineering surface that moves towards the pod apertures that is parallel to each other 1 composition of direction along massif that forms, and the final liquid collection engineering surface that is formed by all pod apertures 1 that forms, compared with the space curved surface that the ore body bottom consists of by the liquid collection engineering surface that all pod apertures form, be in same position or omit lower position.
Described pod apertures 1 is moved towards direction along massif, does not allow such as condition, and the pod apertures 1 of vertical massif trend or other direction can be set.
When the inclination angle of ore body bottom is larger, two-layer or multilayer can be set along the pod apertures 1 of massif trend (when condition does not possess vertically massif move towards or other direction), but finally also be to form the liquid collection engineering surface that is formed by all pod apertures 1, the space curved surface that the space curved surface that itself and ore body bottom consist of is in same position or consists of a little less than the ore body bottom.
Can implement two row's pod apertures 1 at same position according to practical situation; The inclination angle of pod apertures 1 meets the inclination angle that forms the ore body bottom of section along pod apertures ore body that direction is cut; The pod apertures relative position is basically identical with the ore body bottom shape of the ore body profile of vertical pod apertures direction.
Pod apertures is not carried out the antiseepage processing generally speaking, processes but can carry out antiseepage to it yet.For easy construction reaches the direction of controlling better pod apertures, can implement along the pod apertures engineering position of determining artificial steep bank 4 (being generally the 30-100 centimetre).
Mother liquor is collected by implementing the open drain in bottom in pod apertures 1, and namely intercepting gutter 2.Particularly, export to collect leaching liquid by connecting each pod apertures in construction open drain, pod apertures outlet bottom, in position by pipeline mother liquor is imported the transfer pond; That is to say, according to the pod apertures position of having finished, (be close to the pod apertures exit) in its underpart and implement the open drain, be used for collecting the rare earth leaching liquid that is flowed out by pod apertures; Least significant end in the open drain, with pvc pipe or other pipelines with rare earth leaching liquid (mother liquor) drainage of collecting to mother liquor transfer pond; For preventing that the non-mother liquid coming in massif surface (such as rainwater etc.) from importing mother liquor and collecting the open drain, implement the open drain in the appropriate location, top of pod apertures, collect the massif non-mother liquid coming in surface and discharge by pvc pipe or other pipelines.
Implement open drain (keeping away ditch 4) on pod apertures top, i.e. ditch 2 is collected to prevent non-mother liquid coming (such as natural precipitation etc.) to import mother liquor in waterways.Particularly, adopt the open drain mode to set up massif in pod apertures outlet appropriate location, top and keep away water system, prevent that natural precipitation from importing rare earth mother solution; Keep away ditch 4 and keep away the ditch escape route and be communicated with; And intercepting gutter 2 is collected pipeline connection with intercepting gutter.
In the technical solution of the utility model, if the inclination angle of ore body bottom is large or the ore body changes in bottom is larger, have any problem by above scheme implementation and maybe may cause the wasting of resources, then can implement to different zones the pod apertures of different layers position, its ultimate aim is to form the liquid collection engineering surface that is comprised of all pod apertures, and the space curved surface that itself and ore body bottom consist of is in same position or omits lower position.
Appropriate location in the technical solution of the utility model refers to according to distance between ore deposit soil permeability, local phreatic table, ore body bottom and the basement rock and considers that the combined factors such as dynamic change of each position water ratio in the nugget production process are definite, the one, the adaptability of definite this technique, the 2nd, in the situation that can use this technique, determine pod apertures position, pod apertures direction and pod apertures inclination angle according to above combined factors.
According to the utility model, can further reduce the ion adsorption type re original place and soak the ore deposit in the artificial casting amount of receiving in the process of the false end of liquid of construction, reduce the hidden danger of soil erosion; Greatly shorten the engineering time that the ore deposit liquid process is soaked in the original place, increased the security of construction; Removed in the past that liquid process effectively reduces production cost to the demand of the support materials such as trees and other subsidiary material, indirect protection ecotope.
For the position of the pod apertures construction of determining rare earth mother solution recycling engineering surface, need by distance size between ore deposit soil (the ore deposit soil that refers to the engineering construction part) perviousness, local phreatic table position, ore body bottom and the basement rock and in process of production the variation of the ore body water ratio between ore body bottom and the basement rock (or phreatic table) determine.
If the ore deposit soil permeability is good, then the Engineering Control face is positioned as close to local phreatic table or basement rock, but also need to consider the lower water ratio that has improved part (namely without mine belt) between phreatic table and phreatic table (or basement rock) and the ore body bottom that oozes because of liquid before the ore deposit, this is conversely again so that ore deposit soil permeability variation.Press close to as far as possible bottom the ore body and the situation of poor permeability is next, its purpose is in order to improve mother liquid concentration, to reduce reservoir quantity.For example: the ore body good penetrability, and the distance between phreatic table or basement rock and the ore body bottom is 3 meters (namely without mine belts), so, before not considering the ore deposit, ooze under the liquid to below the Engineering Control face perviousness being changed in the situation of (water ratio improves perviousness and weakens), should press close to the construction of phreatic table or basement rock, if but the lower milliosmolarity of liquid (can calculate) has improved 1 meter of phreatic table (or make it perviousness become very poor) before (or calculate) ore deposit, then the Engineering Control face is than 1 meter of phreatic table or basement rock raising.
In some situation, basement rock is darker, but phreatic table is higher and phreatic table and ore body distance from bottom are little, so, do not consider the impact of oozing under the liquid before the ore deposit, do not consider perviousness and infiltrative variation, to press close to the phreatic table construction as main (if any the construction possibility, comparable phreatic table is slightly low).
In some situation, phreatic table is lower, but basement rock is little from the ore body distance from bottom, so, does not consider the impact of oozing under the liquid before the ore deposit, does not consider perviousness and infiltrative variation, to press close to the basement rock construction.
Such as good penetrability, do not considering that perviousness and phreatic table change, then press close to phreatic table or press close to the basement rock construction;
The size of the distance between ore body bottom and the basement rock (or phreatic table), large such as distance, and good penetrability, then this technique is inapplicable, large such as distance, but poor permeability, then to press close to the construction of ore body bottom, little such as distance, good penetrability is then pressed close to the construction of phreatic table or basement rock, and is little such as distance, it is also poor to permeate, and presses close to equally the construction of phreatic table or basement rock; This factor is determined except construction location, has also been implied the adaptability of technique.
The dynamic change of each position water ratio refers to ooze under the liquid before the ore deposit impact on perviousness, phreatic table etc. in the nugget production process, can further improve the technique use range, such as: the distance between ore body bottom and the basement rock (or phreatic table) is larger, and its good penetrability, but before the ore deposit under the liquid milliosmolarity can improve 2 meters of phreatic tables or make 2 meters on basement rock top become impermeable bed (or infiltration poor), then can reach in the situation of optimum efficiency improving 2 meters constructions, then improve 2 meters and implement this technique; As permeate poorly, then press close to ore body bottom and suitably encrypt pod apertures and implement this technique and can reach best effect.
Generally speaking, determine that the construction location of rare earth mother solution recycling engineering face need to be considered above all respects, need to be according to mutual relationship between all respects, the factors such as Technological Economy during in conjunction with exploitation are determined construction location jointly.
In one embodiment, the distance between the pod apertures is 15-30cm.In another embodiment, the distance between the pod apertures is 15-150cm.Between perviousness and the pod apertures distance determine be related, poor permeability then pod apertures distance is little, the good penetrability distance can be relaxed.On the other hand, in the situation of same pod apertures distance, in order to guarantee construction quality, adjacent pod apertures can be constructed into staggered up and down form.
