The periphery of the box is provided with two rows of windows used for observation; an upper row and a lower row of monitoring instruments are arranged on the box in a coiled manner; a hydraulic support device is arranged below the box in a coiled manner; the top end of the box is provided with an interface which can be connected with distributed liquid of spray atomization, distributed liquid of a dual-rectangular-shaped pipe and distributed liquid of a pre-embedded pipe and is further provided with a pressure-indicating and flow-controlling-and-metering equipment mounting port which is fixed on a reinforced ribbed plate of the box; the box is embedded into a base; the upper end of the base is provided with a collection plate; and the collection plate may be divided into square grids or concentric circles, each grid has an independent water outlet, and the upper end of the outlet is provided with a filter layer. The multifunctional testing apparatus can be used for testing of solution seepage distribution of the steeply-inclined loose fragmented medium and ore leaching effect under the condition of different inclination angles; and a method for determining influence of a plurality of parameters like an inclination angle and a liquid distribution method can be provided for leaching treatment of solid waste and soil contaminated by harmful metals.
Description
Technical field
The present invention relates to the device that the distribution of a kind of fluid flow for high-dipping loose crushing medium is tested with distribution and the ore seepage flow leaching effect of solution under the device, particularly different angle of leaching test.
Background technology
Stope leaching exploitation be melt adopt, smelting in one novel recovery method, compared with exploiting with routine, decrease the operations such as ore removal, roof control, Yun Kuang, fragmentation and Separation of Solid and Liquid, have the advantages that technique is simple, cost is low, efficiency is high.This recovery method is suitable for ore body that is vertical or high-dipping, and ore is Stacking by blasting in advance, with diverse ways, leachant is piled with loose crushing ore deposit afterwards and contacts, leaching valuable metal.The leaching of low-grade uranium, gold, copper, silver etc. can be widely used in.
[underground heap is actually loose crushing medium, and other porous medium is as soil, crack rock etc. relatively, and one is that particle grading distribution is extremely uneven, and two is that grain diameter is comparatively large, and three is there is not connection between particle or only there is weak connection.[underground piles the complicacy of specific boundary condition, structural form, and ore deposit stack height is large in addition, and ore deposit is piled and also be there is wall effect between not quick-fried country rock around, can affect the homogeneity of cloth liquid, and then affect leaching effect.In recent years, stope leaching achieves breakthrough progress in technical research and application, but still has many technical barriers urgently to be resolved hurrily, for the inclined orebody accounting for significant proportion, topmost influence factor how to make leaching agent be evenly distributed at ore deposit heap, efficiently leaches; Next is the granularity ensureing to build heap, thus limits the expansion of Situ Leaching technology and range of application to a certain extent.For this reason, exploitation is a kind of multi-functional for high-dipping loose crushing medium test unit, carrying out the seepage flow of high-dipping loose crushing medium solution and leach research, to improving stope leaching and solid waste, the research of harmful metal pollution soil extract technology, being of great immediate significance.

Experimental provision as above, wherein casing is formed by PVC board welding assembly, the thickness of plate is between 10-15mm, use 5# angle steel reinforced outside plate, the distribution of angle steel should ensure casing uniform force, is convenient to again the setting of other accessories as monitoring mouth, support bar, by rubber ring seal between plate and angle steel, and fixed by stainless steel screw, be provided with in the surrounding of casing the form that two rows are used for observing, upper dish casing is provided with the interface that 2 are installed pH/ORP sensors.First make through mechanical grinding rough inside PVC board, it is made with epoxy resin more rough, thickness 3-5mm.
Experimental provision as above, wherein gathering-device is welded by PVC board, collecting board is divided into grid or concentric circles two kinds of shapes, every lattice have independently water delivering orifice, freeing port aperture 10mm, and outlet is provided with one deck 30 order plastic filtering net near upper end, screen pack is covered with silica sand, quartz sand layer thickness 40mm, water delivering orifice is by Valve controlling, and collecting board is placed on base.
Experimental provision as above, wherein base is formed by angle steel, steel-pipe welding, be separated into the netted of 200 × 200mm, four pin are provided with the structure of location casing, and bearing is concave structure, and collecting board is bumped in concave structure, the upper surface of surrounding is concordant with the upper surface of collecting board, 6 legs are by 50mm steel-pipe welding, and leg lower end is welded with 10mm circular steel backing plate, diameter 100mm.
Experimental provision as above, wherein supporting construction is by hinge, support bar and elongated lifting jack composition, lifting jack tonnage 5t, stroke 100mm.Its advantage is the length that can adjust support bar when changing the casing of different angles in time, ensures that casing is stablized.
Experimental provision as above, the interface wherein installing monitoring instrument adopts double-jacket tube, and outer tube is drilled with the aperture of 5mm by casing center-side, distribute in plum blossom-shaped, inner sleeve cuts open as semicircle, and front end is closed, rubber stopper seal is relied between inside and outside two-layer sleeve pipe, sleeve pipe is rotatable, when needs are monitored time, and its opening upwards, collect solution, be convenient to monitor fully contact with solution, when not needing monitoring, opening points to side.
