Abstract
The utility model discloses a tailings drainage engineering structure which comprises a tailings pond encircled by tailings dams; a smooth clay blanket layer is arranged in the tailings pond, cancellate filtering ditches, which are mutually communicated, are respectively dug in the tailings pond, a dust and sand bedding layer is laid at the bottom of each filtering ditch, an impermeable membrane layer is laid on the dust and sand bedding layer, and a layer of coarse sand layer is laid on the impermeable membrane layer; perforated pipes, which are mutually communicated, are respectively laid on the coarse sand layer of each filtering ditch, a filter screen is respectively bound outside each perforated pipe, a geotextile is respectively laid on the perforated pipe, and a plurality of layers of coarse sand and pebbles are respectively laid on the geotextile in sequence; and then the geotextile is covered, a plurality of layers of pebble layers are laid on the geotextile, and a layer of coarse sand layer is laid on the top surface. The tailings drainage engineering structure has simple structure, is convenient for operation, and serves the functions of natural purification and cyclic utilization to the drainage of the tailings pond.
Description
Technical field
The tailings storehouse drainage that the utility model relates in the ore dressing is handled, and specifically is a kind of tailings drainage works structure.
Background technology
Traditional tailings processing method is to take the in line technology of mine tailing (concentration is about 20%), sets up the tailings storehouse.Because a large amount of mine tailings (wet) are piled up ground, along with the accumulation of dam body is more and more higher, is prone to outside the dam or dam facing seepage flow, gushes pipe, flow native phenomenon, not only environment has been caused heavy damage, and the bigger potential safety hazard of existence.
The utility model content
The utility model provides a kind of tailings drainage works structure, has simple in structurely, easy to operate, and self-purification, recycling effect are played in the draining of tailings storehouse.
The technical solution of the utility model is:
A kind of tailings drainage works structure, it is characterized in that: include the tailings storehouse that tailing dam surrounds, smooth clay blanket layer is arranged in the tailings storehouse, and excavation has the latticed filtration ditch of mutual UNICOM in the tailings storehouse, filter the ditch bottom and be covered with grey sand bedding course, repave the antiseepage rete on the ash sand bedding course, repaved the last layer coarse sands layer on the antiseepage rete; Be equipped with the antipriming pipe of mutual UNICOM on the coarse sands layer of described each bar filtration ditch, antipriming pipe is wrapped up filter screen outward, be equipped with geotextiles on the antipriming pipe, lay first floor coarse sands layer, the second gravel pebbles layer, the 3rd gravel pebbles layer, the 4th gravel pebbles layer on the described geotextiles more successively, the gravel pebbles diameter of the second gravel pebbles layer, the 3rd gravel pebbles layer, the 4th gravel pebbles layer increases progressively successively; Complete the back on the 4th layer of gravel pebbles and cover with geotextiles, re-lay several layers of boulder bed on the described geotextiles, end face is equipped with one deck coarse sands layer.
Described tailings drainage works structure, it is characterized in that: the antipriming pipe of described filter ditch is set to discharge structure; Be provided with the open drain around the described tailings storehouse.
Described tailings drainage works structure is characterized in that: described filter trench depth 60cm, and the side slope ratio is 1: 1, described dust and sand cushion thickness is the 5-8 centimetre, the coarse sand bed thickness 6-10 centimetre on the antiseepage rete, coarse sand particle diameter 3-5 millimeter; The thickness of the second gravel pebbles layer, the 3rd gravel pebbles layer, the 4th gravel pebbles layer is the 8-12 centimetre respectively, and the cobble particle diameter is followed successively by 5-10 millimeter, 10-20 millimeter, 20-40 millimeter in each layer.
The utility model adopts novel covering isolation seepage control technique that CHARACTERISTICS OF TAILINGS SAND is carried out the layering isolation, carry out the water filtration of tailings sand, dehydration, drying with the graded sand cobble, the part tailings is used to produce building materials, the tailing water that filters is discharged to ore dressing plant, self-purification, recycling, thereby realizes the dried heap of tailings.
