The invention discloses a kind of Tailings Dams to close library system and method, photovoltaic generating system, ecological restoring method, wherein, it is related to closing Tailings Dam into library system, photovoltaic generating system and restoration of the ecosystem triplicity, the dam body in library is closed by Tailings Dam, deposit the regulation of beach face and drainage system, it recycles discarded stone and tailings is used as and closes library material, photovoltaic generating system is installed in closing library system, CHARACTERISTICS OF TAILINGS SAND matrix is improved as planting matrix and breeding suitable species simultaneously, realize Tailings Dam, rejected ore, goaf, collapse the safety improvement that discarded place has been polluted in decanting zone etc., comprehensive utilization and ecological protection.
Description
Technical field
The present invention relates to the present invention relates to Tailings Dam Treatment process fields, and in particular to a kind of Tailings Dam closes library system and side
Method, photovoltaic generating system, ecological restoring method.
Background technique
Currently, the Tailings Dam in some mines, abandoned mine library, dregs stockyard, goaf, to collapse the large area such as decanting zone idle.
When Tailings Dam closes library improvement at present, ore resources comprehensive utilization in tail library is insufficient.Library is closed to administer and subsequent comprehensive utilization and life safely
State reparation is kept completely separate, or does not carry out comprehensive utilization and restoration of the ecosystem.
Summary of the invention
The present invention is directed at least solve one of the technical problems existing in the prior art.For this purpose, one object of the present invention
It is to propose that a kind of Tailings Dam closes library system, reasonably takes full advantage of the obsolete material of Tailings Dam, saved resource, realize
The safety of Tailings Dam is administered.
The present invention also proposes that a kind of Tailings Dam closes library method, reasonably takes full advantage of the obsolete material of Tailings Dam, saves
Resource, the safety for realizing Tailings Dam are administered.
The present invention also proposes a kind of photovoltaic generating system, realizes the comprehensive utilization that Tailings Dam closes library and photovoltaic power generation.
The present invention also proposes a kind of ecological restoring method, realizes and carries out ecology improvement and recovery after closing library to Tailings Dam；
Or it realizes Tailings Dam and closes the comprehensive utilization of resources that library, photovoltaic power generation and restoration of the ecosystem combine.
The Tailings Dam of embodiment closes library system according to a first aspect of the present invention, comprising:
Beach face coating is deposited, the deposition beach face coating is laid on the deposition beach face using tailings and is formed
Tailings layer；
Dam body, the dam body are disposed around the outside of the deposition beach face coating；The dam body includes outer slope protection layer,
The outer slope protection layer is not produce the slope protection layer that sour barren rock is built into using coarse grain diameter；
Gutter, the gutter include library week gutter and library internal drainage ditch；The library week gutter be looped around it is described
The outside of dam body and adjacent with the dam body；The library internal drainage ditch is located at the deposition beach face coating and the dam body
Surface on, and intersect with library week gutter and be connected to, pass through the convergence gutter row being located on the outside of library week gutter
Out.
The Tailings Dam of embodiment closes library system according to a first aspect of the present invention, and deposition beach face coating is being deposited using tailings
Beach face is laid with, and dam body, which encloses, to be built in the outside of deposition beach face coating, and the outer slope protection layer of dam body is not produced using coarse grain diameter
Sour barren rock is built into, and the surface layer for depositing beach face coating and dam body is equipped with library internal drainage ditch and is connected to library week gutter, passes through position
Convergence gutter discharge on the outside of library week gutter.Any facility for not changing and destroying Tailings Dam not only as a result, also increases
Tailings warehouse dam body regulation, deposition beach face improvement, gutter facility etc., and reasonably take full advantage of the discarded material of Tailings Dam
Material, has saved resource, is conducive to restoration of the ecosystem, closes that library system is safe and reliable, so that the safety for realizing Tailings Dam is administered.
The coarse grain diameter of one embodiment according to a first aspect of the present invention, the outer slope protection layer does not produce sour barren rock
Partial size is greater than 200mm.
One embodiment according to a first aspect of the present invention, the outer slope protection layer with a thickness of 0.4~0.6m.
One embodiment according to a first aspect of the present invention, the gutter are not produce sour mine barren rock and water using fine grain
Gutter made of cement mortar mixing is built.
Further embodiment according to a first aspect of the present invention, the fine grain do not produce sour mine barren rock partial size be 5mm~
60mm。
The Tailings Dam of embodiment closes library method according to a second aspect of the present invention, includes the following steps:
The processing of mine barren rock；According to the physicochemical characteristics of mine barren rock, selection does not produce sour mine barren rock and carries out break process, obtains
Coarse grain diameter does not produce that sour barren rock, fine grain do not produce sour barren rock, middle fine grain does not produce sour barren rock, closes library material as Tailings Dam and uses；
Deposit beach face processing: it is smooth to deposition beach face progress, then it is laid with tailings in deposition beach face, it forms deposition beach face and covers
Layer；
It builds dam body: dam body being built using native stone in the outside of deposition beach face, slope is not produced using coarse grain diameter outside dam body
Sour mine barren rock is built into slope protection layer；
It builds gutter: building library week gutter in dam body outside and with dam body adjacent；In deposition beach face coating
Library internal drainage ditch is built into using fine grain not produce sour barren rock and mix with cement mortar on the surface of dam body, the library internal drainage
Ditch intersects with library week gutter to be connected to, the convergence gutter discharge on the outside of library week gutter.
The tailing of embodiment closes library method according to a second aspect of the present invention, is laid with to form deposition using tailings in deposition beach face
Beach face coating encloses body of building a dam in the outside of deposition beach face coating, and the outer slope protection layer of dam body does not produce acid using coarse grain diameter
Barren rock is built into, and the surface layer for depositing beach face coating and dam body is equipped with library internal drainage ditch and is connected to library week gutter, by being located at
Convergence gutter discharge on the outside of library week gutter.Do not change and destroy any facility of Tailings Dam not only as a result, also increase tail
The regulation of mine library dam body, deposition beach face improvement, gutter facility etc., and reasonably take full advantage of the mine barren rock of Tailings Dam and give up
Tail dropping sand has saved resource as library material is closed, and is conducive to restoration of the ecosystem, so that finally obtained library system of closing is repaired conducive to ecology
