Description
Technical field
The present invention relates to the anti-soil technology of water resource, especially relate to a kind of mining tailing wasteland structure of the row's of oozing type bilge water resisting resource regeneration.
Background technology
According to statistics, the industrial solid wastes total amount of the annual discharging of whole world extractive industry reaches tens billion of tons, in China, and about 6.20 hundred million tons of the barren rock mine tailing of the annual discharging of ferrous metal mine, the annual barren rock mine tailing of discharging of nonferrous metal mine reaches 1.15 hundred million tons, about 1.30 hundred million tons of gangue.The a large amount of dischargings arbitrarily and the accumulation dam site of these chats, mine tailing are arranged unreasonable, heavy damage the natural ecological environment of land resources, not only occupy a large amount of soils, destroy natural landscape, and its composition is very complicated, contains multiple harmful components even radioactive substance, by media severe contamination mining areas such as water, air and soil and underground water, river and farmland on every side, in addition, stack chats, mine tailing instability, cause that easily talus moves and disaster such as mud-rock flow.
The comprehensive regulation of mine tailing bilge water resisting resource regeneration is the major issue that concerns environment for human survival.Processing to mine tailing is to carry out collection and treatment with the form of building tailing dam formation mining tailing wasteland mostly at present, moisture content leans on natural evaporation and infiltrates soil naturally in the mine tailing, its discharging only relies on simple pipe of cement discharging, is difficult to accomplish the pollution-free collection of mine tailing, and moisture content non-pollution discharge in the mine tailing.And because moisture content is difficult to effective discharging in the mine tailing, tailing dam is prone to outer infiltration, very easily bursts, and forms accident potential.
Summary of the invention
Technical problem to be solved by this invention is the present situation of administering at tailings pollution, a kind of mining tailing wasteland structure of oozing row's type bilge water resisting resource regeneration is proposed, emphasis solves regeneration, the collection and recycling of moisture content in the mine tailing, to stop mining tailing wasteland by the be rivals in a contest pollution of environment of water, soil media and tailings pile.
Technical problem of the present invention is solved by following technical scheme:

Overlap joint between described splash guard and plate width at least is 5cm, adopts the inflation check, and air tight is up-to-standard.
The described gutter that oozes is the gutter that oozes that diameter is at least φ 4.5cm, and its spacing is 0.4m～0.5m.Every joint length is 2m or 4m.
Described rubble inserts is that volume is the rubble inserts of long (2～4) m * wide (0.4～0.5) m * height (0.04～0.05) m, is used for filling and oozes space between gutter.
The cement-sand ratio of described cement sand bed is 1: 3, and thickness is at least 0.5cm.
Overlap joint between described geotextiles and cloth width at least is 10cm, and fixing coarse sand and the rubble of adopting in bottom presses solidly, Dou slope and the fixing dedicated fixed bail that adopts of vertical plane.
Described gutter is that diameter is the gutter of φ 15cm～φ 20cm, and its spacing is 0.8m～1.2m.
Technical problem of the present invention is also solved by following further technical scheme:
At auxilliary fixing permeable woven cloth or the permeable straw mats of pasting in exposed geotextiles surface.
Adopt the polysulfide sealant sealing in pre-buried tailing dam junction of oozing gutter.
In filtering ponds, be provided with the spongy layer that secondary filter is used, perhaps be provided with sponge and active carbon interlayer that secondary filter is used.
Compared with prior art, the advantage that the present invention had sees the following form with effect: this table is by the design of 20 years reservoir areas, discharges 1,000 tons the mining tailing wasteland structure of oozing row's type bilge water resisting resource regeneration and having now of identical scale mine tailing day and build the antifouling pond of precipitation throw in the antifouling method of water purification agent and carry out technical performance and contrast outside mining tailing wasteland.
Contrast shows: the present invention adopt have the hot strength height, high density polyethylene (HDPE) splash guard that anti-puncture ability is good, the antiseepage ability is strong and thermal deformation is little characteristics and thickness are at least 2.0mm is as the ground of reservoir area sealing, ooze gutter and geotextiles double filtration discharging, the little filtration of filtering ponds secondary, emphasis have solved the regeneration of moisture content in the mine tailing, collection and recycling.The present invention can effectively stop in harmful chemical in the mine tailing, heavy metal element and the mine tailing moisture content and stack by water, soil media and mine tailing and invade reservoir area underground water and peripheral river, soil and massif, reaches the antifouling effect of remarkable improvement mine tailing.Mining tailing wasteland structure of oozing row's type bilge water resisting resource regeneration of the present invention, the instant antifouling discharging of energy, instant regeneration, safe and reliable, the overall efficiency height, integrated cost is low, and the water in the clear water reserviors can reenter production link and use.
