Description
Technical field
The utility model belongs to mine tailing dilatation facility.
Background technology
What Tailings Dam referred to that build a dam the interception mouth of a valley or exclosure form carries out in order to store up metal and nonmetal mine the place that ore sorts rear discharge mine tailing, is maintain the necessary facility normally produced of mine, but is also the major hazard source in metal and nonmetal mine.The accident of letting out under Tailings Dam dam break over the past two years and Toxic occurs repeatedly, causes that heavy losses are environmentally safe to constitute a serious threat to people's life's property.
The research of Clark University's public hazards evaluation group of the U.S. shows, the harm of Tailings Dam accident ranks the 18th in the hidden danger of 93 kinds, world accident, public hazards.It is only second to nuclear weapon blast, DDT, nerve gas, nuclear radiation and other 13 kinds of disasters and more serious than other 60 kinds of disasters such as aircrush, fire.According to first-class Tailings Dam 27 in the national Tailings Dam of statistics, second-class Tailings Dam 49, third-class Tailings Dam 291, fourth class Tailings Dam 1081, five Tailings Dams such as grade 4022, not clear Tailings Dam 146, does not fill in 1896, wherein endanger 19, storehouse, 61, dangerous storehouse, 445, sick storehouse, normal 4587, storehouse, not clear 40, do not fill in 2767.
The Tailings Dam that China's metal, non-metal mine ore dressing plant are used, mostly be built in the 60 to 70's of twentieth century even more early, use through long-term heap sum, substantially, be in the limit that Tailings Dam stores volume at present, and the limitation of technology and the lack of standardization of management at that time, making a part of tailing storehouse there is certain potential safety hazard, if do not solved as early as possible, even can occur the danger that tailing dam caves in, mine tailing breaches a dyke at any time.In order to safeguard that the normal continuously of mine is produced, each bargh, designer and researcher, doing one's utmost the preferred plan of seeking the storage of mine tailing later stage, to solve the storage problem that continues of mine tailing.The approach of current solution: one is newly-built Tailings Dam, two is transformation tailing storehouses.If a newly-built Tailings Dam, there is the problem that investment is many, expropriation of land is difficult, ambient influnence is large, the construction period is long.If by existing Tailings Dam elevation and expansion, because existing Tailings Dam generally adopts " upstream type " Tailing dam construction, containing multi-level sludge interlayer in dam body, cause dam seepage line high, structural strength is low, and dam stability is poor.If continue to be undertaken increasing storage capacity by " upstream type " mode of building a dam, then not only engineering difficulty is large, and the storage ore deposit finite capacity that can expand by the restriction of tailing dam high dam stability.
Utility model content
The purpose of this utility model is to provide a kind of structure simple high-risk storehouse capacity-enlarging system, to solve the problem of the dam stability difference that existing Tailings Dam elevation and expansion exists.
The technical solution that the utility model is taked is: a kind of high-risk storehouse capacity-enlarging system, comprise initial dam, Tailings Dam body, in the early stage dam and Tailings Dam body are arranged respectively and increase initial stage dam body and crude tailings body, Tailings Dam row seepage well is provided with in Tailings Dam body, the bottom of Tailings Dam row seepage well is connected with horizontal seepage pipe, and the middle and upper part sidewall of Tailings Dam row seepage well is provided with the permeable circle of at least one deck.
Preferably, described permeable circle is followed successively by open pore steel plate, sandstone loaded filter and geotechnological layer of cloth from the inside to the outside.Preferably, described open pore steel plate and sandstone loaded filter are at least two-layer.
The utility model lays large-scale combined type Tailings Dam row seepage well, reduce phreatic line, recycling crude tailings heap is stored on the outer slope of existing Tailings Dam, reinforce existing Tailings Dam, while reduction phreatic line speedily carries out rescue work improvement Tailings Dam, increase the volume of Tailings Dam, extend the length of service of Tailings Dam, achieve twice laid, greatly reduce engineering cost, avoid investment and the occupation of land of newly-built Tailings Dam, there is Tailings Dam dilatation amount large, tailing dam security and stability is good, engineering construction is convenient, to gather materials on the spot the many advantages such as to reduce expenses, there is very large economic benefit and significant social benefit.
