The prevention and treatment method of the water scour hazards of the binding site of the mine solid waste yard and the mountain area has the advantages of being capable of effectively preventing the binding site of the mountain area and the solid waste yard from water scour, reducing water loss and soil erosion, protecting the environment and preventing landslides and debris flow hazards.
Description
Technical field
The present invention relates to a kind of method of preventing and treating mine solid waste storage yard water and wash away unstability, belong to mine safety engineering field, be applicable to the mine of all kinds of heap row solid waste, utilize the method can reach reasonable draining, prevent from washing away, reduce soil erosion, the object of control landslide, mud-stone flow disaster, the safe operation while ensureing Mine Solid Wastes heap row.
Background technology
The flow processs such as mine capital construction, mining, ore dressing produce a large amount of solid waste, mainly comprise barren rock soil, beneficiation tailing soil and the dump leaching slag peeled off.China is the large selecting and purchasing solid waste discharge of the first in the world big country, metallurgical opencut dumps approximately 2,000,000,000 tons of barren rock amounts every year, mine tailing reserves exceed 10,000,000,000 tons, and newly-increased mine tailing 8～1,000,000,000 ton every year, and along with the reduction of the increase of To Mining Development scale and milling ore grade, these numerals also will increase year by year, and barren rock, mine tailing quantity that accumulative total is stored up are huger.A large amount of solid waste discharges not only take valuable land resources, cause the deterioration of the ecological environment, and be come down, the dangerous matter sources of the geological disaster such as mud-rock flow, threat to life property safety.
Mine Solid Wastes is the huge artificial loose depos-its body of one forming in the activity in production of mine, in order to reduce floor space, is often deposited in available mountain valley.The stability of accumulation body depends on the many factors such as the physico-mechanical properties of structural parameters, ground and stacking material thereof of itself and the size of the distribution of seepage field, dynamic loading.In these influence factors, for loose media, the effect of water is particularly remarkable.Along with the raising of awareness of safety, anti-drainage measure is mostly taked to artificial loose depos-its body in mine, as catchwater is set, and builds horizontal drainage ditch, builds horizontal drainage ditch etc. at platform middle part, and this has improved the stability of accumulation body to a certain extent.As Chinese patent application 201210214485.5 discloses a kind of surface mine refuse dump slope treatment method, it is 1 that grade of side slope is arranged: 1.5-1: 3, and cohesive soil is got 1: 1.5, and grit stone is got 1: 3, and other great soil group is got median; Build platform: the every rising 6-12m of vertical height builds levelling bench, and width is 5m; Build horizontal drainage ditch: build horizontal drainage ditch at platform middle part; Build drain way: horizontal direction is built a drain way perpendicular to horizontal drainage ditch every 30m on domatic, the gradient is depending on location precipitation size, northern α=2-3 °, southern α=3-5 °; If top, the refuse dump gradient does not reach aforementioned requirement, build net of canals and ditches at top; Vegetation slope pavement.To transforming by limited engineering and biological control measure on original refuse dump, can effect a radical cure the potential safety hazard of surface mining refuse dump, soil erosion is greatly alleviated, improve the ecological environment, beautify mining area and surrounding enviroment.But the binding site of accumulation body and massif often becomes blind spot, carries no weight.In the time that accumulation body heap is discharged to massif junction, be subject to the impact of massif charge for remittance, be vulnerable to washing away in various degree.Wash away gently, can cause soil erosion; Wash away heavy, cause talus slide, mud-stone flow disaster etc. even can occur.For anti-sealing is to the washing away of binding site, the generation of control landslide, mud-stone flow disaster, improves the stability of accumulation body, proposes a kind ofly to prevent and treat the method that mine solid waste and massif binding site water washes away harm and be especially necessary.
Summary of the invention
Object of the present invention is exactly the problems referred to above that exist for prior art and a kind of method of preventing and treating solid waste stockyard, mine and massif binding site water and wash away harm is provided, and the method can reduce soil erosion, in advance landslide-proofing, mud-stone flow disaster.
For realizing above-mentioned purpose of the present invention, the present invention is a kind of prevents and treats method that solid waste stockyard, mine and massif binding site water washes away harm by the following technical solutions:
Binding site in massif and solid waste stockyard is built catchwater, and catchwater is topping bar to repair and get out of a predicament or an embarrassing situation most from solid waste stockyard most according to orographic condition; On each step, have step gutter; Step gutter UNICOM catchwater forms multistage zonule drainage system; Leftover bits and pieces at massif and binding site two ends, solid waste stockyard is built sump, sump and water discharge tunnel UNICOM; The charge for remittance in solid waste stockyard, original massif region is guided to sump by the multistage zonule drainage system that step gutter and catchwater form, and draws solid waste stockyard through water discharge tunnel.The design of step gutter, catchwater, water discharge tunnel, sump must meet code requirement.
The longitudinal bottom of trench of described catchwater adopts stepped, and this structure can play energy dissipating effect; Sump has concurrently and catchments and dissipating functions.
Described step gutter adopts open channel form, rectangular cross section, and two sides inwall grouts with piece stone, bottom of trench cement coating; Described catchwater adopts open channel form, trapezoidal cross-section, and ditch two sides inwall grouts with piece stone, bottom of trench cement coating; Water discharge tunnel, employing circular arch stalk type, concrete lining; Sump adopts concrete structure.
The gradient in described gutter is 0.9%-1.2%, and the gradient of water discharge tunnel is 1.4%-1.7%.
The drainability of described water discharge tunnel is greater than whole solid waste accumulation area and checks peak flood flow.
The present invention is a kind of to be prevented and treated the method that solid waste stockyard, mine and massif binding site water washes away harm and adopts after above technical scheme; effectively prevent water washing away massif and solid waste stockyard binding site; reduce soil erosion; protect environment, pre-landslide-proofing, mud-stone flow disaster have been played to key effect.
The present invention is a kind of method of preventing and treating solid waste stockyard, mine and massif binding site water and wash away harm, binding site in massif and solid waste stockyard is built catchwater, and be interconnected with each step gutter, form multistage zonule drainage system, charge for remittance is discharged to sump, deflect from solid waste accumulation body region through water discharge tunnel, widely applied at certain opencut.Application in practice shows, the method can efficient anti-sealing to the washing away of binding site, guaranteed Mine Solid Wastes heap row's safe operation.
