Description
Technical field
The invention belongs to mine tailing actual mining technology field, and in particular to a kind of dry type stoping method of mine tailing, be particularly suitable for use in
The middle-size and small-size Tailings that Tailings beach face foundation bearing capacity is smaller, it is shorter to require the duration, tailing heap storage is little return
Adopt engineering.
Background technology
At present, China is in Tailings back production, and the mode of mine tailing back production mainly has hydromining, ship to adopt and dry adopts three kinds of sides
Formula.
Hydromining is pressurizeed by means of water pump, and producing the gravity of high-velocity flow motive force with mine tailing in itself by giant will
Mine tailing impact avalanche makes mine tailing is broken apart to be out characterized in that production capacity is big, and cost is relatively low, and screening debris removal equipment is simple,
It is cementing for many years than more serious mine tailing particularly suitable for depositing;But the technical requirements of hydromining are higher, it is necessary to be imitated according to production
Rate and security situation adjust hydraulic giant angle and safe distance in good time.
It is to be exploited using dredger or sand dredger according to the dass of regulation that ship, which is adopted, needs to preset digging before exploitation
Sequentially, digging bandwidth and excavating depth, the certain water level of Tailings Dam domestic demand holding, individual layer working thickness are general when being adopted using ship
In 1.0m or so, it is characterized in that production capacity is big, labor productivity is high, and the concentration of production is easy to manage;Shortcoming is use condition
Compare strictly, had a great influence by reservoir area landform, lithology and temperature.
It is dry to adopt i.e. machine instruction statement mining, mine tailing is excavated using excavation equipments such as bull-dozer and excavators, then it is straight by loading machine
Connect and mine tailing is loaded into means of transport, be characterized in simple production process, flexibly, management is easier, and applicability is also relatively strong,
But required to influence by foundation bearing capacity, dry adopt is generally required when mine tailing beach face consolidation strength meets that plant equipment admission is minimum
It can be exploited after it is required that.Such as《Modern Mineral》Weight in 2 months the 2nd phases in 2013 " engineering practice of mine tailing safety coal extraction " text
Point describes mine tailing stoping scheme, and the stoping scheme uses the strip mining transformation side of " excavator adopts dress+belt-conveying+Automobile Transportation "
Formula, carry out draining first in Tailings Dam, consolidate mine tailing, equipment is felled and transported under mine tailing drainage state, be directly loaded up
Outward transport, or reprint, to after interim stockyard, twice loading outward transport.The stoping scheme technique is simpler, but equally exists Tailings Dam
Draining, mine tailing consolidation, the problem of time of mine tailing drainage is long, Tailings Dam back production time length.
The content of the invention
The purpose of the present invention aiming above mentioned problem existing for prior art, and provide one kind can quickly, efficiently, it is big
Complete to scale the new method of the Tailings dry type back production of Tailings back production engineering.
To realize the purpose of the present invention, a kind of new method of Tailings dry type back production of the invention by following technique,
Step is realized:
1) Tailings Dam is investigated:To tailings warehouse dam body stability, mode of drainning off floodwaters, flood drainage system validity, Tailings Dam beach face
Base carrying force intensity, reservoir area depth of accumulated water carry out system investigation, and basic data is provided for tails dry back production.
2) construction road laying and back production Division:Laid using rubble from tailings warehouse dam body to Tailings Dam gully direction
Interim granular-type road is as temporary construction road, and have a lot of social connections 4-10m in road, higher than Tailings Dam beach face 0.8-1.2m;That lays is interim broken
Stone road, to the tailings warehouse dam body of surrounding into radial arrangement, whole Tailings Dam beach face is divided into centered on Tailings Dam gully
Several regions, the angle between adjacent interim granular-type road are true according to the distance of Tailings Dam gully and tailings warehouse dam body dam facing
It is fixed.
Angle between adjacent interim granular-type road is typically between 5-20 °.When Tailings Dam gully and tailings warehouse dam body
During distance L≤100m of dam facing, the angle between adjacent interim granular-type road takes 15-20 °;When Tailings Dam gully and Tailings Dam
During 100 < L≤150m of distance of dam body dam facing, 10-15 ° of angle between adjacent interim granular-type road;When Tailings Dam gully
During with the distance L > 150m of tailings warehouse dam body dam facing, the angle between adjacent interim granular-type road takes 5-10 °.
3) mine tailing is transported using artificial or small-sized machine excavation in the 15m of Tailings Dam gully periphery, and hand excavation's depth is
0.5-1.5m, small-sized machine cutting depth 1.0-3.0m, make in Tailings Dam gully periphery 15m as the minimum of Tailings Dam beach face
Point, it is easy to storehouse internal water accumulation discharge.
The mini-excavator tool refers to quality < 10.0T, bucket capacity < 0.5m3Excavator.
4) temporary drain is excavated in both sides of the road using excavation machinery, temporary drainage ditch depth 1.0-1.5m is wide
1.0-2.0m, 0.5%-2.0% descending grade is formed to Tailings Dam gully direction, is easy to reservoir area beach face ponding to gully direction
Collect, to accelerate storehouse internal water accumulation discharge.
Described excavation machinery refers to the excavator of various models, sliding loader etc..
5) after reservoir area internal water accumulation drains, using the larger excavating machinery of the radius of clean-up to interim granular-type road both sides Tailings Dam
Treat that back production mine tailing carries out subregion excavation under beach face, cutting depth control is in cutting depth in the range of 15m around 1-4m, gully
3-6m, the progress back production of next region is entered after back production is completed in a region, until this layer of all areas mine tailing back production is completed.
6) after one layer of mine tailing back production terminates, interim granular-type road is excavated, takes its rubble interim in its side laying lower floor
Granular-type road, and lower floor's temporary drain is excavated, repeat above-mentioned 5) step and the mine tailing of the interim granular-type road both sides of lower floor is carried out
Subregion excavates, until Tailings full extraction terminates.
Described rubble is waste mining rock, outsourcing block stone, the one or both in the barren rock of refuse dump, the mixture of three,
The uniaxial compressive strength of rubble is 10-60Mpa, particle diameter 2-30cm.
A kind of new method of Tailings dry type back production of the present invention, after above technical scheme, have following positive
Effect:By investigating Tailings Dam, temporary road laying, excavating machinery is directly entered Tailings Dam central area progress tailings and opened
Adopt, accelerate Tailings Dam drawing speed, shorten the exploitation duration, solve the problems, such as that the conventional dry back production effective time is short,
Reduce dry type back production requirement to foundation bearing capacity in Tailings Dam application, so as to it is quick, efficiently, complete mine tailing on a large scale
Storehouse tailings actual mining, Tailings Dam tailings back production efficiency is improved, reduce stoping cost, save the back production time, had extensive suitable
Ying Xing.
