Description
Technical field
The invention belongs to mine tailing actual mining technology field, be specifically related to the dry type back production side of a kind of mine tailing
Method, is particularly suited for that Tailings beach face foundation bearing capacity is less, requires that the duration is shorter, tail
The middle-size and small-size Tailings back production engineering that ore deposit volume of cargo in storage is little.
Background technology
At present, China in Tailings back production, the mode of mine tailing back production mainly have hydromining,
Ship is adopted and dry adopts three kinds of modes.
Hydromining is by mean of water pump pressurization, produces high-velocity flow motive force and tail by giant
Mine tailing is impacted avalanche by the gravity in ore deposit itself makes mine tailing broken apart out, is characterized in producing energy
Power is big, and cost is relatively low, and screening debris removal equipment is simple, is particularly suitable for depositing the most cementing comparison
Serious mine tailing；But the technology of hydromining requires higher, need according to production efficiency and safety
Situation adjusts hydraulic giant angle and safe distance in good time.
It is to use dredger or sand dredger to exploit, before exploitation according to the dass of regulation that ship is adopted
Digging order, dass width and excavating depth need to be preset, when using ship to adopt in Tailings Dam
Need to keep certain water level, monolayer working thickness, typically at about 1.0m, is characterized in producing
Ability is big, and labor productivity is high, and management is easy in the concentration of production；Shortcoming is that use condition compares
Strictly, affected bigger by reservoir area landform, lithology and temperature.
Dry i.e. machine instruction statement mining of adopting, uses the excavation equipment such as bull-dozer and excavator excavation mine tailing, then
Directly mine tailing is loaded means of transport by loading machine, be characterized in that production technology is simple, spirit
Living, Comparison of Management is easy, and the suitability is the strongest, but is required to affect by foundation bearing capacity,
Dry adopting generally requires after mine tailing beach face consolidation strength by the time meets plant equipment admission minimum requirements
Can exploit.Such as phase " mine tailing safety coal extraction in " Modern Mineral " February the 2nd in 2013
Engineering practice " literary composition introduces mine tailing stoping scheme, this stoping scheme uses " to be excavated
Dress+belt-conveying+Automobile Transportation adopted by machine " strip mining transformation mode, first enter in Tailings Dam
Row draining, makes mine tailing consolidate, and makes equipment fell and transport under mine tailing drainage state, is directly loaded up
Outward transport, or reprint, behind interim stockyard, twice loading is transported outward.This stoping scheme technique is simpler
Single, but equally exist the problem of the time length of Tailings Dam draining, mine tailing consolidation, mine tailing drainage,
The Tailings Dam back production time is long.
Summary of the invention
The purpose of the present invention is aiming at the problems referred to above that prior art exists, and provides a kind of energy
Enough Tailings dry types completing Tailings back production engineering quickly, efficiently, on a large scale
The new method of back production.
For realizing the purpose of the present invention, the new method of the present invention a kind of Tailings dry type back production
Realized by following technique, step:
1) Tailings Dam investigation: tailings warehouse dam body stability, mode of drainning off floodwaters, flood drainage system are had
Effect property, Tailings Dam beach face foundation bearing force intensity, reservoir area depth of accumulated water carry out system investigation, for
Tails dry back production provides basic data.
2) construction road is laid and back production Division: use rubble from tailings warehouse dam body to mine tailing
Gully direction, the storehouse interim granular-type road of laying 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；The interim granular-type road laid with Tailings Dam gully is
Center becomes radial arrangement to the tailings warehouse dam body of surrounding, is divided into some by whole Tailings Dam beach face
Individual region, the angle between adjacent interim granular-type road is according to Tailings Dam gully and tailing dam
The distance of body dam facing determines.
Angle between adjacent interim granular-type road is typically between 5-20 °.When Tailings Dam is arranged
During the distance L≤100m of well and tailings warehouse dam body dam facing, between adjacent interim granular-type road
Angle takes 15-20 °；Distance 100 ＜ L when Tailings Dam gully Yu tailings warehouse dam body dam facing
Angle 10-15 ° during≤150m, 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
Take 5-10 °.
3) in Tailings Dam gully periphery 15m, mine tailing uses manually or small-sized machine excavation transports,
Hand excavation's degree of depth is 0.5-1.5m, and small-sized machine cutting depth 1.0-3.0m makes Tailings Dam
The minimum point of Tailings Dam beach face is become, it is simple to storehouse internal water accumulation is discharged in gully periphery 15m.
Described mini-excavator tool refers to quality ＜ 10.0T, bucket capacity ＜ 0.5m3Excavator.
4) excavation machinery is utilized to excavate temporary drain, temporary drain in road both sides
Deep 1.0-1.5m, wide 1.0-2.0m, form 0.5%-2.0%'s to Tailings Dam gully direction
Descending grade, it is simple to reservoir area beach face hydrops collects to gully direction, to accelerate storehouse internal water accumulation discharge.
Described excavation machinery refers to the excavator of various model, sliding loader etc..
5), after reservoir area internal water accumulation drains, utilize the excavation machinery that the radius of clean-up is bigger to the most broken
Back production mine tailing for the treatment of under the Tailings Dam beach face of stone road both sides carries out subregion excavation, and cutting depth controls
Cutting depth 3-6m in the range of 15m around 1-4m, gully, when a region completes back
Enter next region after adopting and carry out back production, until this layer of all regions mine tailing back production completes.
6) after one layer of mine tailing back production terminates, interim granular-type road is excavated, take its rubble at it
The interim granular-type road of lower floor is laid in side, and excavates lower floor's temporary drain, repeats above-mentioned 5)
The mine tailing of step granular-type road interim to lower floor both sides carries out subregion excavation, until Tailings
Full extraction terminates.
Described rubble be the one or both in waste mining rock, outsourcing block stone, refuse dump barren rock,
The mixture of three, the uniaxial compressive strength of rubble is 10-60Mpa, particle diameter is 2-30cm.
The new method of the present invention a kind of Tailings dry type back production, uses above technical scheme
After, have the positive effect that: by investigating Tailings Dam, temporary road is laid, excavator
Tool is directly entered Tailings Dam central area and carries out tailings mining, accelerates Tailings Dam drawing speed,
Shorten the exploitation duration, solve conventional dry back production effective time short problem, reduce
Dry type back production requirement to foundation bearing capacity in Tailings Dam is applied, thus quickly, efficiently, greatly
Complete to scale Tailings Dam tailings actual mining, improve Tailings Dam tailings back production efficiency, reduce back
Adopt cost, save the back production time, there is adaptability widely.
