Description
Technical field
The invention belongs to underground mining method technical field, more particularly to a kind of Upward slicing of extremely thick big firm ore body to fill
Fill out mining methods.
Background technology
It is very thin ore body generally by ore body division during orebody mining（Thickness ＜ 0.8m）, lean ore body（0.8m≤thickness
Spend ＜ 4.0m）, middle thickness orebody（4.0m≤thickness ＜ 10m）, big thick ore body（10.0m≤thickness ＜ 40.0m）, pole big thick ore body
（Thickness >=40.0m）Deng according to the scientific and reasonable recovery method of the thickness parameter of ore body and its occurrence condition selection.
It is different according to the mode of underground pressure management in underground mine production technique field, underground mining method is divided into three kinds：
Openstope method, the method for mining by the way of filling, caved stopes.
The first kind, openstope method.Nugget is divided into mineral building and ore pillar by this method, in two steps rapid exploitation.During rooming
The goaf formed, safeguarded using the intensity of ore pillar and ore-rock in itself.
Second class, the method for mining by the way of filling.Most of mining methods of this class, also it is divided into two steps and carries out back production.Back production ore deposit
Fang Shi, with the propulsion of stope, progressively with casting resin bashing, country rock slabbing is prevented, i.e., with bashing
Method management ground pressure.
3rd class, caved stopes.This class mining codes are a step back production, and with the propulsion of stope, together
When avalanche country rock be full of goaf, so as to the reaching management and control purpose pressed.
The content of the invention
The purpose of the present invention does not allow the extremely thick ore body firm greatly of avalanche for earth's surface, reasonable cutting and utilizes underground mining
Space, production technology linking compact neat, using heavy mechanical equipment and trackless equipment, labor productivity is high, and ore losses is poor
Change the overhand slicing mining methods for being suitable for extremely thick big firm ore body of the features such as small.
The purpose of the present invention is to be achieved through the following technical solutions.
A kind of overhand slicing mining methods of extremely thick big firm ore body of the present invention, including ore body division and adopt quasi- system
System, it is characterised in that comprise the following steps：
The first step：Ore body across pitch is divided into nugget, the mineral building and ore pillar arranged in nugget, the vertical thickness of a width of ore body of nugget
Degree；Adopt Barebone and returned including being segmented connection roadway, layering connection roadway, exploiting field air intake courtyard and exploiting field along the pulse outside arteries and veins outslope road, arteries and veins
Wind courtyard；
Second step：Exploited using upward ut and fill stoping, separate zone production from bottom to top in nugget, each sublayer height
4m-5m, the m-2m of unsupported back span 1, one layer is adopted, fill one layer, a layering connection roadway is set in each layering, every five are layered as one
Individual segmentation, each layering connection roadway are communicated by being segmented connection roadway along the pulse outside an arteries and veins with arteries and veins outslope road；
3rd step：Horizontal vertical blasthole is bored using hydraulic drill ring in stope, millisecond short delay blasting is used per separate explosion
Multiple rows of blasthole；
4th step：It is fresh it is distinguished and admirable through exploiting field air intake courtyard, be segmented connection roadway, layering connection roadway along the pulse outside arteries and veins and enter ore stope,
Waste air behind cleaning face drains into top return air level through exploiting field return air raise；
5th step：Hair is prized to empty jacking row after ore stope ventilation, to ensure exploitation safety；
6th step：Actual mining is carried out after falling ore deposit, ore is directly loadable into underground truck by scraper, then by underground truck through adopting
Area arteries and veins outslope road is transported to discharge station and is discharged into main chute；
7th step：After each layering ore stope mining terminates in nugget, horse back clearing and retrieving ore stope sill residual ore body
Stone, filling counterfort is built up using barren rock or tailings bag in ore stope surrounding, filling pipeline is then accessed by filling well and transferred
Casting resin is filled, and each be layered in ore stope first fills the thick low concentration cemented filling materials of 3m-4m, described low concentration
Cemented filling material is tailings and barren rock, and its cement-sand ratio is 1:6 ~ 8, highly concentrated cemented fill material thick refilling 1m-2m is described
The cement-sand ratio of highly concentrated cemented fill material is 1:4 ~ 6, the equipment availability face as a upper slicing, so repeatedly, until whole
Individual block stoping finishes, after sky withstands on whole nugget complete extraction, then with highly concentrated cemented fill material Tight filling.
Described low concentration cemented filling material is tailings and barren rock, cement-sand ratio 1:6~8；Described highly concentrated cemented fill
Material, cement-sand ratio 1:4~6.
Described nugget length 99m, wherein mineral building 95m, ore pillar 4m.
Length × width × height=45m × 18m × 4m of every layer of described ore stope.
The beneficial effects of the invention are as follows：
Using the characteristics of stope is more, space is big in downhole card car maneuverability and nugget, greatly meet the effective continuous of shovel shipment
Operation and each operation orderly rotation in different stopes, and stope box and rail mounted transport system are not set, greatly shorten mine
Production time and up-front investment, improve shovel shipment efficiency, reduce ore loss and dilution.
