Abstract
The invention relates to a mining method of an inclined medium-thickness blind ore body, which treats the whole ore body as an ore block, wherein the height of the ore block is the full height of the ore body, the width of the ore block is the trend length of the ore body, and no ore pillar is left in the ore block. Excavating ore removal cross roadways to the bottom of the ore body from the transportation roadway every 5-10 m, and excavating ore removal trenches at the bottom of the ore body; tunneling a pedestrian rock drilling blind inclined shaft 3-8 m away from the boundary of ore body footwall ore rock, and communicating the pedestrian rock drilling blind inclined shaft with an air return roadway; a track is arranged in the pedestrian rock drilling blind inclined shaft, a winch is arranged in the air return roadway, and the winch controls the rail cage to move up and down in the pedestrian rock drilling blind inclined shaft through a steel wire rope. Workers drill fan-shaped blast holes in a layered mode into a mine body in a rail cage, the fan-shaped blast holes are drilled in a layered mode through layered blasting, and the collapsed ores are conveyed out of a haulage roadway from an ore removal trench through an ore removal cross roadway through a scraper. Has the advantages that: a large amount of mining preparation projects during the mining by a sectional open stope method are replaced, the investment of the mining preparation projects is saved, the process is simple, and the efficiency is high.
Description
Technical field
The invention belongs to underground mining method technical fields, and in particular to a kind of Medium Thickness And Medium Slope Angle blind orebody recovery method.
Background technique
Compared with other mining powers of the world, Mineral Resources in China preservation has large mineral resources such as apparent copper, iron
Quantity relative deficiency, the small rare mineral rich in mineral resources of the dosages such as tungsten, antimony；Large and super-large deposits are few, middle-size and small-size mineral deposit
The features such as more.The special resource enrichness status in China determines in bargh's production often finds geologic map by mother-lode
In the blind squat that does not state clearly.Sublevel open stope method is mostly used to dig up mine in slant middle thick orebody, sublevel open stope method needs cloth when digging up mine
Set and largely adopt quasi- engineering, due to Medium Thickness And Medium Slope Angle blind orebody move towards extend it is smaller, tendency extend it is shorter, these adopt quasi- engineering can not
Recycling increases opening of mines cost often using primary just ineffective.It is a kind of suitable for inclining it is therefore desirable to find
The mining methods of thick blind orebody in tiltedly.
Summary of the invention
Object of the present invention is to propose a kind of Medium Thickness And Medium Slope Angle blind orebody exploitation side to reduce mining cost, improving mining efficiency
Method.
The technical scheme is that a kind of Medium Thickness And Medium Slope Angle blind orebody recovery method, it is small that this method is suitable for strike length
The firm Medium Thickness And Medium Slope Angle blind orebody of 50m, upper lower burrs country rock is extended less than in 100m, tendency, its technical solution is as follows:
A structural parameters: when finding such ore body, the orebody trend length is confirmed through mine locating, buried depth depth, extends depth, shape
After shape, inclination angle, thickness, entire ore body is considered as a nugget, a height of ore body overall height of nugget, nugget width is orebody trend length,
Not pillar in nugget；
B adopts quasi- cutting engineering: tunneling ore removal crosscut to ore body bottom every 5~10m by haulage drift first, opens in ore body bottom
Excavate mine moat ditch；The blind inclined shaft of people's row rock drilling, the blind inclined shaft connection return air of people's row rock drilling are tunneled at the outer 3~8m of ore body lower wall ore-rock boundary
Lane；Track is set in people's row rock drilling blind inclined shaft, hoist engine is set in air return lane, rail cage is controlled by wirerope by hoist engine
In moving up and down for people's blind inclined shaft of row rock drilling；
C back production ore removal engineering: worker bores layering chisel fanhole(s) in rail cage into ore body, and layering explosion layering chisel is fan-shaped
Blasthole, broken ore are transported through ore removal crosscut from haulage drift by scraper from ore removal moat ditch.
It is mixed into further save explosive consumption, reduce barren rock, and in order to protect the blind inclined shaft of people's row rock drilling not to be destroyed,
When layering chisel fanhole(s) powder charge, only to blasthole section powder charge in ore body, blasthole section not powder charge in country rock.
The beneficial effects of the present invention are: this method is by the lifting of cage in the blind inclined shaft of people's row rock drilling instead of sublevel open stoping
Method largely adopts quasi- engineering when digging up mine, and saves and adopts quasi- project inputs, while having many advantages, such as simple process, high-efficient.
Detailed description of the invention

Appended drawing reference in figure: 1- haulage drift, 2- ore removal crosscut, 3- ore removal moat ditch, the blind inclined shaft of 4- people's row rock drilling, 5- air return lane,
6- track, 7- hoist engine, 8- wirerope, 9- rail cage, 10- layering chisel fanhole(s), 11- broken ore.
Specific embodiment
Baiyin's Deep Copper Mine is Large-scale Copper bed famous at one, often there is fragmentary blind squat in mineral deposit by mother-lode
Exposure.Deep Copper Mine mother-lode uses sublevel caving method without sill pillar, and blind orebody uses sublevel open stope method.Sublevel open stope method is being exploited
It needs to tunnel when the outlying blind orebody of the mine largely to adopt quasi- engineering, increases mining cost.Therefore, the mine is in western exploiting field
A kind of Medium Thickness And Medium Slope Angle blind orebody recovery method of the present invention is tested in the exploitation of the middle section 1785m 9# blind orebody.In conjunction with attached drawing,
This method is described in detail:
A structural parameters: it is directed to 9# blind orebody, 45 ° of 9# blind orebody inclination angle, orebody thickness 8m, ore body height 30m, when exploitation will be whole
A 9# blind orebody is considered as a nugget, a height of ore body overall height 30m of nugget, and nugget width is orebody trend length 80m, does not stay in nugget
Ore pillar.
B adopts quasi- cutting engineering: tunneling ore removal crosscut 2 to 9# blind orebody bottom every 5m by 1785m level haulage tunnel 1 first
Portion；By ore removal crosscut 2 9# blind orebody bottom dig ore removal moat ditch 3,45 ° of angle of ore removal moat ditch；9# blind orebody lower wall ore-rock circle
It limits and tunnels the blind inclined shaft 4 of people's row rock drilling at outer 8m, the blind inclined shaft 4 of people's row rock drilling is 43m long, 45 ° of inclination angle, and is segmented air return lane 5 with 1785m
Connection；Track 6 is set in people's row rock drilling blind inclined shaft 4, hoist engine 7 is set in 1785m segmentation air return lane 5, steel is passed through by hoist engine 7
Cord 8 controls the moving up and down in people's blind inclined shaft 4 of row rock drilling of rail cage 9.
C back production ore removal engineering: people, which bores in rail cage 9 into 9# blind orebody, is layered chisel fanhole(s) 10, and hole depth 16 ~
25m, layering explosion layering chisel fanhole(s) 10, broken ore 11 by scraper from ore removal moat ditch 3 through ore removal crosscut 2 from transportation roadway
Road 1 transports.
Further to save material cost, when layering chisel 10 powder charge of fanhole(s), only to blasthole section powder charge in 9# blind orebody,
Blasthole section not powder charge in country rock, processing not only ensure that demolition effect in this way, but also save explosive consumption.
