Abstract
The utility model provides a mining system is synthesized by gradual anxious shallow bore hole to extremely thin complicated quartz reef, include vent ( -escape) raise, funnel neck, by the way false well, draw the end, scraper chamber no. 1 and scraper chamber no. 2, funnel neck and draw the secondary cutting in end tunnel, the false well of direct route that personnel, material and equipment pass through the stope both ends gets into the stope. Do you adopt YT along the mineral building direction of height during back production 28 and YSP 45 rig chisel up -hole to the vent ( -escape) raise for the blasting scope of freedom toward the drawing back of stope both ends, carry out local ore drawing after the blasting at every turn, emit promptly and explode 60% and 40% of ore down, with this circulation, finish until mineral building blasting back production in the back production rock drilling space of ensureing 1.6~1.8 BRATs behind the flat field, carries out finally ore drawings in a large number at last. The mining of this system of adoption, the ore block rate of extraction is high, has very strong reference and promotes the meaning the extremely thin complicated quartz reef of mine of the same type back production.
Description
Technical field
This utility model relates to a kind of very thin complicated quartz reef by the gradual comprehensive mining system of anxious shallow bore hole, particularly belongs to adopt
Ore deposit technical field.
Background technology
Being breasting method below 50 ° for dip angle, dip angle uses shrinkage method for more than 50 °, and in the past for ore deposit
Arteries and veins inclination angle is by gradual anxious complicated mineral ore back production, and that takes remains single breast stoping, for this complicated mineral ore, adopts
There is many defects: being first that the back production difficulty of pitching vein is relatively big after change, stope two ends are difficult to single mining system
Form passage, owing to there is no polycrystalline substance, more difficult control during scraper rake ore deposit, add stope flat field, ore drawing work difficulty, and
Block stoping rate is low, and cost is high.Next to that mining efficiency is low, potential safety hazard is relatively big, and resource can not get fully reclaiming.This practicality is new
Type proposes a kind of comprehensive mining system, and mineral ore, by changing original engineering way after gradual urgency, carries out shrinkage method stope in mineral building
Polycrystalline substance secondary cut, including filler neck, by the way false well and undercut, the filler neck after secondary cut does not install funnel,
The most false well enters the scope of operation from mineral building two ends for personnel, material and equipment, and worker stands uses YSP-45 shallow on the ore deposit heap of avalanche
Drilling machine carries out rock drilling, because having increased mineral building polycrystalline substance newly, operating personnel's security reliability is greatly improved, thus improves mining
Efficiency and block stoping rate.

Detailed description of the invention
Embodiment
A kind of very thin complicated quartz reef of this utility model is by gradual anxious shallow bore hole comprehensive mining system specific implementation process such as
Under, detailed description of the invention sees figures.1.and.2.
, ore body is divided mineral buildings with 45 meters of length, reserved studding (13) (14), fore-set (21), foundation one (7) in mineral building
With foundation two (19)；
B, in the middle part of mineral building, tunneling ventilation courtyard (2) runs through the stage casing, top (22) that drift is corresponding；
C, in mineral building drift (1) every 7m upwards dig height the filler neck one (3) of 3m, filler neck two (4), funnel
Neck three (5), filler neck four (6), then undercut to the mineral building other end in the People's Bank of China's connecting taxiway (8) terminating stope, draw
End height is 1.8m, the high 3m of foundation one (7), runs through western studding (14) as passing in and out first extra exit (9) of stope the most also
Double as scraper chamber one (9), and utilize filler neck four (6) as stope the second extra exit (6), drive filler neck one
(3), filler neck two (4) is used when installing cement hopper ore drawing, remaining filler neck three (5) and the openning back production of vent (-escape) raise (2) bottom
Mine timber is closed, and prevents Ore avalanche in drive；
D, employing YT-28 bore to tilting big gun hole (20) along mineral building short transverse Drilling, are quick-fried with leading vent (-escape) raise (2)
The broken scope of freedom, from bottom to up in bench to the drawing back of mineral building two ends；Every separate explosion length lengthens with the increasing on the scope of freedom,
After every separate explosion terminates, watering of first ventilating, check mineral building top board and highwall, process Pumex, then use the scraper of power 28KW
Carrying out local ore drawing, after releasing the 60% of each broken ore, start smooth location, after flat field, stoping operation face keeps 1.7m high
Space is to meet rock drilling requirement；The direct route vacation well one (12) at mineral building two ends mine timber plank carries out supporting, and has set up People's Bank of China's ladder
Son；Along with the rising of back production height, mineral building top board exposed area incrementally increases, and will reserve safety pillar (11) in time；With this
Circulation until back production to mineral ore by gradual urgency；
E, at mineral building mineral ore by gradual anxious across pitch with 3m for interval, upwards dig the high secondary cut filler neck (18) of 3m
Totally 4, and in direct route vacation well (17) high for mineral building two ends driving 5m, undercut to mineral building center in the most false well (17),
Undercut height 1.8m, and foundation two (19) height is 3m, has dug scraper chamber two (15), and at secondary cut filler neck (18) totally 4
Individual funnel eck, towards the position of mineral building top board down about 2m, makes a call to 8～10 scraper calabash awns bar (23) eyes along run, for
Follow-up mineral building rake ore deposit is ready；After secondary cut filler neck (18) and the cutting that undercuts complete, secondary cut filler neck
(18) totally 4 funnel is not the most installed；Direct route vacation well (17) from mineral building two ends of personnel, material and equipment enters the scope of operation；Back production
Use YSP-45 bore stamp to tilt big gun hole (20), with vent (-escape) raise (2) be the explosion scope of freedom toward the drawing back of mineral building two ends,
Every separate explosion laggard row local ore drawing, uses scraper to release the 40% of each broken ore, check after local ore drawing mineral building top board and
Country rock helped by mineral building two, processes Pumex, smooth location, checks for cavity, carries out the second-time breakage of bulk in mineral building in time, finds
Cavity immediately treats；The circulation of next explosion stoping operation is entered, directly after keeping 1.8～2.0m high back production rock drilling spaces after flat field
Terminate to mineral building explosion back production；
F, mineral building explosion are all released remaining Ore in stope after terminating, and use two scraper relay rake ore deposits to turn through funnel
It is transported to mine car.
