Description
Technical field
This utility model relates to Application in mining technical field, particularly relates to a kind of mining drop shaft material position automatic measuring system.
Background technology
Non-coal mine underground mining needs the Ore by different mining level blasting excavations to transfer to ore removal level by drop shaft,
Earth's surface is risen to horizontally through elevator etc. again by ore removal.Drop shaft is typically connected as the two or several stage as rolling ore deposit rock
The vertical or pit shaft that tilts, be used in mining, drop shaft could also say that courtyard.Owing to low mine is the highest
Mining depth is very deep, and Ore transports frequently, cost-effective for improving transport efficiency, can get through one from top to bottom and be similar to
The pipeline of vertical shaft, there are V-arrangement poly-ore deposit groove or funnel in bottom, the most directly topple over Ore, and Ore is gone out by poly-ore deposit groove or funnel
Mouthful fall ore removal level, Ore put down after by scraper scraper to vertical shaft ore skip, rail/trackless (electric) locomotive,
Fortune ore deposit truck etc. is transported to earth's surface.On the one hand drop shaft can improve transport efficiency, on the other hand, owing to being directly vertically to incline
Fall (in the case of vertical drop shaft), utilize height, certain powder ore effect can be played.
Courtyard (including drop shaft) is mainly used in slipping ore deposit, pedestrian, haul, ventilation, filling, mine locating etc. (see mine well
Lane).Section is circular (diameter is generally 1.2～2m), square or rectangle (section be 1.5m × 1.5m～
2.5m × 2.5m), the most general ten a few to tens of rice, rice the most up to a hundred.
Along with the progress of mining production automatic technology, in mining production to the demand of drop shaft material position automatic measuring increasingly
Many, currently existing scheme, based on the non-contact measurement such as radar levelmeter, laser range finder, needs the difficult problem bag solved
Include: 1, the drop shaft degree of depth is deeper, it is desirable to have enough sensors of range；2, a large amount of dust, steam can be produced during ore drawing
Deng, disperse, in the air of drop shaft, affects range and the precision of sensor measurement；3, pass is long tubular structure,
The radar wave of noncontacting proximity sensor or laser beam etc. need the least angle of scattering, and otherwise radar wave or laser beam hit and slip
Well sidewall affects certainty of measurement or cannot measure at all.As a example by radar levelmeter, at drop shaft alignment installed above drop shaft
Radar levelmeter, hits, by radar microwave, the tellurometer survey that the Ore that heap bottom drop shaft falls reflects, and inverse slips whereby
The degree of depth of well material position, radar microwave frequency range is 5.8GHz～26GHz, has the advantage that the anti-dust of diffraction is effective,
But typically using 4 " the typical field angle of the 26GHz radar of electromagnetic horn is 8 °, and the typical field angle of 5.8GHz is
17 °, by the drop shaft of diameter 2 meters, use 4 " calculate as a example by the 26GHz radar of electromagnetic horn, its radar wave does not hit drop shaft
Sidewall the most effective measuring section degree of depth maximum is only 14.3 meters, and this creates impact to sensor instrument distance value, the deepest drop shaft
If do not taked ancillary method, radar levelmeter is used to measure difficulty bigger；Drop shaft level gauging is done for laser range finder,
Its advantage is that range finding is remote and angle of scattering is the least, and precision is high, and shortcoming is that laser passes dust ability, and laser lens is easy
Attachment steam and dust, impact is measured, and uses under drop shaft environment, and the suitability and reliability are poor, and needs are artificial constantly
Intervene and measure (clean camera lens, dust removal by ventilation etc.), use in mine less at present, on a small quantity system using effect
Not good enough, it is impossible to meet the demand that mine efficiently produces.
More troublesome, it is that the lump ore preventing explosion from producing transfers the poly-ore deposit blocking drop shaft outlet during part mining production
Groove or funnel, drop shaft fall one grid of mine mouth (drop shaft top opening) upper cover, lump ore can by grid block cannot under
Put, fetch at drop shaft mouth and again transferred after second-time breakage by card lump ore.But grid can be to radar thing in this case
The radar wave of position meter causes and blocks, and measurement cannot be carried out；Although the laser beam of laser range finder can pass grid hole,
But its still suffer from there is no grid in the case of the problem such as that anti-dust weak effect, it is impossible to effectively measure.
It addition, also have the level gauging scheme of guided wave formula on market, it is to utilize guiding microwave radar technology to provide continuous print non-
Machinery level gauging, by electromagnetic wave at whiplike guided wave Propagation, behind contacting material surface, reflection electromagnetic wave, meter
Calculate electromagnetic transmission length and calculate material position；Also have a kind of Weight type scheme, be to utilize draught line to hang a weight to transfer to
Material surface, metering draught line is transferred length and is determined thing position.Both schemes apply existence in drop shaft level gauging
Problem includes: be required for a terminally positioned weight, and when measuring, weight needs contacting material surface, makes at ore storage
Used time, may be blocked by Ore gap and carry to come up, this restrict its use in drop shaft level gauging.
