Description
Technical field
The present invention relates to directed pneumatic shuttle, be generally used for rock or concrete fragmentation, and more particularly, relate to the directed pneumatic shuttle do not needed with sand or the backfill of other sealant.The invention still further relates to a kind of use directed pneumatic shuttle of the present invention makes catalase method from surface (mining surface or surface, stone pit).
Background technology
High explosives are widely used in the catalase in quarrying and mining process, and for dismantling operation.Although explosive is effective, using with regard to its energy, is not effective especially, and it has danger and is therefore subject to the restriction about its specific regulations using, store and transport.When explosive is used for dismantling operation, due to the distance that size particles is dispersed by explosive materials, the very large regions around demolition point must be cleared up.When explosive is used for underground mining, in blast process, all employees must be withdrawn whole mine.And, due to the possibility of rockfall, the regular hour must be left to prevent blast subsequently, and when explosion occurs in underground, dangerous gas.
High explosives have the detonation velocity of about 6000-9000 rice per second, and it produces shock wave in rock, thus by catalase.In some cases, high explosives may limit the degree of depth of the rock can removed in onepull event.If this is because, tote is positioned over the too dark position of below distance rock surface, can rock fracture be produced, make mine or stone pit dangerous.Under this application, usually consider that high explosives tote should not be positioned over the place of below this rock surface more than 1.2 meters.
A kind of substitute replacing explosive to divide rock is directed baric systerm.In such a system, hole in rock and directed pneumatic shuttle is inserted wherein.This hole is with sand or the backfill of another kind of suitably sealant.When this device catches fire (instead of blast), can start chemical reaction, it discharges a large amount of gas.Pressure strengthens and discharges along with rock division in hole.The detonation velocity being used in the pyrotechnics tote in directed pneumatic shuttle is about 40 meters to 60 meters per second.These devices can not produce shock wave.So, these devices can be made to be positioned at distance rock surface place far away, thus to allow to remove relatively large material from surface in onepull event.
In the amount discharging the energy being used for rock division or building demolition, directed baric systerm is more effective than explosive tote.Such as, comparing and use explosive tote, when using this directed baric systerm, obviously a small amount of dust can be produced.This has two advantages: one, compares the situation using explosive tote, when using this directed baric systerm, and can closer to being broken rock and working.When underground mining ore deposit, usually, when explosion occurs, whole mine can be eliminated, but, using the place of directed baric systerm, can continue just to work in the place of fractured rock comparatively close.Another advantage of this directed baric systerm is that tote is more safer than explosive in essence.The classification used about it and rule reflect this advantage.The another advantage of this system is, its relative high explosives produce less noise, and can not cause the emission problem of toxic gas.
As mentioned above, this directed pneumatic shuttle insert in the hole and this hole with sand or another kind of appropriate seal agent material backfill.In material, it is cheap for backfilling with sand, but needs labour and a certain amount of sand in the place that rock is pulverized.And when sand can only tilt for the direction in hole in the horizontal plane, otherwise sand may spill from hole, and in this case, rock can not be pulverized and this directed air pressure assembling device can not safety.In addition, the consistency for the sand of filling is vital.Such as, if sand is too dry or too wet, may blow sand.If the grains of sand are too large or have skimble-scamble shape, also may blow sand.
Can use other backfilling material, but these materials may be expensive.Such as, the inserts based on resin can be used, even if but use these packing materials, or can there are the following problems: when hole is positioned at below horizontal plane, be difficult to ensure, when there is no air bag (such as), fully hole to be filled up.When using resin at that time, sometimes may there is side effect to resin from the Residual oil of drilling machine or water and cause subsequently " explosion (blow out) ".
A kind of directed pneumatic shuttle of the above-mentioned type is described in No. 2341917th, UK Patent Application.
No. WO2006/063369th, international patent application describes a kind of container for pyrotechnical.This invention relates to, and closes the container of pyrotechnical, makes, when transporting, to compare other locking device, and this container can not by the restriction of too many strict rule.
Therefore, need to provide a kind of directed pneumatic shuttle, its operation does not need backfill.
A kind of catalase cartridge is described in US2008/0047455.In described device, tote be contained in one end by cap in the pipe closed.The middle part of pipe filled by packing material (such as sand) and the other end by a pair wedge shape part close.When this device be inserted into will in the hole of fragmented rock time, one in wedge shape part is further promoted in pipe, thus is fixed in hole by this device.This device can use when not having central filler material, and in this case, this device can be fixed in hole by the wedge shape part being forced to by the air pressure in device be separated further.
Although said apparatus does not need backfill, its use may be subject to the restriction of relatively low air pressure.This is because this device depends on air pressure and is comprised by wedge shape part.If wedge shape part lost efficacy, then situation likely was, the air pressure of increase makes this device catch fire outside hole.
Mining is usually directed to, and makes material fragmentation to be picked up on surface, is loaded on means of transport by these materials, and by these material delivery to processing factory.As mentioned above, explosive can be used to from surface failure of rock material, but the use of explosive needs to empty mine usually.Blast is carried out, such as, before every morning, miner started working or during changing shifts through the miner that is everlasting is absent from the scene when.But this just means, during miner's changing shifts, relatively a large amount of materials from surface failure of rock, must make to have enough materials and allows miner carry.And, if unauthorized employee may be had between explosion period on the scene, be dangerous.
Therefore, need not use explosive and can mined material.
Sometimes implementing mining when not exploding, such as, using machine.No. CA2060288th, patent application description is a kind of uses multiple cutting blade to cut away the machine of material from surface.But this machine can not be used for all situations, it requires to lay track and other infrastructure, and very expensive.
But, when using blast, also may to a certain extent by blast process automation.Such as, No. W097/21068th, patent application describes a kind of being suitable in material surface boring and the vehicle inserted in the hole by explosive tote.
Need the ameliorative way that a kind of mining is provided, thus, compare the situation using blast, can be relatively little but more regular from the amount of the material of surface failure of rock.

Detailed description of the invention
Refer now to Fig. 1 and Fig. 3, directed pneumatic shuttle 1 of the present invention comprises the outer tube 2 formed by appropriate hard material (such as, polypropylene or polyurethane).Interior pipe 3 is positioned at outer tube 2 with one heart.The space formed between outer tube 2 and interior pipe 3 is filled by the pyrotechnic material 4 discharging gas when opening.The predominant gas discharged is carbon dioxide and carbon monoxide.Normally, pyrotechnic material is lighted by electric initiating.The internal diameter of interior pipe is consistent substantially with the external diameter of pull bar 5, and the diameter of pull bar 5 is slightly less than the interior diameter of interior pipe 3, and bar 5 can be slided in interior pipe 3.The wall of outer tube 2 and interior pipe 3 is preferably between 0.5mm to 1.0mm.
Screw thread 6,6 ' is had in each end of bar 5.After placing in interior pipe 3, the end of thread 6,6 ' stretches out the end of interior pipe 3 and outer tube 2, makes pipe closure member 7,7 ' to be attached to the end of thread.
Pipe closure member 7,7 ' comprise seal 8,8 ' and 9,9 ', wedge shape part 10,10 ' and lug 11,11 '.Lug 11,11 ' comprises internal thread hole.Seal 8,8 ' and 9,9 ' comprises Centered hole, and the diameter in hole is corresponding to the overall diameter of pipe 3 interior in seal 8,8 ' situation and the overall diameter of seal 9,9 ' situation lower link 5.During assembling, seal 8,8 ' adapts in the end of body, makes to depend on seal, and the collar 12,12 ' adapts between interior pipe 2 and outer tube 3.Seal 9,9 ' lays respectively on the surface of the collar 12,12 '.The collar comprises and is multiplely positioned at lug 11, wedge shape part 10,10 ' between 11 ' and seal 9,9 '.The inner surface 15,15 ' of wedge shape part 10,10 ' is towards the inclination of the longitudinal axis of this device.The surface 14 of lug 11,11 ', 14 ' and the surface 15,15 ' of wedge shape part 10,10 ' roughly tilt with angle.So along with the contact on surface 14,14 ' and surperficial 15,15 ', any motion towards lug 11,11 ' of wedge shape part 10,10 ' causes the outwards movement of described wedge shape part.
Fig. 5 illustrates that one of the present invention is replaced embodiment, and wherein, lug 11 and the pull bar 5 of closure member 7 form entirety (such as, by molded suitable plastic material).Referring to figs. 1 to Fig. 3, closure member 7 ' is described.
Fig. 6 and Fig. 7 illustrates another embodiment of the invention, wherein, closure member 7,7 ' comprise seal 8,8 ', wedge shape part 10,10 ' and lug 11,11 ', but do not comprise the seal 9,9 ' of aforementioned embodiments.Fig. 6 illustrates the plane of new embodiment, and Fig. 7 a illustrates the cross section of the new embodiment by Fig. 6 taken along line A-A, and Fig. 7 b illustrates the enlarged drawing of closure member 7,7 '.In this embodiment, there is no interior pipe 3, and wedge shape part 10,10 ' has different structures compared with the wedge shape part in aforementioned embodiments.Cross section and the perspective view of new wedge shape part 10,10 ' are shown in Fig. 7 b and Fig. 8 respectively.As visible, wedge shape part 10,10 ' is conical butt, with supplementary taper lug 11,11 ' and part along its length comprises slit 27, to provide tender spots.These points contribute to guaranteeing that the end of wedge shape part 10,10 ' is pushed in the wall in hole 23 at explosion time.Slit 27 is less than the degree of depth of slit 27 at inner surface 29 place of wedge shape part 10,10 ' in the degree of depth at outer surface 28 place of wedge shape part 10,10 '.In Fig. 6 and embodiment illustrated in fig. 7, wedge shape part 10,10 ', closure member 7,7 ', pull bar 5 and lug 11,11 ' formed by the plastic material with roughly similar hardness.
With reference now to Fig. 4, show mining surface 20.Use directed pneumatic shuttle of the present invention with from surperficial crushed rock, in rock, get out multiple hole 23.Then by device 1 patchhole 23.But, before blast, must mining the angled slit of surface cut place (directly closing on top 21 and the bottom 22 of mine) to guarantee to clean, even if pulverize.By before in device 1 patchhole 23, lug 11,11 ' is suitably tensioned.Then opening device 1, makes surface 20 cracked, causes the block of rock 24 to scatter from surface.Then fractured rock is transported from mining surface by moving towards ditch (strike gully) 26.
Use filler be there is no need to backfill hole.When device 1 is opened, pyrotechnic material 4 starts to discharge gas, thus increases the pressure in device 1.This pressure increase causes seal 8,8 ' axially to move along pull bar 5 towards seal 9,9 ' and wedge shape part 10,10 ', thus causes wedge shape part 10,10 ' to move axially with identical.The effect on the surface 14,14 ' and 15,15 ' of corresponding inclination is, causes wedge shape part 10,10 ' outwards mobile with the wall in the hole engaging this device 1 place, is then sealed in hole, thus gas-pressurized is limited in the part in this hole, device place.The drilled nominal diameter going out to have 1mm in hole 23, it is greater than the diameter of device 1.The shape of wedge shape part 10 and lug 11 and size cause the end of wedge shape part outwards movement can reach 5mm, thus guarantee that wedge shape part engages with the wall in hole 23, even if when having surface irregularity in hole wall.Thus device 1 is fixed on (at its two ends) in hole.And air pressure tension member 5 limits.The power produced by the increase of air pressure is enough to usually by the inwall of the end advancement holes 23 of wedge shape part.
Although open wedge shape part exists gap (may be overflowed by this gap gas), this can't injure the validity of device significantly.This is existed to many reasons.In the embodiment comprising seal 8,8 ', seal 8,8 ' can by than seal 9,9 ' and 10,10 ' softer plastic material formation, the increase of device internal gas pressure causes these seals 8,8 ' to be out of shape, and the thickness that this distortion comprises seal 8,8 ' reduces and diameter increase.Therefore, the peripheral wall of seal 8,8 ' starts to engage with the wall in hole 22.In addition, when pyrotechnic material 4 discharges gas, with significant Thermal release, this heat is enough to make hard plastics become plastic, thus expansion seals with the wall of relative opening 22.And the pipeline presented by open wedge part 10,10 ' is relatively little and do not allow gas at full speed to overflow, be enough to stop the air pressure in the hole in this device peripheral region obviously to strengthen.As mentioned above, seal 8,8 ' is not necessary for the present invention.Pyrotechnics tote can cause the distortion of seal 9,9 ', to seal this device.
The result produced is the same with other directed pneumatic shuttles, and such as, rock is broken.But, do not need filler.This just means, this directed pneumatic shuttle 1 can be used in the application of the pneumatic shuttle that can not use prior art.In addition, in all applications, because fireman does not need to carry filler, do not need to backfill hole with filler, or do not need for filler backfill is carried essential tool, so use the method for this device to be simple.
Present invention also offers a kind of ameliorative way of mining, wherein, 3 groups of personnel cooperate with each other.Referring again to Fig. 4, a group of people holes, and is inserted in the hole by device of the present invention.Second group of librarian use directed pneumatic shuttle crushed rock of the present invention, and the 3rd group of personnel clear up fractured rock after second group of person works completes.This advantage had is, mining almost becomes continuous print process, wherein, almost do not have catalase to leave gap, and this rock is substantially eliminated before next catalase leaves gap.Make mining process continuous, normally more effective as much as possible.Enough materials that explodes if had in order to an entirety changing shifts coordinate (occupy) labour, and this may also exist its own logistics (logistic, logic) difficulty.
