Description
Technical field
The present invention relates to directed pneumatic shuttle, be generally used for rock or concrete fragmentation, and more particularly, relating to need be with the directed pneumatic shuttle of sand or other sealant backfill.The invention still further relates to a kind of use directed pneumatic shuttle of the present invention and make the method for catalase from surface (mine surface or surface, stone pit).
Background technology
High explosives are widely used in the catalase in quarrying and the mining process, and are used for dismantling operation.Though explosive is effectively, use with regard to its energy, be not effective especially, the restriction that it has danger and therefore is subjected to the relevant specific regulations that it uses, stores and transports.Be used under the situation of dismantling operation at explosive, because the distance that size particles is dispersed by explosive materials, must cleaning demolition point very big zone on every side.Be used in blast process, all employees to be withdrawn whole mine under the situation of underground mining at explosive.And, because the possibility of rockfall, must leave the regular hour preventing blast subsequently, and explosion occurs under the underground situation dangerous gas.
High explosives have the detonation velocity of about per second 6000-9000 rice, and it produces shock wave in rock, thereby with catalase.In some cases, high explosives may limit the degree of depth of the rock that can remove in the onepull event.This be because, if tote is positioned over apart from position too dark below the rock surface, can produce rock fracture, make mine or stone pit dangerous.Under this application, consider that usually the high explosives tote should not be positioned over the following place that surpasses 1.2 meters of this rock surface.
A kind of substitute that replaces explosive to divide rock is directed baric systerm.In this system, boring and directed pneumatic shuttle inserted wherein in rock.This hole is with sand or another kind of suitably sealant backfill.When this device catches fire (rather than blast), can begin chemical reaction, it discharges a large amount of gas.Pressure strengthens in the hole and discharges along with the rock division.The detonation velocity that is used in the pyrotechnics tote in the directed pneumatic shuttle is about 40 meters to 60 meters of per second.These devices can not produce shock wave.So, can make these devices be positioned at the place far away apart from rock surface, thereby allow in the onepull event to remove from the surface relatively large material.
Aspect the amount that discharges the energy that is used for rock division or building demolition, directed baric systerm more produces effect than explosive tote.For example, compare and use the explosive tote, when using this orientation baric systerm, can produce obvious a spot of dust.This has two advantages: one, compare the situation of using the explosive tote, and when using this orientation baric systerm, can more approachingly be broken rock and work.Under the situation in underground mining ore deposit, usually, when explosion took place, whole mine can be eliminated, yet, in the place of using directed baric systerm, can continue to work just approaching in the place of fractured rock.Another advantage of this orientation baric systerm is that tote is more safer than explosive in essence.Classification and rule about its use have reflected this advantage.The another advantage of this system is, its relative high explosives generation noise still less, and can not cause the emission problem of toxic gas.
As mentioned above, this orientation pneumatic shuttle insert in the hole and this hole with sand or the backfill of another kind of appropriate seal agent material.Aspect material, it is cheap coming backfill with sand, but needs labour and a certain amount of sand in the place that rock is pulverized.And the direction that sand can be only be used for the hole is under the situation that horizontal plane tilts, otherwise sand may spill from the hole, in this case, rock will can not be pulverized and should orientation air pressure assembling device will can safety.In addition, the consistency for the sand of filling is vital.For example, may blow sand if sand is too dried or too wet.If the grains of sand are too big or have skimble-scamble shape, also may blow sand.
Can use other backfilling material, but these materials may be expensive.For example, can use the inserts based on resin, even but use these packing materials, still can there are the following problems: when the hole is positioned at horizontal plane when following, be difficult to guarantee under the situation that does not have air bag (for example), fully the hole is filled up.When using resin at that time, may side effect be arranged and cause " explosion (blow out) " subsequently resin sometimes from Residual oil or the water of drilling machine.
A kind of directed pneumatic shuttle of the above-mentioned type is described in No. the 2341917th, the British Patent Application.
International patent application is described a kind of container for pyrotechnical WO2006/063369 number.This invention relates to, and the container of sealing pyrotechnical makes when transportation, compares other locking device, and this container can not be subjected to the restriction of too many strict rule.
Therefore, need provide a kind of directed pneumatic shuttle, its operation does not need backfill.
A kind of catalase cartridge has been described among the US2008/0047455.In described device, tote holds at one end by in the pipe that cap sealed.The middle part of pipe is filled by packing material (such as sand) and the other end is sealed by a pair of wedge shape part.When this device be inserted into will the hole of fragmented rock in the time, one in the wedge shape part is further promoted in the pipe, thereby this device is fixed in the hole.This device can not use when having middle inserts, and in this case, the wedge shape part that is forced to further separate by the air pressure in the device can be fixed on this device in the hole.
Though said apparatus does not need backfill, its use may be subjected to the restriction of low relatively air pressure.This is because this device depends on air pressure and comprised by the wedge shape part.If the wedge shape part lost efficacy, then situation likely is, the air pressure of increase catches fire this device outside the hole.
Mining is usually directed to, and makes material fragmentation on the surface it being picked up, these materials are packed on the means of transport, and with these material delivery to processing factory.As mentioned above, explosive can be used to from the surface failure of rock material, but the use of explosive need empty mine usually.Blast is carried out under the situation that the miner that is everlasting is absent from the scene, for example, and before every morning, the miner started working or during changing shifts.Yet this just means that during miner's changing shifts, wide variety of materials must make that having enough materials allows the miner carry from surface failure of rock relatively.And, between explosion period if may to have unauthorized employee on the scene then be dangerous.
Therefore, need not use explosive and can exploit material.
Sometimes under the situation that does not have blast, implement mining, for example, use machine.CA2060288 number description of patent application is a kind of uses a plurality of cutting blades to cut away the machine of material from the surface.Yet this machine can not be used for all situations, and it requires to lay track and other infrastructure, and very expensive.
Yet, under the situation of using blast, also may be to a certain extent with the blast process automation.For example, a kind of being suitable at material surface boring and vehicle that the explosive tote is inserted in the hole described in patent application W097/21068 number.
A kind of improvement method of mining need be provided, thus, compare the situation of using blast, can be relatively little but more regular from the amount of the material of surface failure of rock.

The specific embodiment
Refer now to Fig. 1 and Fig. 3, directed pneumatic shuttle 1 of the present invention comprise by appropriate hard material (such as, polypropylene or polyurethane) outer tube 2 that forms.Interior pipe 3 is positioned at outer tube 2 with one heart.The pyrotechnic material 4 that discharges gas when the space of formation is by unlatching between outer tube 2 and interior pipe 3 is filled.The main gas that discharges is carbon dioxide and carbon monoxide.Normally, pyrotechnic material is lighted by electric initiating.The external diameter of the internal diameter of interior pipe and pull bar 5 is consistent substantially, and the interior diameter of pipe 3 made bar 5 to slide in interior pipe 3 in the diameter of pull bar 5 was slightly less than.The wall of outer tube 2 and interior pipe 3 is preferably between between the 0.5mm to 1.0mm.
There is screw thread 6,6 ' at each place, end at bar 5.After placing in interior pipe 3, the end of pipe 3 and outer tube 2 in the end of thread 6,6 ' stretches out makes pipe closure member 7,7 ' can be attached to the end of thread.
Fig. 5 illustrates one of the present invention and replaces embodiment, and wherein, the lug 11 of closure member 7 constitutes whole (for example, by molded appropriate plastic material) with pull bar 5.Referring to figs. 1 to Fig. 3 closure member 7 ' is described.
Fig. 6 and Fig. 7 illustrate another embodiment of the invention, and wherein, closure member 7,7 ' comprises 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 by the new embodiment of Fig. 6 center line A-A intercepting, and Fig. 7 b illustrates closure member 7,7 ' enlarged drawing.In this embodiment, pipe 3 in not having, and wedge shape part 10,10 ' with aforementioned embodiments in the wedge shape part compare and have different structures.New wedge shape part 10,10 ' cross section and perspective view are shown respectively among Fig. 7 b and Fig. 8.As seen, wedge shape part 10,10 ' is conical butt, to replenish taper lug 11,11 ' and comprise slit 27 along the part of its length, so that tender spots to be provided.These points help to guarantee that wedge shape part 10,10 ' end are pushed in the wall in hole 23 at explosion time.Slit 27 in the degree of depth at wedge shape part 10,10 ' outer surface 28 places less than the degree of depth of slit 27 at wedge shape part 10,10 ' inner surface 29 places.In Fig. 6 and embodiment illustrated in fig. 7, the plastic material of similar hardness forms by having roughly for wedge shape part 10,10 ', closure member 7,7 ', pull bar 5 and lug 11,11 '.
With reference now to Fig. 4,, shows mining surface 20.Use directed pneumatic shuttle of the present invention with from surperficial crushed rock, in rock, get out a plurality of holes 23.Then will install in 1 patchhole 23.Yet, before blast, must be at the mining angled slit of surface cut place (directly closing on top 21 and the bottom 22 of mine) to guarantee cleaning, even pulverize.Before in will installing 1 patchhole 23, lug 11,11 ' is suitably strained.Then opening device 1 makes that surface 20 is cracked, causes the block of rock 24 to scatter from the surface.Then fractured rock is transported from the surface of digging up mine by moving towards ditch (strike gully) 26.
For using filler to there is no need with the backfill hole.When device 1 was opened, pyrotechnic material 4 began to discharge gas, thereby increased the pressure in the device 1.This pressure increase causes seal 8,8 ' axially along pull bar 5 towards seal 9,9 ' and wedge shape part 10,10 ' mobile, thereby causes wedge shape part 10,10 ' with identical moving axially.The surface 14 of corresponding inclination, 14 ' and 15,15 ' effect be, causes wedge shape part 10,10 ' outwards mobile to engage the wall that this installs the hole at 1 place, then with the hole sealing, thereby gas-pressurized is limited in part in this hole, device place.The hole 23 drilled nominal diameters that go out to have 1mm, 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 to move reaching 5mm, thereby guarantee that the wedge shape part engages with the wall in hole 23, even have in hole wall under the situation of surface irregularity.Thereby device 1 is fixed on (at its two ends) in the hole.And, 5 restrictions of air pressure tension member.The power that increase by air pressure produces is enough to the end of wedge shape part is advanced in the inwall in hole 23 usually.
Though there is slit (may overflow by this slit gas) in open wedge shape part, this can't injure the validity of device significantly.This is existed many reasons.In comprising seal 8,8 ' embodiment, seal 8,8 ' can be by than seal 9,9 ' and 10,10 ' the softer plastic material forms, and the increase of device internal gas pressure causes these seals 8,8 ' distortion, and this distortion comprises that seal 8,8 ' thickness reduce to increase with diameter.Therefore, seal 8,8 ' peripheral wall begin to engage with the wall in hole 22.In addition, when pyrotechnic material 4 discharges gas, follow significant heat to discharge, it is plastic that this heat is enough to make hard plastics to become, and seals with the wall of relative opening 22 thereby expand.And by open wedge spare 10, the 10 ' pipeline that presents is relatively little and do not allow gas at full speed to overflow, and is 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.The pyrotechnics tote can cause seal 9,9 ' distortion, to seal this device.
The result who produces is the same with other directed pneumatic shuttles, and for example, rock is broken.Yet, do not need filler.This just means that this orientation pneumatic shuttle 1 can be used in the application of the pneumatic shuttle that can not use prior art.In addition, in all application, because the fireman does not need to carry filler, not needing with filler backfill hole, or do not need for essential tool is carried in the filler backfill, is simple so use the method for this device.
The present invention also provides a kind of improvement method of mining, and wherein, 3 groups of personnel cooperate with each other.With reference to 4, the first groups of personnel's borings of figure, device of the present invention is inserted in the hole again.Second group of personnel uses directed pneumatic shuttle crushed rock of the present invention, and the 3rd group of personnel cleaning fractured rock after second group of personnel's work is finished.This advantage that has is that mining almost becomes continuous process, wherein, almost do not have catalase to leave the slit, and this rock is eliminated substantially before next catalase is left the slit.Make mining process continuous as much as possible, normally more effective.If enough materials of having to explode cooperate (occupy) labour for an integral body changing shifts, this may exist its own logistics (logistic, logic) difficulty.
