Description
Anordning for fylling av partikkelformet sprengstoff i hull boret i fjell. Device for filling particulate explosives into holes drilled in rock.
Oppfinnelsen vedrører en anordning for fylling av pulver- eller kornformet The invention relates to a device for filling powder or granule form
sprengstoff i hull boret i fjell, idet sprengstoffet føres av et trykkmedium, som f. eks. trykkluft, gjennom et lader ør inn i hullet. Dette laderør, som kan ha form av en bøyelig slange, har mindre diameter enn hullet. Det er kjent å oppsamle sprengstoff som følger med returstrømmen av trykkmediet i mellomrommet mellom røret og hullet. En tetning anbringes da omkring røret ved hullets munning, og fra denne tetning utgår et annet rør til en se-parator for det medførte sprengstoff. Denne kjente konstruksjon er imidlertid rela-tivt komplisert i bruk. Oppfinnelsen tar sikte på å tilveiebringe en anordning som forenkler arbeidet og tillater en langt dre-vet separering av tilbakestrømmende explosives in holes drilled in rock, as the explosives are carried by a pressure medium, such as e.g. compressed air, through a charger ear into the hole. This charging tube, which may take the form of a flexible hose, has a smaller diameter than the hole. It is known to collect explosives that accompany the return flow of the pressure medium in the space between the pipe and the hole. A seal is then placed around the pipe at the mouth of the hole, and from this seal another pipe leads to a separator for the entrained explosives. However, this known construction is relatively complicated to use. The invention aims to provide a device which simplifies the work and allows a far-driven separation of the backflowing
sprengstoffpartikler, samtidig som rørene er lett manøvrerbare. Oppfinnelsen kjen-netegnes i det vesentlige ved at der på rø-rets utside anbringes et gitterverk eller filter som er utformet for å tillate passasje av det tilbakestrømmende trykkmedium mellom røret og hullveggen, men samler opp medførte partikler. explosive particles, while the pipes are easily manoeuvrable. The invention is essentially characterized by the fact that a grating or filter is placed on the outside of the pipe, which is designed to allow passage of the backflowing pressure medium between the pipe and the hole wall, but collects entrained particles.

I fig. 1 betegner 10 et i fjellet utboret hull som skal fylles med sprengstoff. I hullet innføres et rør, fortrinnsvis i form av en bøyelig slange 12, som står i forbin-delse med en kilde for et trykkmedium, fortrinnsvis trykkluft, og fortrinnsvis også med en forrådsbeholder for sprengstoffet In fig. 1 denotes 10 a hole drilled in the rock to be filled with explosives. A tube is introduced into the hole, preferably in the form of a flexible hose 12, which is in connection with a source for a pressure medium, preferably compressed air, and preferably also with a storage container for the explosive
(ikke vist). Sprengstoffet utgjøres av korn, (not shown). The explosive consists of grain,
resp. pulver, som f. eks. ammoniumnitrat, og er vanligvis blandet med en mindre mengde olje, hvorved massen til en viss grad blir klebrig. Sprengstoffet avsetter seg i hullet mens slangen 12 trekkes til-bake. Den luft som er nødvendig for tran-sporten avgår i mellomrommet mellom hullet og slangen. Ifølge oppfinnelsen er der nu omkring slangen 12 anbragt et slags gitterverk eller filter som slipper igjennom returluften, men som samtidig tilbakehol-der sprengstoffpartiklene og hindrer dem respectively powder, such as ammonium nitrate, and is usually mixed with a small amount of oil, whereby the mass becomes sticky to a certain extent. The explosive settles in the hole while the hose 12 is pulled back. The air required for the transport leaves in the space between the hole and the hose. According to the invention, a kind of grating or filter is now placed around the hose 12 which allows the return air to pass through, but which at the same time retains the explosive particles and prevents them
fra å rives med og transporteres med luften ut av hullet. from being swept along and transported with the air out of the hole.
Ved utførelsesformen ifølge fig. 1 er In the embodiment according to fig. 1 is
der på utsiden av slangen 12, og på en mindre avstand fra dens i hullet 10 belig- there on the outside of the hose 12, and at a smaller distance from it in the hole 10 belig-
gende avløpsende, anbragt en krans av tråder eller strå 14, hvilke er festet ved hjelp av en ring 16, og som fortrinnsvis forløper skrått stråleformet utad. Trådene eller stråene 14 kan være anordnet i ett eller flere børstelag som er dreiet noe spiralformet. Disse er fortrinnsvis av ikke-metallisk materiale, som f. eks. piasava, leading to the drain end, placed a garland of threads or straws 14, which are attached by means of a ring 16, and which preferably extend obliquely outwards in a beam shape. The threads or straws 14 can be arranged in one or more brush layers which are turned somewhat spirally. These are preferably of non-metallic material, such as e.g. piasava,
plast eller lignende. Det vesentlige er at de har en slik innbyrdes deling at de oppfanger sprengstoffpartikler som følger med returluften mellom slangen og hullveggen, plastic or similar. The essential thing is that they have such a separation between them that they catch explosive particles that come with the return air between the hose and the hole wall,

Av-setningene kan fra tid til annen fjernes, grains thus deposited on the brush formed by the threads can further improve the intended filter effect. The disclaimers may be removed from time to time,
enten utenfor eller i berghullet, i hvilket sistnevnte tilfelle de direkte anvendes for hullets fylling. either outside or in the rock hole, in which latter case they are directly used for filling the hole.
Trådene eller børstene 14 strekker seg The wires or brushes 14 extend
fra innfestningsstedet i ringen 16 skrått fremover mot slangens avløpsende, og er til en viss grad elastiske. For å lette børstenes innføring i borhullet, kan de omsluttes av en hette 18 av plast eller lignende, hvilken hette automatisk trekkes av i og med at trykkluften slippes gjennom slangen. from the attachment point in the ring 16 obliquely forward towards the drain end of the hose, and are elastic to a certain extent. To facilitate the introduction of the brushes into the drill hole, they can be enclosed by a cap 18 made of plastic or the like, which cap is automatically pulled off as the compressed air is released through the hose.
Ved utførelsesformen ifølge fig. 3 er In the embodiment according to fig. 3 is
der på en hylse 20 anordnet pigger 22 eller lignende, hvilke pigger forløper radialt, where spikes 22 or the like are arranged on a sleeve 20, which spikes extend radially,
eller stort sett radialt, utover. Piggene er fortrinnsvis anordnet i flere lag, hvilke lag er innbyrdes periferielt forskjøvet, slik at direkte passasjer for returluften ikke forefinnes. Piggene 22, hvilke er beregnet for å spenne over mellomrommet mellom slangen og hullveggen, kan være utført i ett med hylsen 20, f. eks. ved å støpes i plast sammen med denne. Hylsen er på- or mostly radially, outwards. The spikes are preferably arranged in several layers, which layers are mutually circumferentially offset, so that there are no direct passages for the return air. The spikes 22, which are designed to span the space between the hose and the hole wall, can be made integral with the sleeve 20, e.g. by being cast in plastic together with this. The sleeve is on-

Ved utførelsesformen ifølge fig. 4 er tråder 24 av elastisk, ikke-metallisk mate- In the embodiment according to fig. 4 are strands 24 of elastic, non-metallic mate-

The granular explosive is carried by the air flow out of the hose, and the return air is filtered by passage of the outer and/or the inner wire ring.

Oppfinnelsen er ikke begrenset til de over into the borehole 10, the flanges 38 being bent backwards. In fig. 7, on the other hand, it is assumed that charging of the borehole with explosives is in progress, while the hose is pulled backwards out of it. The invention is not limited to those
