Description
Fremgangsmåte ved pakking av sprengstoffer med flyteevne. Procedure for packing explosives with buoyancy.
Denne oppfinnelse vedrører en fremgangsmåte ved pakking av sprengstoffer med flyteevne. This invention relates to a method for packing explosives with buoyancy.
Med uttrykket «sprengstoffer med flyteevne» er det ment å betegne sprengstoffer som kan bringes til å «flyte» utover, even-tuelt etter å være utsatt for trykk. Således er uttrykket ment å omfatte også pulver-formete eller tixotrope stoffer. With the expression "explosives with the ability to float" it is intended to denote explosives that can be made to "float" outwards, possibly after being exposed to pressure. Thus, the term is intended to also include powder-shaped or thixotropic substances.
Hensikten med oppfinnelsen er å kom-me frem til en fremgangsmåte ved pakking, The purpose of the invention is to arrive at a method for packaging,
av sprengstoffer, som kan gjennomføres på en effektiv måte og samtidig byr visse fordeler med hensyn til innføringen av sprengstoffet i et borhull. of explosives, which can be carried out in an efficient manner and at the same time offer certain advantages with regard to the introduction of the explosive into a borehole.
Fremgangsmåten ifølge oppfinnelsen The method according to the invention
er kjennetegnet ved at sprengstoffet til-føres til et lengdeveis oppslisset rør som har overlappende slisskanter og er laget av et materiale med så stor elastisitet at sliss-kantene kan føres elastisk bort fra hverandre for' enten å muliggjøre sideveis inn-føring av sprengstoff og/eller hjelpemid-ler for sprengningen, eller ved å sette innholdet under trykk medfører at det flyte-dyktige innhold kan presses sideveis for enten å flyte ut av røret eller å øke rør-diameteren. is characterized by the fact that the explosive is supplied to a longitudinally slotted pipe which has overlapping slot edges and is made of a material with such great elasticity that the slot edges can be moved elastically away from each other to either enable lateral introduction of explosive and/or or aids for the bursting, or by putting the contents under pressure means that the buoyant contents can be pushed sideways to either flow out of the pipe or to increase the pipe diameter.
Ytterligere trekk ved oppfinnelsen vil fremgå av den etterfølgende beskrivelse under henvisning til de medfølgende teg-ninger, hvor: Fig. 1 viser røret som anvendes i fremgangsmåten ifølge oppfinnelsen, i ube-lastet tilstand og. vist i tverrsnitt. Fig. 2. viser røret i tverrsnitt i en f j ær- spent tilstand. Fig. 3 viser røret i tverrsnitt under Further features of the invention will be apparent from the following description with reference to the accompanying drawings, where: Fig. 1 shows the pipe used in the method according to the invention, in an unloaded state and. shown in cross section. Fig. 2 shows the pipe in cross-section in a spring tense state. Fig. 3 shows the pipe in cross-section below

Fig. 6 viser borhullet ifølge fig. 5 etter-at innholdet i røret er satt under trykk. Fig. 6 shows the drill hole according to fig. 5 after the contents of the tube have been pressurized.
Enkelte av de sprengstoffer som be-nyttes idag. kan uten fare pakkes ferdig fra fabrikken i dertil egnete pakninger, mens man ved andre sprengstoffer, for eksempel ammoniumnitratblandinger, av sikkerhets-hensyn foretrekker å blande sprengstoff-komponentene sammen på bruksstedet, for direkte ifylling i et borhull. Det er imidler-tid for mange sprengningsoperasjoner av betydning at sprengstoffet kan bringes til å utfylle fullstendig det borhull som de skal plaseres i, enten de er pakket i pakninger eller de fylles direkte i borhullet. Some of the explosives used today. can be safely packaged from the factory in suitable packages, while with other explosives, for example ammonium nitrate mixtures, for safety reasons, it is preferred to mix the explosive components together at the point of use, for direct filling into a borehole. It is, however, important for many blasting operations that the explosives can be brought to completely fill the borehole in which they are to be placed, whether they are packed in gaskets or they are filled directly into the borehole.
Pakkingen av sprengstoff foretas ifølge oppfinnelsen ved hjelp av et lengdeveis oppslisset rør 10, hvis slisskantpartier 11 og 12 overlapper hverandre. Fortrinsvis er omkretslengden for det overlappende parti omtrent 1/10 av rørets totale omkrets-lengde. The packing of explosives is carried out according to the invention by means of a longitudinally slotted pipe 10, whose slotted edge portions 11 and 12 overlap each other. Preferably, the circumferential length of the overlapping portion is approximately 1/10 of the total circumferential length of the pipe.
Røret som anvendes er stivest mulig, i lengderetningen, men tillater at slisskantpartiene 11 og 12 føres fjærende mot og fra hverandre. Det er fordelaktig å frem-stille røret av plast, som for eksempel poly-vinylklorid. Herved kan røret, når det har en rørdiameter på fra 1 til 10 cm,, ha en godstykkelse på omtrent 0,1—1 mm. The tube that is used is the stiffest possible, in the longitudinal direction, but allows the slit edge parts 11 and 12 to be guided springily towards and away from each other. It is advantageous to make the tube from plastic, such as polyvinyl chloride. In this way, the pipe, when it has a pipe diameter of from 1 to 10 cm, can have a material thickness of approximately 0.1-1 mm.
I fig. 1 er det vist et plastrør 10 som er fremstillet ved ekstrudering. Det fremgår av figuren at det fremstilte rør i tverrsnitt har spiralform, hvor slisskantpartiene eller overlappingspartiene 11 og 12 har en viss fri avstand i radialretningen. In fig. 1 shows a plastic pipe 10 which is produced by extrusion. It is clear from the figure that the manufactured pipe has a spiral cross-section, where the slit edge parts or overlapping parts 11 and 12 have a certain free distance in the radial direction.
Plastrøret fremstilles fortrinsvis på følgende måte: Et sirkulært rør ekstru- The plastic pipe is preferably produced in the following way: A circular pipe is extruded

I fig. 2 er røret 10 vist i en fjærende innspent tilstand. Røret bringes til denne tilstand ved at partiene 11 og 12 «vrenges» In fig. 2, the tube 10 is shown in a resiliently clamped state. The pipe is brought to this state by parts 11 and 12 being "twisted"

I fig. 4 er det med en pil 15 vist be-vegelsesretningen for dysen 14 i forhold til røret 10 og med piler 16 er det vist ut-strømningsretningen for sprengstoffet fra dysen 14. In fig. 4, an arrow 15 shows the direction of movement of the nozzle 14 in relation to the pipe 10 and arrows 16 show the direction of flow of the explosive from the nozzle 14.

På tilsvarende måte kan også tennsatsen eller liknende innsettes i røret. in the gap 19 between the parts 11 and 12 so that it is hidden and protected inside the packing. In a similar way, the igniter or similar can also be inserted into the pipe.

I fig. 6 er røret vist i en tilstand hvor In fig. 6, the tube is shown in a state where
man har oppnådd at røret har øket sin diameter oppimot borhullsdiameteren uten at innholdet i vesentlig grad har har sivet ut av røret. Dette er oppnådd ved at rørets innhold er satt under trykk fra enden. Selv om sprengstoffet siver ut mellom partiene 11 og 12 før røret har inntatt den stilling it has been achieved that the pipe has increased its diameter in relation to the borehole diameter without the contents having leaked out of the pipe to a significant extent. This has been achieved by pressurizing the contents of the pipe from the end. Even if the explosive leaks out between parts 11 and 12 before the pipe has taken that position
som er vist i fig. 6 får man likevel fylt hele borhullets tverrsnitt med sprengstoff. ' which is shown in fig. 6, the entire cross-section of the borehole can still be filled with explosives. '
