Abstract

Several holes are drilled to the chosen depth and a pressurised jet is lowered into the hole. The jet which is usually water opens up fissures in the rock, forming a channel through to an adjacent hole. The feed tube is movable in the directions indicated by the arrows. The tube is supported by a stand on which there is a tippable platform and the angle set to adjust the jet angle.

Description

459 929 I fig. 2 visas en sprickdrivningsanordning bestående av en central del 26 och tvâ manschetter 27. Manschetterna 27 trycksätts med vätska från en pump 20 via en ledning 25. 459 929 Fig. 2 shows a crack drive device consisting of a central part 26 and two cuffs 27. The cuffs 27 are pressurized with liquid from a pump 20 via a line 25.

Sprickdrivningsanordningens centraldel 26 matas med vatten från en tank 23 av en pump 22 via en behållare 21 som innehåller distanselement 19 och en ledning 24. Härigenom trycksätts sprickanvisningen 6 och omrâdet mellan manschetterna 27. På detta sätt drivs en spricka, exempelvis 18, till ett intilliggande borrhâl 4. Samtidigt infürs distanselement 19 i sprickan för att förhindra att berget helt återgår till ursprungsläget när trycket försvinner.The central part 26 of the crack drive device is fed with water from a tank 23 by a pump 22 via a container 21 containing spacer elements 19 and a line 24. This pressurizes the crack instruction 6 and the area between the cuffs 27. In this way a crack, for example 18, is driven to an adjacent borehole 4. At the same time, spacer element 19 is inserted into the crack to prevent the rock from completely returning to its original position when the pressure disappears.

Distanselementen kan exempelvis bestå av små kulor.The spacer elements can, for example, consist of small balls.
