| Apparatus for drilling a bore hole comprises a hammer (3) and a series of dual wall drill tubes (2). The hammer (3) is supplied with compressed air and is for use in applying successive percussive blows to a percussive drill cutting bit for taking core samples from the bottom of the bore hole while drilling same. An upstanding rig (37) is provided at surface level to support the hammer (3) and drill tubes (2) and to transmit push-down or pull-up movement thereto. First means (32) indexes rotationally the bit for drilling purpose and is operable by a portion of the supply of air. Second means conducts from the bottom end of the bore hole that portion of air used by and exhausted from the percussive cutting bit (27) and having core particles entrained therein. Third means comprises an annular flushing jet (7) to direct a portion of air upwardly through a sampling tube (6) co-axial with the drill tube (2) and hammer (3) to induce a venturi to assist in conducting core particle entrained exhaust air upwardly. | ||||||

| The invention concerns a method and a device for directional drilling of a hole (3), in particular when drilling curved holes for mining, drift mining or similar, whereby a drill support (4) is used in the form of a flexible continuous drill tube with a proximal end and a distal end, that at the end of the drill support distal end is connected a down hole assembly (5) comprising a drill bit (13) for forming a drill string, which is fed into the gradually forming hole. To avoid and minimise the occurrence of “stick slip” during directional drilling, according to the method, the drill support (4) while drilling is taking place is held fixed at its proximal end against rotation outside the borehole and the rotating motion for indexing the drill bit (13) around an axis extending in the direction of drilling is performed in the area between the drill support’s distal end and the drill bit while drilling is in progress. | ||||||

| A rotating inner member (106) is used to drive a downhole tool (104) housed within the hollow outer member (108) of a dual-member drill string. The downhole tool preferably will be adapted t receive rotational energy from the inner member. In a preferred embodiment, the downhole tool is an electric generator connected to a downhole electric device (118). In another preferred embodiment the downhole tool is a mechanical transmission that uses the rotational energy from the inner member to drive a non-electric tool, such as a downhole hammer. This invention will increase the consistency and efficiency of downhole energy production. | ||||||

| Un appareil pour forer un trou de mine comporte un marteau (3) et une série de tubes de forage à paroi double (2). Le marteau (3) est alimenté en air comprimé et est utilisé pour appliquer des soufflages de percussion successifs à un trépan à percussion pour retirer des échantillons de carottes du fond du trou de mine pendant le forage de celui-ci. Un appareil vertical (37) est prévu au niveau de la surface pour soutenir le marteau (3) et le tube de forage (2) et pour leur transmettre le mouvement d'enfoncement ou de remontée. Un premier mécanisme (32) positionne de manière rotative le trépan à des fins de forage et peut être actionné par une partie de l'alimentation en air. Un deuxième mécanisme conduit du fond du trou de mine la partie d'air utilisée par le trépan à percussion (27) et refoulée par celui-ci entraînant avec elle des particules de carottes. Un troisième mécanisme comporte un jet de rinçage annulaire (7) pour diriger une partie de l'air vers le haut à travers un tube d'échantillonnage (6) coaxial par rapport au tube de forage (2) et au marteau (3), afin d'induire un tube de Venturi à aider à conduire vers le haut l'air d'évacuation entraînant des particules de carottes. | ||||||

Die Erfindung betrifft eine Schlag- und Bohrvorrichtung zum Reinigen von Rohren oder Kanälen, die aus einem ruhenden Teil und einem sich bewegenden Schlagkolben mit einem Werkzeugträger für ein Schlagbzw. Bohrwerkzeug besteht. Die Schlagbewegung wird hydraulisch mit Hilfe einer unter Hochdruck stehenden Flüssigkeit unter Beteiligung eines Vorsteuerschiebers (50) und eines Hauptsteuerventiles (7) bewirkt. Der als Differentialkolben ausgebildete Schlagkolben (10) wird auf seiner kleineren Kolbenfläche ständig beaufschlagt und auf seiner größeren Kolbenfläche abwechselnd druckbeaufschlagt und entlüftet, ebenso im Vorlauf der Vorsteuerschieber (50). Eine Relativbewegung zwischen dem Vorsteuerschieber (50) und dem Hauptsteuerventil (7) bewirkt die Druckbeaufschlagung bzw. Entlüftung der, größeren Kolbenfläche des Schlagkolbens. In Weiterbildung wird die hydraulische Umsteuerung des Vorsteuerschiebers (50) hilfsweise von einer mechanisch bewirkten übernommen, damit die Vorrichtung trotz einer hydraulischen Störung am Vorsteuerschieber (50) noch weiter arbeitet. |

| 29 | DOWNHOLE TOOL | PCT/GB0202381 | 2002-05-20 | WO02095180A2 | 2002-11-28 | SUSMAN HECTOR FILLIPUS ALEXAND |
| There is disclosed a downhole tool for generating a longitudinal mechanical load. In one embodiment, a downhole hammer (10) is disclosed which is activated by applying a load on the hammer and supplying pressurised fluid to the hammer. The hammer includes a shuttle valve (14) and a piston (16) that are moveable between first and further positions, seal faces (18, 20) of the shuttle valve (14) and piston (16) being released when the valve and the piston are in their respective further positions, to allow fluid flow through the tool. When the seal is released, the piston (16) impacts a remainder of the tool to generate a mechanical load. The mechanical load is cyclical by repeated movements of the shuttle valve (14) and piston (16). | ||||||

| An exemplary embodiment of the jet hammer includes an outer sleeve, impact assembly, and a valve assembly. The impact assembly is positioned in sliding relation to the outer sleeve to provide the impact of the jet hammer. The valve assembly generally comprises a cap screw, adjustment sleeve, valve port, inner compression spring, outer compression spring, and lock nut. The inner compression spring is relatively less compressible than the outer compression spring. In operation, fluid enters the valve assembly and acts on the compression springs forming an operational seal between the valve assembly and the impact assembly thereby slidingly displacing the outer sleeve from the impact assembly. Once the pressure acting on the valve assembly is released, the main compression spring decompresses forcefully causing an impact which is translated onto the obstruction or item to be struck. | ||||||
