摘要： A fluid cutting head (8) of the type having a plurality of nozzles in a rotatable nozzle assembly (9) for cutting a bore hole in rock, has nozzles being arranged to be supplied with high pressure drilling fluid, forming jets positioned to cut adjacent rock. The nozzles include one or more generally axially facing pilot nozzles (1 and 2) and one or more generally radially facing reaming nozzles (3, 4, 5 and 6), at least the pilot nozzles being characterised by a non-tapering outlet section such that the jet issuing therefrom is of substantially constant cross-section in a zone immediately adjacent the outlet section. The pilot nozzles are located in a leading part (26) of the rotatable nozzle assembly (9), having a minimised diameter, while the reaming nozzles are located in the following part (27) of the rotatable nozzle assembly (9), formed in a step-wise fashion to keep the reaming nozzles close to the rock face.

摘要： A fluid drilling head of the type adapted to cut a bore hole in rock by the rotation of a swivel assembly (5) within a body (1) typically has high pressure fluid nozzles providing cutting and reaming jets at the leading end (7) with the reaming jets angled to provide reaction forces to rotate the swivel assembly (5). The invention provides a positive displacement fluid driven motor (3) coupled to the swivel assembly (5) to control the rotational speed of the swivel assembly by restricting fluid flow to the motor through a metering nozzle (8).

摘要： A fluid drilling head (1) for drilling a bore hole through rock, the fluid drilling head having a rotatable nozzle assembly (2) incorporating a plurality of nozzles (3, 4, 7, 8 and 9) arranged to form fluid jets (5, 6, 10, 11, 12) when provided with a supply of drilling fluid under pressure. The fluid jets include pilot jets (5, 6) directed in the general direction of movement of the drilling head and reaming jets (10, 11, 12) directed generally radially and arranged to enlarge the initial hole formed by the pilot jets. A gauging ring (13) is provided, located behind the cutting head and sized to the intended diameter of the bore hole, the gauging ring being arranged to slide axially relative to the rotating cutting head between a rearward position where the reaming jets are exposed, and a forward position where some or all of the reaming jets are shrouded by the gauging ring, and inhibited from enlarging the diameter of the bore hole.

摘要： The position of an underground drilling head is represented on a visual display unit (1) by way of separate displays of two planes, typically a plan view (2) and a sectional side view (6). A trajectory line (5, 7) representing the path of the drilling head is displayed in each plane against relevant information such as mine roadways (3) or desired optimum position limits represented by envelope lines (8, 9). This enables an operator to make simple real time decisions in performing steering operations.
摘要翻译：地下钻头的位置通过两个平面的分开的显示器（通常为平面图（2））和截面侧视图（6）表示在视觉显示单元（1）上。相对于诸如矿山道路（3）或由包络线（8,9）表示的期望的最佳位置极限的相关信息，在每个平面中显示表示钻头的路径的轨迹线（5,7）。这使得操作者能够在执行转向操作时做出简单的实时决定。

摘要： A method of steering a fluid drilling head in an underground borehole drilling situation is provided by rotating the flexible hose through which high pressure is provided to the drilling head and providing a biasing force on the drilling head. The hose can be rotated from a remote surface mounted situation by rotating the entire surface rig (13) in a horizontal plane about a turntable (24) causing the vertically orientated portion of the hose (11) to rotate about its longitudinal axis. The biasing force can be provided in a number of different ways but typically results from the use of an asymmetrical gauging ring on the fluid drilling head.
