Definitions

  • the invention concerns a boring rig for extraction boring below ground, including a boring unit, and, supported by the boring unit, a boring aggregate having a cutting head.
  • the cutting head is pivotally adjustable for boring in different directions.
  • the invention also concerns a method of maneuvering a boring rig.
  • Bore rigs for extraction boring are previously known, wherein a carrier vehicle supports a boring unit with a cutter head.
  • the boring unit is swingable in a plane at a right angle to a general direction of movement of the boring rig with respect to the substructure of the boring rig.
  • the cutter head is driven axially from a position inside the thrusting device by means of rotation and forcing in order to provide the boring operation.
  • a boring rig according to the background art is intended for and functions well for underground operation but are time consuming to set up and its usefulness for production boring is limited to specific applications.
  • a boring unit of this kind is pivotal for action only over an angle of about 10° below a horizontal plane to about 30° over a horizontal plane.
  • the invention relates to a boring rig being more flexible and allowing boring with further enhanced precision at the same time as reduced set-up time.
  • the boring unit which has a length direction and two lateral directions, at one end, as seen in said length direction, is connected over a first swing joint to a first drive unit, that the boring unit at its second end, as seen in said length direction, is connected over a second swing joint to a second drive unit, that each drive unit has at least two wheels which are arranged individually drivable, said at least two individually drivable wheels being positioned in sideways relationship to each other, and that a first angular position of the first swing joint as well as a second angular position of the second swing joint are adjustable, whereby the position of the boring unit in lateral direction as well as an angular direction of the length direction of the boring unit are adjustable.
  • the invention also concerns a method of manoeuvring a boring rig.
  • a first angular position of the first swing joint as well as a second angular position of the second swing joint are adjustable, whereby the position of the boring unit in lateral direction as well as an angular direction of the longitudinal direction of the boring unit are adjustable.
  • Said at least two individually drivable wheels can be arranged on a common wheel axis or be provided with separate wheel axes.
  • Boring rig here means a machine equipped with a boring unit, which supports a boring aggregate, to drive units and further optionally one or more support units connected to the boring unit.
  • Longitudinal direction here means the direction from the first to the second swing joint irrespectively if the boring unit is constructed such that any other one of its dimensions, for example laterally, exceeds the dimension in this longitudinal direction.
  • “Lateral directions” here means directions perpendicular to said longitudinal direction as seen in a base plane for the boring unit, said base plane being defined as an imagined plane through the boring unit being parallel to a horizontal plane when the boring unit is ideally positioned horizontally.
  • the invention makes alternative movement patterns for the boring unit possible:
  • the result will be fine-adjustment of an exactly desired position in lateral direction, angular direction and also in longitudinal direction.
  • the invention finds its application, besides in rock boring machines of so called slot-boring type, also in respect of rock boring machines for raise boring and for box hole boring.
  • Adjustment of the swing joints is suitably performed in a particular setting mode.
  • the adjustment can be performed entirely manually through individual/sequential or at least partly simultaneous manoeuvring of the swing joints/the drivable wheels, whereby a resulting positioning direction of the boring unit can be verified, with ocular inspection or with the aid of instruments in respect of a should-position and a should-direction.
  • control system for manoeuvring the boring rig in set-up mode, wherein for example an operator over entry devices such as for example a joy-stick or any other per se known entry device feeding data into the control system which in turn actuates the swing joints and/or the drivable wheels for obtaining positioning and direction as desired.
  • first and the second swing joints in a particular driving mode are manoeuvrable together for facilitating driving of the boring rig for example in case of tight passage of curves between extractions sites.
  • Having the swing joints manoeuvrable together here means that the same swing angle is automatically set for both swing joints for swinging the boring rig.
  • one of the first or the second drive units is provided with a lockable rocking joint for allowing rocking in respect of the boring unit.
  • the lockable rocking joint suitably adjoins to the swing joint between the drive unit in question and the boring unit which gives the possibility of a simplified pendulum construction.
  • the first drive unit includes a power unit for supplying the boring rig with hydraulic liquid under pressure and that the second drive unit is arranged for receiving drill string components and for providing drill string components to the boring unit.
  • the power unit can be a combustion motor or an electric motor.
  • the second drive unit is an operator's unit and exhibits an interface for operator co-operation.
  • This can for example be realised through an operator's cabin been equipped with the usual driving controls and switches for set-up mode and driving mode.
  • the boring rig is equipped with distance control means including driving controls and switches allowing manoeuvring of the boring rig from a distance.
  • the first and the second drive units are constructed as modules being connectable as desired to the boring unit forming a boring module in order to form said first or second swing joint together therewith.
  • the boring rig can be easily rearranged such that it can be adapted for boring in a desired lateral direction.
  • the first and second swing joints being constructed as quick release joints with mechanical as well as hydraulic quick couplings. This can be realised when it comes to the swing joints in that a swing shaft is simply retractable from a seat being formed by swing joint components on each module.
  • Said first and second swing joints are suitably manoeuvrable through any one of:
  • the boring unit is provided with lifting jacks for lifting the entire boring rig. This gives firstly an opportunely to align the boring rig at an accurate level in the drift, secondly to align the parts of the boring rig to each other after having determined the position of the boring unit. Normally the second drive unit has to be aligned in respect of and lined up with the boring unit for allowing drill string components to be transferred between these bore rig parts.
  • the boring unit is provided with stabilizing jacks (for fastening the entire boring rig against adjacent rock sides.
  • the invention also concerns a method for maneuvering a boring rig for boring below ground, wherein the boring rig includes: a boring unit with a longitudinal direction and two lateral directions, and a boring aggregate being supported by the boring unit and being equipped with rotation and thrusting means for a cutting head for boring in directions at an angle to said longitudinal direction.
  • the boring unit at one end, as seen in a length direction, over a first swing joint is swung in respect of a first drive unit, and at its second end, as seen in said length direction, over a second swing joint in respect of a second drive unit.
  • Each drive unit is driven by two wheels which are arranged individually drivable on a wheel axis, and the first and the second swing joint are maneuvered individually in an adjusting mode to adjust the position of the boring unit in lateral direction as well as an angular direction of the length direction of the boring unit.
  • a boring rig in Fig. 1 globally includes three modules, that is a boring module in the form a boring unit 1 with a boring aggregate having means for rotation and thrusting of a cutting head 6, a power module in the form of a first drive unit 2 and an operator module in the form of a second drive unit 3.
  • Different machine part such as driving means, stabilisation means, a drill string component supply and drill string joining means are included in the boring rig. Some of these machines are not shown in the Figures.
  • the operation of the boring rig is controlled by a computerised control system 28.
  • 10 is a rock having a relatively thin ore-bearing formation 11 extending therethrough.
  • the extension and approximate thickness of the ore-bearing formation has been determined by drilling from the surface of the ground above the formation.
  • a drift 12 has been made through the rock so as to have the ore-bearing formation 11 extending therealong.
  • the extension and approximate thickness t of the ore-bearing formation determined is indicated in Figs. 1 and 2 by two spaced interrupted lines extending along the drift.
  • a base plane of the boring unit 1 is indicated with B.
  • the cutting head 6 having a diameter d substantially corresponding to the approximate thickness t of the ore-bearing layer 11 determined is used to drill a first hole H 1 along an axis A 1 extending along an approximate mid-plane M of the layer 11 ( Fig. 1 ).
  • a second hole H 2 is drilled along a second axis A 2 also extending along the approximate mid-plane of the ore-bearing layer 11.
  • the axes A 1 and A 2 are parallel if the layer is a 'plane' layer, but they may as well be non-parallel if the layer is curved.
  • the spacing s between the axes A 1 and A 2 is chosen such that the holes H 1 and H 2 intersect or overlap one another as shown in Fig. 1 . In other words, the spacing s is less than the drill diameter d.
  • more or less material is left unbroken in areas where two holes do not intersect.
  • the drill cuttings yielded are continuously collected.
  • An example how this can be realised is to arrange a suction equipment adjacent to the cutter head, said suction equipment discharging loosened material to a collecting station for subsequent further handling.
  • the bore string consists of a number of axially aligned, connected bore string components 30, which are added to the bore string in a manner which is not part of the invention and therefore not further discussed here.
  • FIG. 3 is shown an alternative boring rig in greater detail.
  • the boring unit 1 which includes the base plane B, (see Figs. 1 and 2 ), has a body 4 which supports a boring aggregate 5 with rotation and trusting means for a cutter head 6.
  • the boring aggregate 5 is in the shown example swingably adjustable for boring in directions essentially perpendicular to a longitudinal direction L of the boring unit 1.
  • the invention also relates to boring rigs having boring units equipped with boring aggregates being swingably adjustable for boring in other directions than essentially perpendicular to the longitudinal direction L.

As is indicated above it is also possible to arrange supported wheels otherwise than on a common wheel axis and also to arrange separate individually controllable electric motors at each one of the wheels.
  • This unit has an interface for the co-operation with an operator in an operator's cabin 31 and a supply of drill string components 31 which through a suitable supply mechanism are made accessible for the boring unit 1 during boring operation of the boring rig.
  • the first and the second swing joints 14 and 15 are only moveable in the base plane B and prevent movements at angles thereto.
  • a lockable rocking joint 19 (indicated with interrupted lines), in the first drive unit 2, allowing a rocking movement of the first drive unit 2 in respect of the boring unit 1 and the second drive unit 3 for facilitating driving on uneven ground.
  • the second drive unit 3 includes two individually drivable wheels on a wheel axis, whereof one is indicated with 10 on Fig. 3 .
  • the boring unit 1 exhibits lifting jacks 13 arranged on its body 4, in principle one lifting jack 13 in each one of the four corners of the body 4, for the application against ground and for support and/or lifting of the entire boring rig from its support.
  • the drive units 2 and 3 are free to be aligning in line with the boring unit 1.
  • stabilizing jacks 16 which when actuated will come into stabilizing application against a rock side in the drift where the boring rig is arranged to operate.

  • the boring rig according to the invention is suitably made modular in such a way that the first and the second drive unit 2 and 3 respectively can be connected to an optional side (seen in the length direction L) of the boring unit 1.
  • the modules are releasable from each other and fastenable to each other in both the intended positions.
  • the first as well as the second swing joint being constructed to be simply releasable swing joints.
  • the swing joints there can be included extractable swing shafts allowing separation of the modules when they are extracted. Hydraulic conduits are advantageously arranged with quick couplings for quick switching during rearranging the boring rig.
  • the first and the second drive units are suitably individually drivable such that they for example with the addition of one or two support wheels can be individually brought to be driven their selves and be controlled for displacement to a chosen position for (re-) arranging or for any other purpose.
  • the boring unit 1 has no drive wheels and is normally displaced only with the first and the second drive units connected. It is, however, not excluded that the boring unit 1 is provided with or connectable with wheels to facilitate displacement, swinging etc. through for example towing thereof in order to, for example, change boring directions 180°.
  • Fig. 6 shows diagrammatically a method sequence according to the invention, wherein:
  • the events above can in certain cases occur simultaneously or partly simultaneously.
  • the above is followed by fastening into the drift, setting the boring aggregate, performing boring etc.
  • Figs. 7a - 7c show diagrammatically different positions during a set-up sequence for the boring rig according to the invention.
