Abstract:
When excavating a rock cavern one round at a time by a rock drilling rig (1) comprising at least one drilling boom (3) and at least one drilling unit (4) arranged in the drilling boom (3), holes (21) of a round are drilled in accordance with a drilling pattern (14) designed for the round. In order to drill each single hole (21), the drilling unit (4) is con¬ trolled into a rotating angle (Φ) which carries out a location (21') and direction determined for the particular hole (21) in the drilling pattern (14) designed for the particular round. The rotating angle (Φ) of the drilling unit (4) to be used for drilling the hole (21) is determined on the basis of the rotating angle (Φ) of the drilling unit (4) carried out in connection with the drilling of one or more previously drilled holes (21).
Abstract:
The invention relates to a rock drilling rig and a method for downhill driving of a rock drilling rig. The rock drilling rig (1 ) comprises electric drive equipment (16), the drive motor (M) of which serves as a primary brake in long-term downhill driving. The drive motor thus converts kinetic energy into electric energy, with which an energy storage (B) is charged. To consume surplus electric energy, a hydraulic system (13) or a compressed air system (50) is turned on. A hydraulic pump (34) and a compressor (54) are driven by an electric motor (33, 55).
Abstract:
A laser alignment device for a drill rig having an elongate drill rod, the laser alignment device including a head unit having at least a pair of laser emitting devices mounted independently to one another thereon, each of the laser devices movable in one plane only and oriented in substantially opposite directions to one another, an attachment means to attach the head unit to a drill rig and a length adjustable assembly to adjust the separation distance between the head unit and the drill rod, wherein the alignment device is used to align at least the azimuth of the drill rod relative to survey marks.
Abstract:
An autonomous drilling rig (200), including a carriage including a mast (204), a rotary head (202) configured to traverse up and down the mast (204), and a wireless transmission system. The wireless transmission system includes a wireless transmitter (208) mounted on the rotary head (202) and configured to send a wireless signal to a wireless receiver (210). The wireless transmitter (210) includes a first connector (209) configured to engage with a first sensor, wherein the sensor measures at least one operating parameter. The wireless transmission system further includes the wireless receiver (210) configured to receive the wireless signal from the wireless transmitter (208), wherein the wireless signal comprises the at least one measured operating parameter, and a display unit (610) operatively connected to the wireless receiver (210) and configured to display the measured operating parameter.
Abstract:
A method and a device for controlling a drill rig (1) which includes a carrier vehicle with at least one feed-beam (3), wherein a drill machine (2) is movable to-and-fro, wherein rig parameters are set by a control unit (6) and wherein each one of a plurality of operating modes (M1-M6) includes specified operating settings for different operating parameters of the rig. Each operating mode (M1-M6) is selectable such that operation of the rig is related to a particular type of rock, in which drilling is to be performed, and each operating mode (M1-M6) includes operating settings that are adapted to the prevailing type of rock. The invention also concerns a drill rig.
Abstract:
The invention relates to a method and equipment for displaying holes to be drilled when drilling holes into rock with a rock-drilling rig (1) having control equipment and a display belonging thereto and measuring means for defining the direction and position of a drill rod, by using a pre-designed drilling plan defined in a three-dimensional coordinate system, in which a starting point (19a to 21 a) and end point (19b to 21 b) is defined for each hole to be drilled. In the invention, a base plane (18) running through the end point (19b to 21 b) of the hole and parallel to the projection plane is defined for each hole (19 to 21), and a projection of the intersection of a hole or its extension created when drilling in accordance with the current location of the drill rod and the defined base plane is displayed with a graphical location symbol on the projection plane.
Abstract:
The present invention relates to a method for determining the position of at least one rock reinforcing bolt in a tunnel or a mine, with the bolt installation being arranged to be carried out by means of a drilling rig, with the said drilling rig comprising at least one boom with a first end and a second end, with the said first end being attached to a carrier via at least one articulated connection, and with the said boom being arranged to carry an installation tool. The method comprises the steps of determining a position of the said carrier using means arranged on the drilling rig, determining at least one angle of rotation for the said boom in relation to the carrier by determination of an angle of rotation for the said articulated connection, and determining the position of the rock reinforcing bolt in the tunnel or mine on the basis of the said position of the carrier and the said determined angle of rotation. The invention also relates to an arrangement.
Abstract:
The invention relates to a method for drilling rock, wherein holes (2 to 7; 9a to 11a) to be drilled are determined prior to drilling as a drilling pattern wherein for each hole (2 to 7; 9a to 11a), a starting place, direction and hole depth for drilling are determined with respect to the rock to be drilled. In the invention, hole-type-specific drilling parameters are determined for the holes (2 to 7; 9a to 11a) to be drilled, and during a drilling phase a drill rig automatically selects drilling parameters for each hole (2 to 7; 9a to 11a) to be drilled on the basis of the hole type of the particular hole.
