Abstract:
A method for controlling an automated drilling process on a work machine, the method comprising: obtaining, from at least one input, data determining operations of the work machine; generating reference data based on the data determining previous operations of the work machine in substantially the same area; detecting a region of interest in the reference data; and controlling, in response to the work machine or its drilling process approaching a point corresponding to the region of interest in the reference data, the work machine to provide an operator with an option to manually assist the operations of the work machine at said point.
Abstract:
Drill hole sequence planning equipment (14) includes a position determining module (18) for determining an initial location of a mobile drill rig (12). A selection module (24) selects a destination location for the drill rig (12). A corridor establishment module (26) establishes a corridor between the initial location of the drill rig (12) and its destination location, the corridor having a selected width. A processing unit (28) is responsive to the modules (18, 24 and 26) for selecting a hole location of each hole within the corridor to be drilled by the drill rig (12) sequentially as it moves from its initial location to its destination location.

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 horizontal direction drilling system comprises a power pack coupled to a source of compressed air and a water reservoir and forms a mixture of compressed air, water, and oil. The horizontal direction drilling system further comprises a steerable horizontal drill. The steerable horizontal drill includes an air powered reciprocating hammer, and a drill head. The steerable horizontal drill receives the mixture to power the reciprocating hammer. The drill head includes a drill face and the mixture exits the steerable horizontal drill through the drill face.
Abstract:
The present invention relates to an arrangement in a drill rig. The arrangement comprises an inlet valve placed before the inlet to a displacement compressor that is used for supplying a flow of air via a pressure vessel to at least one flushing hole in the surface of a drill bit. The arrangement is used for detecting a reduced flow of air through the at least one flushing hole in the surface of the drilling bit. The arrangement further comprises means for detecting the quantity of air flowing through the inlet valve placed before the inlet to the displacement compressor. The invention furthermore relates to a method for indirectly monitoring of a reduced air flow through at least one flushing hole in the arrangement above.
Abstract:
The present invention relates to a method and a device for calibration of joint means in a rock-drilling rig comprising at least one joint means, wherein a joint motion speed for the said joint means is controllable by means of control means, and wherein the influence of the said control means upon the motional speed of the said joint means is designed to be controlled by a control parameter. The method comprises the steps of setting a value for a control parameter, determining whether the deviation between the joint motion speed obtained by means of the control parameter value and a reference joint motion speed falls below a certain threshold value, increasing/reducing the value for the said control parameter if the said deviation exceeds the said threshold value, and automatically repeating the above steps until the said deviation falls below the said threshold value. The invention also relates to a device and rock-drilling rig.
Abstract:
The present invention is intended to reduce the effect of a backlash in a swivel joint (7) for rotation of a feeder (3) on a boom (2) in a drilling rig, when the feeder (3) is to be brought into a new spatial position, through a measure and means to rapidly rotate the drive member, at least in the swivel joint (7) which has the greatest susceptibility to said backlash, into a position in which further adjustment results in a physical movement of the feeder (3). This is achieved in that when a movement of the relevant swivel joint (7) is ordered by the control system, a control loop in the drilling rig control system is initiated, which for a short time adjusts and drives the drive member in the swivel joint (7) at a high rate of adjustment until a movement of the feeder (3) can be detected, following which the control system adjusts the entire movement of the boom (2) and the feeder (3) at the speed ordered by the control system.
