Abstract
A method and a computer program for controlling a drilling cycle in a rock drilling apparatus, and a rock drilling apparatus. In accordance with the invention, each drilling unit in the rock drilling apparatus is monitored during a drilling period, and a drilling sequence of a control unit in the rock drilling apparatus is updated at predetermined intervals during the drilling period. The total time of the drilling and the time elapsed for different operations can be registered. In addition, according to an embodiment, the drilling sequence is changed during updating, if changes occur in the drilling conditions during the drilling period.
Claims18
A method for controlling a drilling sequence of a rock drilling apparatus,
- the rock drilling apparatus comprising:
- a base, at least one drilling unit arranged onto the base, the drilling unit comprising a drilling boom, a feeding beam connected to said drilling boom and a rock drill, which can be moved in relation to the feeding beam, and the rock drilling apparatus further comprising a control unit,
- the method-comprises:
- forming a drilling plan on the basis of the number, location and dimension of planned drilling holes before drilling, and storing the drilling plan together with drilling parameters associated with drilling control into the memory of the control unit;
- forming a drilling sequence in the control unit on the basis of the drilling plan and the drilling parameters, where the drilling order of the holes is determined and the drilling unit is selected for each hole;
- drilling in accordance with the drilling sequence the drilling holes determined in the drilling plan in the rock,
- monitoring the operation of each drilling unit during a drilling period, and
- updating the drilling sequence in the control unit on the basis of the monitoring during the drilling period.
A rock drilling apparatus comprising:
- a base,
- at least one drilling unit arranged onto the base,
- the drilling unit comprising a drilling boom, a feeding beam connected to the drilling boom and a rock drill, which is movable in relation to the feeding beam,
- a control unit arranged to form a drilling sequence on the basis of a drilling plan and drilling parameters for drilling holes according to the drilling plan in the rock, and wherein
- the control unit is arranged to monitor the operation of each drilling unit during a drilling period and to update the drilling sequence in the control unit on the basis of the monitoring.
A computer programme comprising program code, which performed in a processor of a control unit in a rock drilling apparatus causes the control unit to form a drilling sequence on the basis of a drilling plan and drilling parameters fed into the control unit, in which drilling sequence the drilling order of holes to be drilled and a drilling unit to be used for drilling are determined, and wherein
- the computer program causes the control unit to monitor the operation of the rock drilling units in the rock drilling apparatus during drilling, and
- the computer program causes the control unit to update the drilling sequence on the basis of the monitoring during drilling.
A computer programme comprising program code, which performed in a processor of a control unit in a rock drilling apparatus causes the control unit to form a drilling sequence on the basis of a drilling plan and drilling parameters fed into the control unit, in which drilling sequence the drilling order of holes to be drilled and a drilling unit to be used for drilling are determined,
- wherein the computer program causes the control unit to monitor the operation of the rock drilling units in the rock drilling apparatus during drilling,
- wherein the computer program causes the control unit to update the drilling sequence on the basis of the monitoring during drilling;
- and
- wherein the computer program causes the control unit to calculate on the basis of the monitoring the division of still un-drilled holes according to the drilling plan among the available drilling units in such a manner that the total duration of the remaining operations in each available drilling unit is approximately equal.
A computer programme comprising program code, which performed in a processor of a control unit in a rock drilling apparatus causes the control unit to form a drilling sequence on the basis of a drilling plan and drilling parameters fed into the control unit, in which drilling sequence the drilling order of holes to be drilled and a drilling unit to be used for drilling are determined,
- wherein the computer program causes the control unit to monitor the operation of the rock drilling units in the rock drilling apparatus during drilling,
- wherein the computer program causes the control unit to update the drilling sequence on the basis of the monitoring during drilling;
- and
- wherein the computer program causes the control unit to automatically control a drilling cycle of the rock drilling apparatus using the drilling sequence.
