Abstract
An apparatus and method for planning a drilling sequence. The solution relates also to a rock drilling rig and to a computer program product. The apparatus searches several possible drilling scenarios for drilling a given drilling pattern. Different actions required by the scenarios have given costs and the executed algorithm calculates total costs of found scenarios. Scenarios with the lowest costs are selected.
Claims14
An apparatus for planning a drilling sequence for a rock drilling rig comprising:
- at least two drilling booms, which are provided with drilling units for drilling drill holes to a face of a rock surface;
- at least one control unit including a processor arranged to execute a drilling sequence planning program, the control unit being provided with a drilling pattern including drill hole data on drill holes to be drilled, wherein the drill hole data has at least position data of starting points of the drill holes to be drilled, the control unit also being provided with data on drilling booms, wherein the data on drilling booms includes data on a number of the booms, reach of the booms, and further, positions of the booms relative to the drilling pattern, wherein execution of the drilling sequence planning program in the processor of the apparatus is configured to generate a drilling sequence for the provided drilling pattern, wherein the drilling sequence includes data on a drilling order of the drill holes and selection of a boom for drilling each drill hole, the control unit being configured to search several drilling steps further for each drilling unit, and based on that, being configured to produce several possible drilling sequence scenarios each of which defines a different drilling order, drilling unit selection and transfers of the drilling units between neighboring drill holes, wherein the control unit is provided with at least one data element including pre-determined rules for defining cost values for several possible actions of the drilling steps, the control unit being configured to detect actions required by the drilling steps of the searched drilling sequence scenarios and is configured to calculate total costs for the searched drilling sequence scenarios based on the pre-determined rules, and wherein the control unit is configured to select one drilling sequence scenario of the examined scenarios having the lowest total cost for the several following drilling steps.
A method of planning a drilling sequence for a rock drilling rig including a plurality of drilling booms intended for drilling, the method comprising:
- executing the planning in at least one control unit;
- providing the control unit with a drilling pattern including drill hole data on drill holes to be drilled;
- providing the control unit with data on the drilling booms;
- executing a drilling sequence planning program in a processor of the control unit and generating a drilling sequence for the provided drilling pattern, wherein the drilling sequence includes data on a drilling order of the drill holes and selection of a boom of the plurality of booms for drilling each drill hole;
- searching several drilling steps further for each drilling boom for producing several possible drilling sequence scenarios each of which defining a different drilling order, drilling unit selection and transfers of the drilling booms between neighboring drill holes;
- providing the control unit with at least one data element having pre-determined rules for defining cost values for several possible actions of the drilling steps;
- detecting actions required by the drilling steps of the searched drilling sequence scenarios and calculating total costs for the searched drilling sequence scenarios based on the rules;
- and
- selecting one drilling sequence scenario of the examined scenarios having the lowest total cost for the several following drilling steps.
