Dynamic Working Area Definition for Rock Drilling Rigs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current rock drilling rig systems rely on fixed, predefined working area approximations that do not accurately reflect the true drilling capabilities, leading to unreliable operator decisions during optimization processes.
Innovation Solution
A method and system that dynamically determine and update the working area of a rock drilling rig based on current input parameters such as orientation and hole parameters, using a control unit and display to provide a graphical representation of reachable holes, incorporating kinematic models and sensor data for precise reach determination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a fixed working area is displayed around the rock drilling rig, then the display is simple and easy to implement, but the working area definition is inaccurate and does not reflect true drilling capabilities
Solution Approach 1:
The working area definition transitions from a static fixed shape to a dynamic representation that automatically adjusts based on current rig orientation and hole parameters. The control unit continuously updates the working area boundaries by calculating reach distances using stored kinematic models whenever orientation or hole parameters change, ensuring the displayed working area always reflects true drilling capabilities without manual intervention.
2Reliability
If pre-determined hole parameters are used, then the system is simple to operate, but the working area representation is only an approximation and cannot be trusted for optimization decisions
Solution Approach 1:
The control unit continuously monitors current orientation parameters from sensors and current hole parameters from input devices, comparing these real-time values against stored kinematic models to recalculate the working area. This feedback loop ensures the displayed working area always corresponds to the actual drilling capabilities given current conditions, providing reliable information for operator decision-making without requiring manual updates.
Solution Approach 2:
The system automatically determines and updates the working area definition by itself using stored kinematic models and current sensor data, without requiring operator intervention to recalculate reach distances. The control unit performs self-updates whenever orientation or hole parameters change, making the system both reliable and easy to operate.
3Measurement precision
If the working area is updated dynamically based on current parameters, then the accuracy of drilling capability assessment is improved, but the computational requirements and system complexity increase
Solution Approach 1:
Kinematic models defining the relationship between rig orientation, hole parameters, and boom reach distances are pre-calculated and stored in the control unit's memory during system setup. This preliminary preparation allows the control unit to perform rapid lookups and simple calculations during operation, achieving accurate dynamic working area updates without requiring complex real-time computations or advanced processors.

AI summary
A method for defining a working area of a rock drilling rig including the steps of determining at least one current input parameter, determining a working area that defines a reach of the drilling unit in a control unit on the basis of the at least one current input parameter and at least one fixed reach parameter, displaying a graphical representation of the working area on a display, and re-determining the working area and updating the graphical representation of the working area dynamically in response to a change in the input parameters. The current input parameter may be, for example, an orientation of the rock drilling rig or a hole parameter.
