Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current rock drilling methods rely heavily on driller skill and lack efficient parameter adjustment, leading to suboptimal drilling efficiency and speed, especially in varying drilling situations and hole types, where parameter changes are cumbersome or impossible during drilling.
Innovation Solution
The method groups holes by type and automatically selects drilling parameters based on the hole type, allowing for tailored parameter settings that enhance accuracy and efficiency by enabling quicker boom movement and optimized drilling phases.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If drilling parameters are manually adjusted based on driller experience, then drilling flexibility is maintained, but drilling efficiency and speed are reduced
Solution Approach 1:
The system pre-determines optimal drilling parameters for different hole types before drilling begins. The control unit stores multiple parameter sets corresponding to different hole types (e.g., exploration holes, blasting holes, support holes) and automatically selects the appropriate parameters based on the identified hole type, eliminating the need for manual adjustment during drilling.
Solution Approach 2:
The drill rig automatically selects and applies drilling parameters without requiring driller intervention. The control unit monitors drilling conditions, identifies the hole type, and autonomously adjusts parameters to optimize drilling performance, making the system self-regulating and independent of operator skill level.
2Speed
If drilling parameters are fixed in advance for different hole types, then drilling speed increases, but adaptability to exceptional situations is reduced
Solution Approach 1:
The system dynamically adapts drilling parameters based on real-time monitoring of drilling conditions and identification of hole types. The control unit can switch between different pre-stored parameter sets or adjust parameters within ranges based on actual drilling progress, rock conditions, and hole type requirements, maintaining both speed and adaptability.
Solution Approach 2:
The system stores multiple parameter sets for different hole types and enables dynamic parameter changes during drilling. The control unit can modify parameters such as drill bit rotation speed, feed rate, and hydraulic pressure based on the identified hole type and real-time drilling conditions, allowing optimization for both standard and exceptional situations.
3Manufacturing precision
If manual parameter setting is used for each hole, then drilling accuracy is maintained, but time consumption increases
Solution Approach 1:
The system pre-configures optimal parameter sets for different hole types before drilling begins. The control unit automatically identifies the hole type based on the drilling pattern and selects the corresponding pre-determined parameters, ensuring accurate drilling without requiring time-consuming manual adjustment for each hole.
Solution Approach 2:
The control unit monitors drilling parameters and conditions in real-time, providing feedback to automatically adjust parameters or trigger alerts when deviations occur. This feedback mechanism ensures drilling accuracy is maintained while eliminating manual parameter setting time, as the system self-corrects based on monitored conditions.

AI summary
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.
