Solution Overview

Problem

Current drilling pattern design programs are cumbersome, slow, and difficult to modify, making it inefficient to design and edit drilling patterns for rock cavern excavation.

Innovation Solution

Introducing a method and software product that designates a master hole for each group of holes, allowing editable properties such as location, depth, direction angle, and charge, enabling automatic determination of other drill hole properties and easy modification of the drilling pattern.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional drilling pattern design programs are used, then drilling patterns can be designed, but the design process is cumbersome and slow

Engineering Contradiction:
Improvedrilling pattern design speedVSAvoiddrilling pattern design ease
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The drilling pattern is segmented into master holes and dependent holes. Master holes are independently designable units that define key parameters, while dependent holes automatically inherit properties from master holes. This segmentation allows designers to work with fewer independent elements, significantly reducing design time and complexity while maintaining full control over the drilling pattern.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system performs preliminary actions by automatically generating dependent holes and their properties based on master hole definitions before the actual design process is complete. When a master hole is defined, the system proactively creates all associated dependent holes with inherited properties, eliminating the need for manual configuration and accelerating the design process.

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If traditional drilling pattern design programs are used, then drilling patterns can be designed, but it is difficult to change finished drilling patterns later

Engineering Contradiction:
Improvedrilling pattern editabilityVSAvoiddrilling pattern modification complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The drilling pattern is segmented into master holes and dependent holes. Master holes are independently designable units that define key parameters, while dependent holes automatically inherit properties from master holes. This segmentation allows designers to work with fewer independent elements, significantly reducing design time and complexity while maintaining full control over the drilling pattern.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system implements dynamic property inheritance where dependent holes automatically update their properties when master holes are modified. This dynamic relationship allows the drilling pattern to adapt automatically to design changes, making it highly versatile and easy to modify without requiring complex manual adjustments to each individual hole.

Inventive Principle:
Principle #15Dynamics

3Manufacturing precision

If detailed properties are defined for each drill hole individually, then precise control is achieved, but the design process becomes time-consuming

Engineering Contradiction:
Improvedrill hole property precisionVSAvoiddrilling pattern design time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The drilling pattern is segmented into master holes and dependent holes. Master holes are independently designable units that define key parameters, while dependent holes automatically inherit properties from master holes. This segmentation allows designers to work with fewer independent elements, significantly reducing design time and complexity while maintaining full control over the drilling pattern.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system uses copying by allowing dependent holes to inherit properties from master holes. Instead of defining properties for each hole individually, the system creates copies of master hole properties and applies them to multiple dependent holes automatically. This ensures consistent, precise property definition across the entire drilling pattern while dramatically reducing the time required for design.

Inventive Principle:
Principle #26Copying

AI summary

The invention relates to a method and a software product for designing a drilling pattern, and further to a rock drilling rig, in the control unit of which a software product may be executed for designing the drilling pattern. For a group of holes (14, 15, 16, 32, 17) of the drilling pattern (12), at least one master hole (13a, 13e, 17a, 17b, 35, 45, 48) can be determined which comprises at least one dominating factor. The properties of at least one other drill hole are determined on the basis of the dominating properties of the master hole. A master hole may be a hole location master, hole depth master
