Real-Time Drill Hole Bottom Positioning Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rock drilling methods require pre-designed drilling patterns, which can be cumbersome and inefficient, especially when successive rounds differ, as they necessitate manual design and dedicated designers, and do not account for actual drill hole positions during the drilling process.
Innovation Solution
An apparatus and method that determine the forthcoming position of a drill hole bottom based on the current location and direction of the drilling tool and planned length, allowing for real-time adjustment and indication of drill hole positions relative to realized holes, eliminating the need for pre-defined patterns and enabling precise drilling without manual designers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If pre-designed drilling patterns are used, then drilling holes can be systematically arranged, but manual design work and dedicated designers are required, increasing device complexity and time consumption
Solution Approach 1:
The drilling system performs self-positioning by automatically determining the forthcoming drill hole bottom position based on current tool location and direction, eliminating the need for external manual pattern design. The system serves itself by using its own operational parameters to calculate and indicate the next drill hole position.
Solution Approach 2:
The system calculates and indicates the forthcoming drill hole bottom position before actual drilling occurs. This preliminary determination allows the operator to plan ahead and position the tool accurately at the starting point of the next drill hole, improving workflow efficiency.
2Manufacturing precision
If pre-designed drilling patterns are used, then a complete drilling plan can be established, but it cannot account for actual drill hole positions during the drilling process, reducing adaptability
Solution Approach 1:
The system uses feedback from the actual drilling process by detecting the current tool position and direction, then calculating the forthcoming drill hole bottom position based on this real-time information. This closed-loop approach allows the system to adapt to actual drilling conditions rather than following a rigid pre-designed pattern.
Solution Approach 2:
The drilling position determination is dynamic rather than static. The system continuously updates the forthcoming drill hole bottom position based on the current tool location and direction, allowing the drilling pattern to adapt dynamically to actual drilling conditions and variations.
3Productivity
If pre-designed drilling patterns are used, then drilling can proceed systematically, but the operator must follow the pattern strictly, reducing ease of operation
Solution Approach 1:
The system automatically determines and indicates the next drill hole position, serving itself rather than requiring the operator to manually follow a pre-designed pattern. This maintains systematic drilling for productivity while giving the operator flexibility to adapt to actual conditions.
Solution Approach 2:
The system performs preliminary calculation of the forthcoming drill hole bottom position, providing the operator with advance information about the next drilling location. This allows the operator to plan ahead and execute drilling operations more efficiently without being constrained by a rigid pre-designed pattern.

AI summary
An apparatus and method for assigning drill holes. The apparatus is arranged to determine a forthcoming position of a bottom of a new drill hole before it is drilled. The forthcoming position of the drill hole bottom is determined on the basis of the current location and direction of a tool and a planned length of the drill hole.
