Drilling Rig Navigation Correction via Orientation Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drilling rigs face challenges in maintaining accurate navigation during tunnel excavation due to uneven tunnel floors, ground instability, and unexpected debris, which can cause unwanted movement and deviation from the target coordinates.
Innovation Solution
An apparatus is provided that includes a processor and memory configured to control navigation of the drilling rig by determining its position and orientation, receiving data from a measurement device, detecting orientation changes, and initiating navigation correction actions to maintain accurate positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual navigation monitoring is used, then operator control is maintained, but navigation accuracy deteriorates due to delayed detection of orientation changes
Solution Approach 1:
The system continuously monitors the drilling rig's orientation using measurement devices (inclinometers, gyroscopes) and provides real-time feedback to the control system. When deviation from target coordinates is detected, the system automatically initiates correction actions, eliminating the delay inherent in manual monitoring and significantly improving navigation accuracy.
Solution Approach 2:
The navigation system performs self-correction by automatically detecting orientation changes and executing correction maneuvers without requiring continuous operator intervention. The drilling rig's control system autonomously adjusts the rig's position based on measurement data, reducing both time loss and improving precision.
2Measurement precision
If automatic navigation correction is implemented, then navigation precision is improved, but system complexity increases
Solution Approach 1:
The control system integrates multiple functions into a single automated navigation system that combines orientation measurement, deviation detection, correction calculation, and execution control. This multi-functional approach improves positioning accuracy while managing system complexity through consolidation rather than adding separate independent systems.
Solution Approach 2:
The system replaces manual mechanical navigation operations with an automated electronic control system that uses sensors and algorithms to detect and correct positioning deviations. This substitution improves precision while the modular electronic architecture manages complexity better than manual mechanical systems.
3Reliability
If continuous monitoring of orientation is performed, then navigation reliability is improved, but energy consumption increases
Solution Approach 1:
The system performs orientation monitoring at optimized intervals rather than continuously, balancing reliability requirements with energy conservation. Measurement devices are activated periodically to detect orientation changes, and the control system processes data at appropriate frequencies to maintain navigation reliability while minimizing energy consumption of the measurement and control systems.

AI summary
According to an aspect, an apparatus for controlling a drilling rig during drilling of a round in an underground mine is provided. The drilling rig may comprise a carrier, a drilling boom attached to the carrier and a measurement device associated with the carrier. The apparatus may be configured to control navigation of the drilling rig, the navigation comprising determining a position and orientation of the drilling rig with respect to a coordinate system of a drilling site. The apparatus may be configured to receive, during drilling of the round, data from the measurement device associated with the carrier. The apparatus may be configured to detect an orientation change of the carrier based on the data from the measurement device, and to initiate, during drilling of the round, a navigation correction action of the drilling rig based on detecting the orientation change. The apparatus may be configured in the drilling rig, or in a separate device, such as a server, a server node, or an individual processing unit with access to a computer-readable memory.
