Solution Overview
Problem
Existing mesh installation methods on rock surfaces, such as in underground mining, lack precision and efficiency in determining and maintaining the planned positions of meshes, leading to potential gaps or overlaps that may not adequately protect against falling rocks.
Innovation Solution
A system comprising a processor and memory configured to obtain a digital meshing plan, map planned mesh positions to a coordinate frame stationary with respect to the rock surface, and control the installation of meshes using a mesh installation rig, ensuring accurate placement and overlap based on a coordinate frame stationary with respect to the rock surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual positioning methods are used to install meshes on rock surfaces, then operational flexibility is maintained, but positioning precision and installation efficiency deteriorate
Solution Approach 1:
The patent replaces manual mechanical positioning with an automated control system that uses coordinate frame transformation and digital meshing plans. The control apparatus automatically calculates mesh positions based on the rig's location and orientation, eliminating the need for manual measurement and positioning while improving precision and efficiency.
Solution Approach 2:
The patent introduces a coordinate frame transformation system as an intermediary between the physical rock surface and the digital planning system. This intermediary layer translates the rig's current position and orientation into accurate mesh positioning coordinates, enabling precise automatic installation without direct manual intervention.
2Productivity
If human operators determine mesh positions on-site, then adaptability to local conditions is maintained, but installation efficiency and consistency deteriorate
Solution Approach 1:
The patent implements preliminary action by pre-calculating and storing digital meshing plans that specify optimal mesh positions and orientations. These plans are generated before installation based on the rock surface geometry and protection requirements, allowing the system to automatically execute efficient, consistent positioning without on-site decision-making delays.
Solution Approach 2:
The control apparatus continuously monitors the rig's position and orientation during installation and uses this feedback to update the coordinate frame transformation. This ensures that mesh positions are automatically adjusted to maintain precision and consistency, improving productivity while keeping the operation simple through automated adaptive control.
3Manufacturing precision
If meshes are installed without coordinated positioning systems, then installation speed is maintained, but positioning accuracy and protection effectiveness deteriorate
Solution Approach 1:
The patent replaces time-consuming manual measurement and calculation with automated coordinate frame transformation. The system automatically computes accurate mesh positions based on the rig's known location and orientation, significantly reducing installation time while improving placement accuracy through digital planning and automated control.
