Leaching Line Deployment on Mine Slopes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mining techniques fail to efficiently extract minerals from mine slopes due to hazardous and inefficient deployment of leaching lines, resulting in unrecovered minerals.
Innovation Solution
A system and method for vertically deploying leaching lines along the slope of a leach pad using an elevated guidewire and a leaching line deployment apparatus, enabling safe and efficient mineral extraction from previously inaccessible areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional techniques are used to deploy leaching lines along the slope, then worker safety is compromised and deployment is hazardous, but mineral recovery from slope areas is achieved
Solution Approach 1:
An automated deployment system acts as an intermediary between workers and the hazardous slope environment. The system uses a winch mechanism and specialized deployment apparatus to lower leaching lines vertically along the slope face, eliminating the need for workers to physically access dangerous slope areas while still achieving complete mineral recovery from previously inaccessible zones
2Ease of operation
If leaching lines are deployed horizontally along the slope perimeter, then deployment is safer and easier, but mineral extraction from slope areas becomes inefficient and areas are left unrecovered
Solution Approach 1:
The invention transitions from horizontal deployment along the slope perimeter to vertical deployment down the slope face. By changing the deployment dimension from horizontal to vertical, the system achieves both operational ease (deployment from accessible rim areas) and complete mineral extraction (lines extend vertically to treat entire slope surfaces including previously inaccessible areas)
3Productivity
If the leach pad grows taller with successive layers, then mining capacity increases, but the slope becomes longer and potentially steeper making deployment more hazardous
Solution Approach 1:
The automated deployment system serves as a mediator that decouples leaching line installation from worker exposure to slope hazards. As the leach pad grows taller with successive layers, the winch-based deployment apparatus handles the increased vertical distance, allowing workers to operate safely from the accessible rim while the system manages the hazardous vertical deployment to greater heights

AI summary
The present disclosure provides a system for vertical deployment of leaching lines onto a slope of a mine leach pad. The system includes an elevated guidewire having a first end disposed at a top of the slope and a second end disposed at a bottom of the slope; the elevated guidewire being elevated above a surface of the slope; a deployment apparatus moveably coupled to the elevated guidewire and having one or more attachment mechanisms disposed thereon; and one or more leaching lines coupled to the attachment mechanisms; wherein movement of the deployment mechanism from the top of the slope to the bottom of the slope pulls the one or more leaching lines down the slope and deploys the one or more leaching lines vertically onto the surface of the slope.
