Solution Overview

Problem

Mining machinery, such as blasthole drills, produce excessive dust that reduces operator visibility and poses hazards, with existing dust suppression systems often being manually controlled and inefficient, leading to excessive energy and water consumption.

Innovation Solution

A system and method that uses a controller to automatically detect dust levels and machine operating statuses, adjusting water flow and suction levels in dust suppression systems based on real-time data from particulate and hole depth sensors to optimize dust control, reducing energy and water usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If manual control of dust suppression systems is used, then operator visibility can be maintained, but the system cannot adapt to changing dust conditions and consumes excessive resources

Engineering Contradiction:
Improvedust suppression adaptabilityVSAvoidenergy consumption
Core Design Contradiction:
Adaptability or versatilityVSLoss of energy

Solution Approach 1:

The system employs sensors to continuously monitor dust levels and provides feedback to the controller, which automatically adjusts water flow and suction power accordingly. This closed-loop control enables the system to adapt to changing dust conditions while consuming only the necessary amount of energy and water resources.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The dust suppression system operates autonomously by detecting dust levels and self-adjusting its suppression measures without manual intervention. The controller automatically modulates water injection flow rates and vacuum suction power based on real-time sensor data, enabling the system to serve itself and adapt to varying operational conditions.

Inventive Principle:
Principle #25Self-service

2Object-affected harmful factors

If maximum water flow and suction levels are used, then dust control is effective, but water and energy consumption increases significantly

Engineering Contradiction:
Improvedust control effectivenessVSAvoidwater consumption
Core Design Contradiction:
Object-affected harmful factorsVSQuantity of substance

Solution Approach 1:

The system dynamically adjusts water flow rates and suction power levels based on real-time dust measurements rather than operating at fixed maximum levels. The controller continuously modulates these parameters to maintain effective dust control while minimizing resource consumption, adapting the suppression intensity to match actual dust generation conditions.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes operational parameters (water flow rate, suction power) dynamically based on detected dust levels. Rather than maintaining constant maximum parameters, the controller adjusts these parameters up or down according to the severity of dust conditions, achieving effective dust control with optimized resource usage.

Inventive Principle:
Principle #35Parameter changes

3Object-affected harmful factors

If maximum water flow and suction levels are used, then dust control is effective, but operation is delayed due to frequent water refills

Engineering Contradiction:
Improvedust control effectivenessVSAvoidoperational productivity
Core Design Contradiction:
Object-affected harmful factorsVSProductivity

Solution Approach 1:

The system dynamically adjusts water flow rates based on actual dust generation, preventing excessive water consumption that would require frequent refills. By matching water usage to actual dust control needs, the system maintains effective dust suppression while extending operational periods between water refills, thereby improving productivity.

Inventive Principle:
Principle #15Dynamics

4Extent of automation

If manual dust suppression control is used, then system complexity is low, but automation and remote operation capability is reduced

Engineering Contradiction:
Improvedust suppression automationVSAvoidsystem complexity
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The automated dust suppression system uses sensors to monitor dust levels and provides feedback to the controller, which automatically adjusts suppression measures. This feedback mechanism enables remote and autonomous operation while managing system complexity through standardized control architecture and integration of off-the-shelf components.

Inventive Principle:
Principle #23Feedback
