African Mining Equipment Failure Dataset

Dataset Description

Overview

This dataset provides synthetic records of equipment failures, maintenance events, and condition monitoring data from mining operations across Africa. It is designed to support research in predictive maintenance, reliability engineering, and operations optimization for heavy mining equipment operating under African conditions.

The dataset models realistic failure patterns, maintenance regimes, and sensor-based condition indicators for fleet management systems typical of African mining operations.

Methodology

Reliability Engineering Framework

The dataset models equipment reliability using industry-standard parameters:

Mean Time Between Failures (MTBF) by equipment type:

Equipment	MTBF (hours)	MTTR (hours)
Haul Truck	2,500	8
Excavator	3,000	12
Drill Rig	1,800	6
Conveyor	5,000	4
Crusher	4,000	24
Loader	2,800	10
Grader	3,500	8
Pump	6,000	4

Failure Mode Distribution

Failure modes are distributed based on equipment-specific reliability data:

Haul trucks: Engine (25%), Transmission (20%), Hydraulics (20%), Electrical (15%), Tires (12%), Brakes (8%)
Excavators: Hydraulics (35%), Engine (25%), Undercarriage (20%), Electrical (12%), Bucket (8%)
Drill rigs: Drill string (30%), Hydraulics (25%), Compressor (20%), Rotation (15%), Electrical (10%)

Condition Monitoring Correlation

Sensor flags are correlated with failure modes to simulate predictive maintenance scenarios:

Oil analysis flags: 60% sensitivity for engine/transmission/hydraulic failures
Vibration flags: 70% sensitivity for bearing/motor/gearbox failures
Temperature flags: 55% sensitivity for engine/motor/hydraulic failures

African Operating Context

The dataset accounts for African mining conditions including:

Extended operating hours (high utilization)
Challenging maintenance logistics
Mixed fleet ages
Variable infrastructure quality

Limitations

Simplified Degradation: Actual equipment degradation follows complex physics not fully captured
Fleet Interactions: Dependencies between equipment failures not modeled
Supply Chain: Parts availability and logistics delays simplified
Environmental Factors: Dust, temperature, and humidity effects generalized
Operator Effects: Human factors in equipment operation not explicitly modeled

Ethical Considerations

Commercial Sensitivity: Real equipment reliability data is commercially sensitive; synthetic data enables research
Vendor Neutrality: Manufacturer distributions are illustrative, not endorsements
Safety Implications: Equipment failures can cause injuries; safety context important
Economic Impact: Downtime costs affect livelihoods; realistic but synthetic values used

Intended Uses

Appropriate Uses

Development of predictive maintenance algorithms
Benchmarking machine learning approaches for failure prediction
Fleet management optimization research
Reliability engineering education
Operations research methodology development

Inappropriate Uses

Actual maintenance scheduling without validation
Equipment procurement decisions
OEM performance comparisons
Warranty or insurance claims analysis
