Underground mining remains hazardous despite major investment in occupational safety and health systems. Behaviour-centred investigations can stop at the immediate unsafe act and therefore miss organisational, engineering, workplace and regulatory conditions that shape frontline performance.
This study developed and preliminarily validated the Zambian Mining Accident Prevention Model (ZAMPAM), a context-sensitive systems framework for underground mine accident investigation and prevention.
A pragmatic retrospective case-study design centred on Mopani Copper Mines (Nkana Mine) analysed 214 accident investigation reports from 2005–2014, supported by organisational safety records, regulatory documents and published mining-safety evidence. Accident narratives were coded across five system dimensions. Twenty per cent of records (n = 43) were independently double-coded, yielding overall Cohen’s κ = 0.82. The source study reports chi-square tests, binary logistic regression, correlation analysis and principal component analysis. Framework development integrated Reason’s organisational accident model, Rasmussen’s risk-management framework, STAMP, HFACS, Bowtie analysis and CCM.
The case-study evidence indicates that only 13.6% of analysed accidents were attributed to worker error as the sole cause. ZAMPAM-layer contributions were reported for organisational systems (89.7%), technical controls (82.2%), workplace conditions (78.5%), regulatory factors (76.6%) and human factors (68.2%), with an average of 3.9 layers implicated per accident. Falls of ground (31.8%) and mobile-equipment interactions (22.4%) were prominent mechanisms. Production pressure (OR = 3.42, 95% CI 2.15–5.44), weak supervision (OR = 2.89, 95% CI 1.78–4.69) and inadequate critical-control verification (OR = 2.41, 95% CI 1.52–3.82) were reported as predictors of accident severity. The framework retrospectively mapped 87% of cases and achieved Delphi contentvalidity ratios above 0.78 for all layers.
The findings support a shift from blame-oriented accident investigation toward systemsbased prevention. ZAMPAM links causal analysis to critical-control verification, leadership accountability and organisational learning. Because validation was retrospective and based principally ZAMPAM on a single mine, prospective multi-mine validation is required before claims of predictive effectiveness can be made.

Excerpt from the Book
1. Introduction
Mining is economically central to Zambia and remains a high-hazard industry. Zambia’s current national policy direction seeks to increase annual copper production to three million tonnes by 2031, increasing the importance of safety governance as underground operations expand and modernise. The safety challenge is not simply the presence of hazards, but the interaction of geological conditions, equipment, production systems, contractors, supervision, organisational decision-making and regulatory oversight.
Traditional accident investigations have often concentrated on immediate unsafe acts. This can produce corrective actions such as retraining, disciplinary measures or procedure revision while leaving production pressure, weak supervision, maintenance backlogs, engineering-control degradation, contractor integration and regulatory weaknesses insufficiently examined. Systems safety scholarship instead treats accidents as emergent outcomes of interacting socio-technical conditions (Reason, 1990, 1997; Rasmussen, 1997; Leveson, 2004, 2011). Recent mining research reinforces this position: Newnam and Dee (2026) identified 89 contributory factors and 173 relationships in systems analysis of mining fatalities, while Wang et al. (2026) found organisational factors exerted stronger influence on unsafe-behaviour intentions than individual factors.
The Zambian context adds features that deserve explicit representation: contractor-intensive work, ageing infrastructure, variable regulatory capacity, resource constraints, production pressures and uneven organisational maturity. Recent Zambian evidence also reports gaps between hazard knowledge and consistent adherence to procedures, while contemporary African work has called for stronger integration of CCM into governance (Phiri et al., 2025; Tembo & Nsefu, 2026).
This study therefore develops ZAMPAM as a five-layer framework linking regulatory environment, organisational management systems, technical and engineering controls, workplace conditions and human performance. It further embeds CCM and organisational learning so that investigation findings translate into prevention rather than ending at causal classification.

What are the central thematic areas covered in the work?
Core themes include systems safety theory, multi-layer accident causation, critical control management, contractor management, safety maturity models, and implementation frameworks for mining operations.
What is the primary research goal or question addressed?
The study aims to determine which recurrent system-level factors are present in historical underground mine accidents, how these factors interact, what drives accident severity, and how investigations can link to critical-control verification.
Which scientific methods and data sources were utilized?
The study employed a pragmatic retrospective case-study design analyzing 214 historical accident investigation reports from Mopani Copper Mines (2005–2014), supported by statistical analyses such as binary logistic regression, chi-square tests, and qualitative coding.
What topics are examined in the main body of the work?
The main body examines historical accident mechanisms, system-level contributing factors across five distinct layers, empirical severity predictors, engineering control failures, and a structured implementation roadmap.
Which key terms characterize the publication?
Key terms include underground mining, accident causation, systems thinking, critical control management, safety culture, occupational safety and health, Zambia, and ZAMPAM.
How does ZAMPAM differ from traditional accident investigation methods?
Traditional investigations frequently terminate at immediate unsafe acts and frontline worker error. ZAMPAM extends investigations outward and upward through five system layers to evaluate regulatory, organisational, technical, and workplace conditions.
What role does Critical Control Management (CCM) play in the model?
CCM serves as the bridge between causal explanation and active prevention by ensuring that every identified system weakness is translated into an owned, verified, and functional control measure.
What does the empirical data reveal about worker error as a sole cause?
The case-study evidence indicates that worker error was attributed as the sole cause in only 13.6% of analyzed accidents, demonstrating that multi-layer organisational and technical factors are predominantly involved.
What practical tools does the framework provide for mine operators?
The framework provides a structured 36-month implementation roadmap, an operational five-level safety maturity model, investigation prompts, and workflows to enhance executive accountability and barrier verification.
