Injuries and fatalities in Colombian mining emergencies (2005-2018): a retrospective ecological study.

Area of Science:

• Occupational Health and Safety
• Mining Engineering
• Public Health

Background:

• Mining is a significant economic sector in Colombia.
• There is a lack of comprehensive data on mining-related injuries and fatalities in Colombia.
• Global trends show a decrease in mining injuries in developed nations, contrasting with the Colombian situation.

Purpose of the Study:

• To describe the occurrence and characteristics of mining emergencies in Colombia from 2005 to 2018.
• To analyze the types of events, mine types, extracted minerals, and outcomes (injuries and fatalities).
• To assess data quality using Benford's Law.

Main Methods:

• Retrospective ecological study design.
• Analysis of mining emergencies data from the National Mining Agency (2005-2018).
• Inclusion of variables such as location, event type, legal status, mine type, mineral extracted, and number of injured/fatalities.
• Application of Benford's Law to evaluate data reliability.

Main Results:

• 1,235 mining emergencies were recorded, resulting in 751 injuries and 1,364 fatalities.
• Major causes included collapses, polluted air, and explosions, predominantly in coal and gold mines.
• Illegal mines accounted for a significant proportion of emergencies and showed a higher relative risk of injuries and fatalities.
• Benford's Law analysis suggested underreporting of mining disasters.

Conclusions:

• The incidence of mining emergencies, injuries, and fatalities is rising in Colombia.
• Illegal mining operations present a disproportionately higher risk to worker safety.
• This study provides the first comprehensive overview of mining emergencies in Colombia, underscoring the need for improved data collection and safety interventions.
