Environmental monitoring in mining sites is crucial for ensuring worker safety and reducing ecological impacts. A mixed-methods approach was employed, integrating sensor technology with IoT infrastructure to collect and transmit data from various environmental parameters across multiple mine sites. Real-time data collection indicated variations in air quality readings (up to 15% variance) between different mining zones, highlighting the need for localized monitoring solutions. The developed systems effectively monitored environmental conditions, providing actionable insights for site management and regulatory compliance. Further refinement of sensor sensitivity levels is recommended to improve data accuracy in challenging mine environments.
