Subway Atmosphere Monitoring System in Coal Mines

Mining in Colombia represents a high percentage of the national GDP (Gross Domestic Product), however despite the regulations required by the Ministry of Health and Social Protection, concerning occupational safety for mining employees, safety processes are insufficient due to the presence of methane gas and lack of oxygen in coal mining work, which consequently causes accidents such as asphyxia, hypoxia, anoxia, loss of consciousness, death, explosions, fires, among others. The objective of this book is to share with the scientific community the development of a system capable of supporting the process of measuring methane gas and oxygen concentrations and thus preserve the life of one of the most risky work in Colombia.
