Advanced TDLS System for CO2 & Blackdamp Detection in Mines

点击翻译按钮获取中文摘要

Carbon Dioxide (CO2) builds up daily in coal mines from oxidation of coal, humanrespiration, rock blasting, fires, rotting timbers, etc. Without adequate air ventilation in allareas of the mine to dilute excess CO2, a ”blackdamp” atmosphere can build up where theoxygen level is depleted and CO2 levels can increase up to 20%, creating an immediatehuman asphyxiant risk due to displacement of oxygen. Under this project OptoSci proposes toexamine the feasibility of using various novel laser, optical fibre and gas sensor designs inaddition to signal processing schemes to allow intrinsically, safe, low maintenance monitoringof CO2 over hundreds of points to the sensitivity levels required by mine regulations.
