地下爆破作业产生的CO有害气体的色敏监测与催化抑制
Research on Carbon Monoxide Coordinated Control Technology for Underground Blasting Operations-Integrated Application of Catalytic Suppression and Colorimetric-Sensitive Monitoring
摘要
Abstract
Underground blasting,as a core process in mining and tunnel construction,generates hazardous gases such as carbon monoxide(CO),which pose a serious threat to operational safety.Due to the strong enclosure of underground space and limited ventilation conditions,traditional ventilation methods and water-sealing methods are inadequate for controlling CO concentrations.Moreover,the delayed response and the need for sample pretreatment of conventional gas sensors cannot meet the millisecond-scale dynamic release characteristics of blasting field.To address the technical challenges of controlling and monitoring the dynamic release of CO during underground blasting,this study proposes an integrated ″catalytic suppression-colorimetric monitoring″ system.A hierarchically porous Co3O4 catalyst was prepared via hydrothermal synthesis,and its formulation was optimized based on oxygen balance theory,achieving a 58.23%reduction in CO generation from explosives.The results indicate that adding Co3O4 at 5%of the explosive mass significantly lowers the CO concentration at the working face,while Pd/TiO2 with 0.6%Pd loading exhibits the best performance for CO monitoring.This study provides an innovative solution for establishing a trinity safety system of ″generation suppression-dynamic monitoring-intelligent regulation″in underground engineering.关键词
