  • Correction model for CO detection in the coal combustion

    In the process of coal combustion, some typical and easytodetect index gases are produced, such as CO, CO 2, and SO 2 (Shi et al, 2021) Accurate detection of a change in the concentration of these gases can provide a reliable criterion for the identification and early detection of hidden dangers posed by coal combustion and can reduce falseAs a common hazard, coal spontaneous combustion (CSC) causes the loss of coal in piles and mines To rapidly and reliably forecast CSC, a portable and powerful detection system based on a laser spectroscopic technique is proposed, to precisely measure gaseous inhibitors; the technique uses a single, distributedfeedback diode laser emitting at 233 μm as a sensing light source for dual speciesEarly detection system for coal spontaneous combustionHazardAVERT®is an electromagnetic proximity detection system designed to increase personnel safety and awareness while working in and around mobile machinery It was developed to prevent crushing and pinning type accidents in underground mining environmentsProximity Detection for Coal Mines Strata Worldwide
