Determination of critical thresholds for CO exceedance in return air corner induced by coal spontaneous combustion and establishment of a graded early warning index system

CO released from the oxidation of residual coal in goaf areas causes CO exceedance in the return air corner of coal mines, and clarifying the critical thresholds for CO exceedance in the return air corner and establishing a graded early warning index system are of great significance for the early wa...
