Based on the cloud model theory and the principle of establishing evaluation index system,explosive consumption,limit vibrating velocity,efficient casting rate and volumetric expansion coefficient were applied to establish evaluation index system and then a comprehensive evaluation model was constructed for determining the casting blast effect in open-pit coal mine,which involved both fuzziness and randomness of the uncertainty.By choosing the measured casting blast parameters in Heidaigou open-pit coal mine and using the cloud model to evaluate them,the project was determined to be Grade II.This comprehensive evaluation cloud model was beneficial to optimize blasting parameters,improve operation efficiency and reduce production cost.
