Networking Scheme and Consumption Analysis Method of Digital Electronic Detonator for Rock Excavation in Hydropower Project
Since the mandatory application of digital electronic detonators in the blasting excavation of hydropower projects in 2021,the research on the blasting networking design scheme,actual consumption and cost analysis of digital electronic detonators is still in the blank stage.The authors start with the comparative analysis of the design scheme of digital electronic detonator and non-electric millisecond detonator blasting network,study the difference of blasting network mode between the two detonators,and theoretically derive the consumption adjustment coefficient of the two detonators.At the same time,the unconstrained support vector machine model is used to construct the functional relationship between detonator consumption and rock grade and excavation section.The consumption adjustment coefficient of digital electronic detonator after replacing non-electric millisecond detonator is calculated,and the accuracy of the calculated data is verified by single variable test.The results show that the measured data results are consistent with the theoretical derivation results and the mathematical model analysis results,which proves the reliability of the two research methods.
