Evaluation of Parameters Affected on the Blast Induced Ground Vibration (BIGV) by Using Relation Diagram Method (RDM)

Abstract

This paper presents the application of relation diagram method (RDM) to determine contribution of the parameters affected on the blast induced ground vibration. There are two types of parameters: controllable and uncontrollable parameters. The study focused on controllable parameters. The more effective parameters for ground vibration at the point of interest are ground vibration in the point of blast (PPV in-blast) and geological structures. The more effective parameters for the ground vibration at the point of blast are explosive amount per delay, burden and stemming. If desired fragmentation is obtained from the blast, then geological structures should be modified by creating artificial discontinuities. If one desires to reduce the level of vibration in the point of blast, then the following parameters should be modified; explosive amount per delay, burden, stemming, and hole diameter.
