Abstract

A canal was proposed to be excavated by blasting nearby a village with hutments and an overhead water tank in very close proximity. The structures mentioned were as near as 18 m from the proposed excavation. Trial blasts were conducted by CSIR-CIMFR to ascertain the vibration attenuation parameters and based on the studies a controlled blast design was recommended. This included use of estimated charge per delay and recommended blast design while using non-electrical initiation system and taking advantage of decoupled charges. The blasting over a length of around 100 m was thus excavated without any damage to the nearby structures. A total flyrock control was observed and attained in the entire excavation by using blast mats. The study describes the methods adopted and results obtained during the excavation
