Abstract: This paper presents part of the work on ground vibrations induced by blasting, and to estimate safe maximum charge per delay to protect the nearby structures. Blasting near sensitive areas has always been a cause of concern and utmost care has to be taken to keep the charge per delay below the stipulated level A number of field visits were made to collect the geotechnical data, and monitoring ground vibrations induced by blasting. A number of blasts were monitored to study various blast parameters related to blasting Overburden and Coal benches and to understand the effect of blast on the surrounding structures, and rock mass conditions at the mine site. Drilling is accomplished by tire mounted drill machine capable of drilling large diameter holes of 159mm. The drilling pattern of the mine benches is based on the rock formation of the particular bench and varies with the variation in strata from 4 m to 6 m. Holes were charged with Bulk Emulsion Explosives in association with Booster(...
