Abstract

Ground vibrations due to blasting processes are one of the fundamental problems in the mining and civil excavation industry which may cause severe damage to the structures. It is mostly recommended that a detail comprehensive vibration control is required. This paper presents the results of ground induced vibration at a metro rail station excavation site in the heart-of-city of Bangalore. This study was carried out to control ground induced vibration, fly rock near to sensitive structures, mostly to the city civil court and the buildings of Sir M Visveswaraya college and like statue, school, public and private structures closed to 10-15m. More than 60 blasts were done under control supervision of government officials. The maximum charge/delay, charge per hole, delay in between holes and rows were established on basis geological rock mass. Ninety percent rock was excavated to construct underground metro stations. The fly rock was control by optimum stemming lengths and by using suitable fly control rubber mat.
