Abstract

Human response is complimentary to blasting near habitats. This often results in loss of productivity due to frequent halting of blasting due to complaints or inefficient blasting due to restrictions from regulatory authorities on charge per delay and size of the blasting. This paper discusses the methodology adopted to address the human response for mitigation of complaints to ensure productivity in a limestone mine in India. The method comprised of conducting trials in a phased manner, with calculated charge per delay and establishing an attenuation relationship of the vibration along with the frequency domain of the vibrations. On the basis of the vibration analysis the maximum charge per delay was fixed and proper approval from regulatory authorities was obtained for regular blasting. The data was further validated and cross checked at different times. A list of the habitats around the mine was prepared and systematic blast plan was evolved. This was followed by addressing of the problems on individual and mass level, educating the habitants about the vibrations and their impact on the houses, continuous monitoring and displaying of vibration data generated in each blast and addressing genuine problems while meeting the fake claims with firmness and shifting of habitants in nearby locations. With the application of systematic efforts the mine could achieve targets of production within a short span of time.
