SYNOPSIS

To develop infrastructure projects like tunnels, canals, open excavation for hydro power stations, underground metros, etc., a large quantity of soil and rock mass are to be removed. Rock fragmentation by blasting is the cheapest and easy methods of excavating the hard rock mass. Expertise is required in planning and execution of blasting in such projects as the locations may be very near to human habitats and other important structures, which needs to be protected from blasting. So, the blasting engineer needs to select suitable explosives, initiating devices, and carefully decide the blast geometry parameters keeping in view the rock properties. Blast analysis is required in critical cases where ground vibrations and air over pressure is to be monitored using sophisticated geophones and burden rock movement and fly rock ejection can be monitored using high speed video cameras. This talk highlights the details of few construction projects in India like a pipeline project, hydro power project and an underground metro where controlled blasting was carried out.
