Ground vibrations, air blasts, fly rocks, back breaks, noises are the ill effects of blasting which are unavoidable but certainly can be minimized up to permissible level to avoid damages to the surrounding environment, structures. Among all the ill effects, ground vibration is a major concern to the engineers, designers, and environmentalists. Various laws have been communicated by scientists and are being adopted to keep in check the ground vibration levels. This study is conducted to predict the blast induced ground vibration (peak particle velocity) using ANN, USBM and CMRI formulae for the safety of the structures existing near surface coal mines. The data obtained from the different mines are analyzed and the correlation for different models are established to see their predictability.
