The generated seismic waves can damage the surrounding structure and livelihood thus it is essential to monitor and predict the blast-induced ground vibration in mines. They differ from the ground vibrations caused by earthquakes in terms of seismic source, the amount of available energy and traveled distances. Ground vibrations are acoustic waves that propagate through the rock. Extreme levels of structural vibration triggered by ground vibration from blasting can result in damage to or failure of structures. However, a fragmentation accounts for only 20-30 % of the total amount of explosive energy used and remaining large quantity of explosives energy during charging can result in undesirable scenarios like fly rocks, back breaks, over breaks, extreme noise and vibration impacts on communities. It is a more economical process for mining rock excavation. Blasting is an essential component for fragmentation of the overburden and mineral deposits.

Obtained results were compared based on correlation of determination (R 2) and standard error between recorded and predicted values of PPV. A three-layer, feed-forward back propagation neural network consists of 6 input parameters, 5 hidden neurons, and one output parameters were trained. The results are very promising and the recorded PPV varies from 0.191 mm/s to 8.60 mm/s.

The data has been transmitted by ZigBee (IEEE 802.15.4) protocol.

Eleven blasts PPV were recorded at different locations using wireless sensor network prototype system. In this paper, an attempt has been made to monitor the BIGV with low-cost wireless sensor network (WSN) and prediction of peak particle velocity (PPV) using an artificial neural network (ANN) technique at ACC Dungri limestone mine, Bargarh, Odisha, India. Usage of a high amount of explosive causes ground vibrations that are harmful to the nearby habitats and dwellings. Blast-induced ground vibration (BIGV) is an undesirable environmental issue in and around mines.
