Prediction of Vibrations Due to Blast at the Hiré Mine, Côte D’Ivoire

Côte d'Ivoire has, in order to diversify its economic resources, decided exploit mineral reserves. Industrial gold mining began 1991 with the opening of Ity mine department Zouan-Hounien, west country. Several regions country have seen mines open. In Loh-Djiboua region, Divo, Hiré opened 2013.

From results research work, company requests and obtains 2017, State d'Ivoire, extension operations, direction city Hiré, possibility making blast two fifty dwellings, posing problem proximity The situation appears unprecedented sector d'Ivoire. Blast is source nuisance, including vibrations. Our study focused on prediction vibrations related shots. method consisted determining, formula Oriard, constants site predict them, generated by explosive blast.
