This research has been carried out in the limestone quarries of Assiut Cement Company (CEMEX). Ground vibrations and airbl st overpressure induced by bench blasting in the quarries of the co mpany have been measured and evaluated to find out the site-specifi c attenuation and to assess the risk of structural damage. Statistical t reatment has been applied to the measured data.Engineering at Assiut University have a long and distinguished history. The oldest university building was established in 1957 in el-wleedyaa. Today, we continue to educate individuals, offer a wide variety of undergraduate and postgraduate programs in all departments, and give our students the freedom to choose the stream appropriate to their skills and interests.
