Abstract
The Gxistencc of quarries near residential areas is now
becoming inevitable. In order to protect building
Structures against quarry operations hazards, there is need
to quantify response of these structures to hazards. One of
such hazards is the dynonic loads emitted and transmitted
through the soil and air media due to blasting of the rock
for its excavation. In this research, effort has been made
to model the dynamic loads transmitted from the blasting point
to the structure. Two path-ways are identified - air and
soil - for the transmission of the loads onto a building
structure. An assessment of the effect of weather conditions
at the time of blasting on the relative contribution of the
loads travelling through the air and soil media onto a
building structure in the vicinity was made. Modal analysis
was utilised effectively for obtaining response of a building
structure modelled into an elastic, three degree of
