ABSTRACT
The Existence 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.
