Abstrakt: This paper is intended to reveal the blasting impact on the dam stability that located within certain distance from the source of the explosion. The blasting activity is required to support the production of igneous rock quarry to remove in-situ blocky hard-rock material. It may cause seismic wave propagation as illustrated as the energy propagates through the earth body then produces vibrations in the rock mass. Level of the vibration varies depending on a blasting design and geological setting. The application of blasting methods should take into consideration the rock condition so that the resulting of the blast vibration is in a safe condition for surrounding facilities and infrastructures. A fact in the field that the blasting activities is being conducted relatively adjacent to the dam; therefore the blast vibration presumed may cause damages due to seismic effects on the dam structure; so the safe distance should be determined strictly. The magnitude of seismic impacts due to blasting activities is measured by vibration-meter namely BlastMate-III® tool by means of measuring ground vibration that collected, processed, and analyzed by using software Blastware-10 to obtain some seismic parameters. By simulating the seismic load as input parameters into the geotechnical model, stability of the dam structure and level of damage (deformation) can be predicted. [ABSTRACT FROM AUTHOR]
