Blasting is the most commonly used excavation technique in mining and civil engineering applications. In this study, the authors applied a new system consisting of accelerometers, which are compact and standalone type to monitor the blasting-induced vibrations and investigate if it is possible to evaluate the characteristics of surrounding rock masses in a Taru-Toge tunnel in Central Japan. In addition, the damage around the blasted holes may be used to infer in-situ stresses. The authors also attempted to infer in-situ stresses using the damage of blasted-holes and compared with those from AE method and other techniques. The authors will describe the outcomes of these studies in the paper and discuss the implications in tunneling.
