The underground mine is about 25 feet beneath the ground level and 65 feet distant from the point where Seismometer is installed as shown in Figure 5.1, the explosive material is kept in the holes drilled to the ceiling of the mine and details of the explosion for which the data is been collected is given in Table 5.2. The application described in Section 5.1.1 was installed and launched in 4 smart phones (see Table 5.1 for details) and were placed at various distances from the Explosion point at the blasting site and the seismometer is installed on the ground level as shown in the Figure 5.1. The nearest distance of the smartphone from Explosion is 10 Feet and farthest being 70 Feet, the Seismograph is installed statically mounted on to the rock and it runs continuously looking for the explosive event, when there is a blast occurred then the Seismometer triggers and sends out the detected event report to the server. We have collected the raw data of the triggered event from the seismometer and used it as ground truth data to evaluate the detected event from the smart phone using the proposed design.
