INTRODUCTION
The movement of rock masses became central to the implementation of major projects such as tunnels, roads and dams. The importance of quality, safety and environment, becomes essential from the beginning to the end of each project to ensure the least impact on the surrounding environment, people and goods. It is already common practice in geotechnical studies to use explosives in areas with several constraints, causing potential environmental impacts in particular vibrations in structures. The operation of rock blasting moves rock masses.
This often causes various side effects affecting directly the surrounding environment and sometimes restricting and hindering the implementation of projects. Based on this it becomes essential to find a method of recording and quantifying the side effects caused by the use of explosives. This approach will register the velocity of vibration caused on the ground after the detonation, which will serve to evaluate and anticipate side effects and possible damages occurring while performing the work. Standard scaling laws of charge weight are used commonly in the prediction at ground level.
