Rock Blasting is an essential and critical tool used in mining operation in which it primary aim is to fragment the rock and expose the desired mineral from the waste rock. Ground vibration stimulated by blasting is a severe environmental issue in Sierra Leone mines. The level at which it can minimize ground vibrations has been studied by varying the ditch depth. Thus, there is a need for such research. This paper presented an integrated program case study operations on the impact of blasting on nearby structures. The computational 3D model using ANSYS LS-DYNA software was employed. In the numerical simulated 3D model, a ditch was created between the blasting hole and the structure, which was strongly anticipated to reduce ground vibration further. The results demonstrated that the reduction percentage largely depends on the ditch depth to blast hole depth ratio. At a ratio between 1.0 and 1.4, which seems practicable, the vibration was drastically reduced by 62-66 percent. The findings will help in formulating and mitigating environmental issues related to blasting.
