Today blasting has become an acceptable technique for rock breakage worldwide. Easting towards large opencast mines from traditional underground methods to cope with high production target demands for planning and executing blasts with large diameter holes and high explosive charges. Such a large size blast, it not properly designed and attended, may result in ground vibration, fly rock, air overpressure etc. endangering the safety of personnel and property and cause nuisance to the habitats. Blast area security and fly rock from surface blasting operations is one of the potential threat to the safety, witnessing for over 60 percent of all blasting-related injuries in surface coal, metal, and non-metal mines, therefore responsible blasting requires that rock throw be controlled to ensure that no danger will result to people and property. This paper presents a brief account of injuries due to fly rock and lack of blast area security in surface mines, an overview of fly rock problem and elucidates mitigation techniques.
