| Organizations of all types and sizes face a range of risks that may affect the achievement of their objectives. These objectives may relate to a range of the organization's activities, from strategic initiatives to its operations, processes and projects, and be reflected in terms of societal, environmental, technological, safety and security outcomes, commercial, financial and economic measures, as well as social, cultural, political and reputation impacts. All activities of an organization involve risks that should be managed. The risk management process aids decision making by taking account of uncertainty and the possibility of future events or circumstances (intended or unintended) and their effects on agreed objectives. With that idea new ISO Standard has been drawn up. ISO 31010:2010 has been recently issued which provides a structured process that identifies how objectives may be affected, and analyses the risk in term of consequences and their probabilities before deciding on whether further treatment is required. That ISO Standard has been adapted to Open Pit Blasting Operations, focussing in Environmental effects which can be managed properly. Technique used is Fault Tree Analysis (FTA), which is applied in all possible scenarios, providing to Blasting Professionals the tools to identify, analyze and manage environmental effects in blasting operations. Also this lecture can help to minimize each effect, studying each case. This paper also can be useful to Project Managers and Occupational Health and Safety Departments (OH&S) because blasting operations can be evaluated and compared one to each other to determine the risks that should be managed in case studies. The environmental effects studied are: vibrations, flyrock and air overpressure (airblast). Also, explosives disposal is studied. Blasting operations are carried out near populated areas where environmental effects may impose several limitations on the use of explosives. In those cases where these factors approach certain limits National Standards and Regulations establish have to be applied. This paper could be most updated tool to provide guidelines for the design, implementation and maintenance of risk management processes in blasting operations. In addition, the methodology described can be used to remove or minimize environmental effects using the most modern blasting techniques are included as blast simulation, face profiling, blast monitoring tools, and others. | |
