This report contains a state of the art review of current methods for evaluating the effects of close in blasting on pipelines. The report includes a comparison of current methods for determining the stress resulting from blasting with available experimental results. It also covers the subject of block movement as a result of delayed gas pressure, methods to determine the likelihood of ground movement and procedures for evaluating if movement has occurred. More accurate methods to determine blasting stresses are investigated. A procedure to be followed to evaluate the effects of blasting is proposed....

The report includes a comparison of current methods for determining the stress resulting from blasting with available experimental results. It also covers the subject of block movement as a result of delayed gas pressure, methods to determine the likelihood of ground movement and procedures for evaluating if movement has occurred. More accurate methods to determine blasting stresses are investigated. A procedure to be followed to evaluate the effects of blasting is proposed. Finally, recent developments in blasting technology that are relevant to blasting near pipelines are reviewed.
