انفجار در حفاری‌های زمینی و معادن

Basic theory and existing methods are presented, with both empirical and analytical models. The authors discuss parameters influencing mine and ground excavation operations, statistical formulae used in the analysis of field data, generation and prediction of ground vibration from opencast blasting, threshold limit of ground vibration for safety of surface structures, influence of blasting on surface and underground workings, and rock fragmentation due to blasting. Includes many tables and figures. No index. Annotation copyright Book News, Inc. Portland, Or. Discussing blasting in ground excavations and mines, this text covers basic principles, usual techniques, significant variables, optimum design aspects, modifications of some physical concepts in the context of mine and ground excavations.
