Explosives are used in various commercial applications including the extraction of natural resources from the earth and removal of materials for new construction. These applications include among others: fracturing of oil and gas wells, fragmentation of oil shale for extraction of kerogen content, the production of stone products from quarry sites, and highway cuts and tunnel driving. Other than for oil shale production, these activities have been ongoing for years and the techniques of explosive utilization have developed as a result of experience. It is the intent of this paper to summarize some results of laboratory and field testing conducted by the authors at the University of Maryland.
