Book Description
Experiments were conducted to investigate a concept of limiting some adverse effects of using explosives to break rock. Specifically, it was hypothesized that a planar zone of explosively fractured rock might attenuate the stress wave generated by an explosive charge, and thereby serve to protect a structural plane, such as a presplit surface, from damage. The zone of explosively fractured rock has been designated a buffer zone. The overall concept would be to place buffer zones between structural rock surfaces and the main excavation charges. Peak particle velocities generated by 200-lb, deeply buried cratering charges were measured both with and without the presence of intervening buffer zones. The results were not conclusive as to the effectiveness of buffer zones, and improved experimental procedures may be required in further investigations. (Modified author abstract).

Book Description
Field work, supplemented by laboratory studies, is a cornerstone for the geological sciences. This volume provides an introduction to general field work through selected topics that illustrate specific techniques and methodologies. One hundred and twenty-three main entries prepared by leading authorities from around the world deal with aspects of exploration surveys, geotechnical engineering, environmental management. field techniques, mapping, prospecting, and mining. Special efforts were made to include topics that consider aspects of environmental geology in particular those subjects that involve field inspections related to, for example, the placement of artificial fills, sediment control in canals and waterways, the geologic effects of cities, or the importance of expansive soils to environmental management and engineering. In addition, some widely ranging topics dealing with legal affairs, geological methodology, the scope and organization of geology, report writing, and other concepts, such as those related to plate tectonics and continental drift, provide a necessary perspective to the arena of field geology.
