| Abstract |
An engineering and economic evaluation of explosive casting defined as the use of blasting to move overburden to a spoil pile without handling was made. A series of design nomograms relating the geometry of blast rounds to properties of intact rock and the range over which material is cast were developed, and serve as a design hypothesis for future studies of the method. Economic evaluation indicates the method can be used to advantage for mining operators capable of increasing production which more than offsets the added cost of drilling and blasting. The method also has application when confronting an increased stripping ratio. While preliminary assessment is made of environmental and regulatory impacts, additional studies are required to demonstrate technical and economic feasibility. (ERA citation 04:017762) |
