A concept of blasting termed 'mounding' involves using relatively compact explosive charges and breaking to the horizontal ground surface. Project Lost Creek comprised a group of single-charge and row-charge blasting experiments designed to investigate the concept of mounding. Mounding-row design criteria, fragmentation produced by mounding charges, and performance of mounding explosives with differing properties were studied, as were suitability of mounding for producing rock fill and use of controlled blasting in conjunction with mounding charges to diminish shock and to improve excavation slope control.
