摘要

The report summarizes the objectives,design,and results of two explosive excavation experiments performed as the final phase of Project Trinidad, a comprehensive series of tests to determine the cratering properties of interbedded sandstones and shales. The experiments were performed in September 1971by the U.S. Army Engineering Waterways Experiment Station Explosive Excavation Research Laboratory. These final experiments were designed to excavate through-cuts for relocation of the Colorado and Wyoming Railroad at the Trinidad Dam and Lake Project. The first of the two experiments tested a charge array designed to break up material within a 19,000-cubic yards cut to facilitate later removal of the material by mechanical means. The concept tested was mounding, a blasting technique in which charges are positioned with respect to the horizontal ground surface rather than a vertical bench face. (Modified author abstract)
