    Volume II of this report (Contract No. H0122026) presents the findings of a short intensive assessment performed during the fall of 1972. This assessment provided the federal Bureau of Mines with independent technical judgments regarding the potentials and limitations of seismic methods and systems for (1) detecting the presence of isolated signaling coal miners, (2) locating such miners to within the confines of a 600- by 600-foot mine section, and (3) further locating these miners to within a 15-foot entry width. Experimental seismic data previously gathered by others during a series of mine field tests, and other relevant seismic data were fully utilized for the assessment reported in this volume.
