Abstract
The objectives of this study were to find and describe geologic factors that influence roof conditions in underground mines. The primary method of study was detailed mapping in mines, supplemented by regional computer mapping using drill-hole data, close-range photogrammetry, physical testing of core samples, and clay mineralogical investigations of roof material. Over a period of 3 years, a large volume of data has been generated. The results are reported in two volumes. Volume 1 is a summary for general use of the major findings and conclusions; volume 2 includes a detailed account of the method of study, the data gathered, and the conclusions reached.
