PURPOSE AND SOOPE OF STUDY <br />• This report presents the results of a geotechnical investigation <br />for the Deserado Coal Mine coal refuse disposal areas located in <br />Secs. 22, 23, 26 and 27, T. 3 N., R. 101 W., approximately 15 miles <br />northeast of Rangely, Colorado. The project location is shown on <br />Fig. 1, and a vicinity map showing the location of the disposal area <br />is shown on Fig. 2. The study was conducted in accordance with our <br />proposal to Ford Bann & Davis Utah, Inc. dated October 29, 1980. <br />A field exploration program was crorducted to obtain information <br />on subsurface conditions. Samples of the material obtained during the <br />subsurface investigation were tested in the laboratory to provide data <br />on the engineering characteristics and classification of the on-site <br />soil and rock. The results of the field and laboratory investigations <br />• are presented in Appendices A and B, respectively. <br />The report has been prepared to summarize the data obtained and <br />present our conclusions and reocmnendations based on the conditions <br />encountered. Design parameters and a discussion of geotechnical <br />engineering considerations related to construction of the proposed <br />facility are included. <br />PPDPOSED OJNSTRUCPION <br />The Deserado Coal Mine will be a 2 million ton per year <br />underground mine with related surface processing and transportation <br />facilities. Coal will be mined underground and transported to surface <br />facilities at the D Fbrtal for crushing, screening and washing. Waste <br />materials from the washing process will be transported on a haul road <br />• to the subject coal refuse disposal area (Fig. 2). <br />
