M04007MT <br />the soil strength potential (internal friction angle and <br />cohesion) of remolded samples tested, <br />the natural moisture content of samples tested, and <br />the moisture-density relationship of soil samples tested. <br />- The samples tested were at differing proportions of the on site <br />clay soil material and the coal gob. <br />- Our comments, suggestions and recommendations are based on the <br />soil strength parameters encountered during our laboratory <br />study, the subsurface soil and ground water conditions <br />encountered during our 10 November 2003 Geotechnical <br />Engineering Study for the site and the proposed gob pile <br />geometry. <br />2.0 SITE CHARACTERISTICS <br />Site characteristics include observed existing and pre-existing <br />site conditions that may influence the geotechnical engineering <br />aspects of the proposed site development. <br />2.1 Site Location <br />The site is located at the Bowie Number 2 Mine located <br />approximately four (4) miles east of Paonia, Colorado. <br />2.2 Site Conditions , <br />At the time of our site visit the gob pile was constructed to <br />near one hundred (100) feet vertical with a two to one (2:1) slope <br />face. <br />2.3 Subsurface Conditions <br />The subsurface conditions for the gob pile foundation are <br />described in our 10 November 2003 Geotechnical Engineering Study. <br />2 <br />~Cam6ert anD ~,ooociates <br />CONSULTING GEOTECMNIGL ENGINEERS AND <br />N ATERIAL TESTtN6 <br />
