M03107GE <br />- The field study consisted of describing and sampling the soil <br />materials encountered in three (3) small diameter continuous <br />flight auger advanced test borings at the proposed Coal Pro- <br />cessing Facility location. Site conditions somewhat restricted <br />the number and locations of the test borings. <br />- The materials encountered in the test borings were described <br />and samples retrieved for the subsequent laboratory study. <br />- The laboratory study included tests of select soil samples <br />obtained during the field study to help assess: <br />the soil strength potential (internal friction angle and <br />cohesion) of samples tested, <br />the swell and expansion potential of the samples tested, <br />the settlement/consolidation potential of the samples <br />tested, <br />the moisture content and density of samples tested and <br />the soil sulfate concentration of soil samples tested. <br />- This report presents our geotechnical engineering comments, <br />suggestions and recommendations for planning and design of site <br />development including: <br />viable foundation types for the conditions encountered, <br />allowable bearing pressures for the foundation types, . <br />geotechnical engineering considerations and recommendations <br />for concrete slab on grade floors, and <br />geotechnical engineering suggestions and recommendations for <br />cut and fill slope stability. <br />- Our comments, suggestions and recommendations are based on the <br />subsurface soil and ground water conditions encountered during <br />our site and laboratory studies. <br />- Our study did not include any environmental or geologic hazard <br />issues. <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 proposed coal processing site is located at the Bowie Number <br />2 Mine located about four (4) miles east of Paonia, Colorado.
