M03106GE <br />1.0 INTRODUCTION <br />This report presents the results of the <br />study we conducted for the proposed Bowie <br />near Paonia, Colorado. The study was con <br />Mr. Collin Stewart, P.E., Bowie Resources <br />our proposal for geotechnical engineering <br />2, 2003. <br />geotechnical engineering <br />Number 2 Mine gob pile <br />3ucted at the request of <br />LTD, in accordance with <br />services dated September <br />The conclusions, suggestions and recommendations presented in <br />this report are based on the data gathered during our site and <br />laboratory study and on our experience with similar soil condi- <br />tions. Factual data gathered during the field and laboratory work <br />are summarized in Appendices A and B. . <br />1.1 Proposed Construction <br />It is our understanding that the proposed gob pile will be about <br />two hundred thirty (230) feet high and will be constructed at an <br />inclination of about two (2) to one (1) (horizontal to vertical). <br />The slope face will include three (3) benches across the slope face <br />about fifteen (15) wide and one (1) haul road about twenty (20) <br />feet wide. The gob pile will be constructed using waste material <br />from the coal mine and the coal wash plant. <br />The gob pile development will include a topsoil storage pile and <br />a cover material storage pile. The topsoil storage pile will be <br />about orie hundred eighteen (118) feet high and constructed at an <br />inclination of about two (2) to one (1) slope. The cover material <br />storage pile will be about seventy five (75) feet high and con- <br />structed at an inclination of about two (2) to one (1). <br />1.2 Scope of Services <br />Our services included geotechnical engineering field and labora- <br />tory studies, analysis of the acquired data and report preparation <br />for the proposed site. The scope of our services is outlined <br />below. <br />- The field study consisted of describing and sampling the soil <br />materials encountered in fourteen (14) small diameter continu- <br />ous flight auger advanced test borings at the proposed gob pile <br />location. <br />- The materials encountered in the test borings were described <br />and samples retrieved for the subsequent laboratory study. <br />i <br />~tam6ert ana ~,~,~otiate,~ <br />CONSULTING GEOTEDNNICAL ENGIN EER9 AND <br />MATERIAL TESTING <br />
