M98177GE <br />1.0 INTRODUCTION <br />This report presents the results of the geotechnical engineering <br />study we conducted for the proposed Coal Conveyor System for the <br />Bowie Number 2 Mine east of Paonia, Colorado. The study was <br />conducted at the request of Mr. Glenn Schueler, Manager, Engineer- <br />ing and Technical Services, Savage Industries Inc., in accordance <br />with our proposal for geotechnical engineering services dated <br />September 20, 1998. <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 proposed construction will include <br />downhill conveyor system to transport coal from the mine portal to <br />~. the truck loadout area. The conveyor system will include a truck <br />load out surge bin, a reclaim tunnel, a stacking tube, a downhill <br />conveyor, and a conveyor transfer station. <br />The truck load out surge bin will be supported on four (4) <br />columns and will be about twenty-six (26) to thirty (30) feet in <br />diameter with a coal capacity of about four-hundred (400) tons. <br />The reclaim tunnel will be a corrugated metal pipe about four- <br />hundred (400) feet in length and about fourteen {14) feet in <br />diameter. <br />a <br />The stacking tube will be located in the central portion of the <br />reclaim tunnel and will be about fourteen (14) feet in diameter and <br />about one-hundred ten (110) feet high to feed a stockpile area. <br />The stockpile area will have a storage capacity of about 350,000 <br />tons. <br />The downhill conveyox will transport coal from the transfer <br />conveyor to the stacking tube and will discharge at top of the <br />stacking tube or directly onto the ground in the stockpile area. <br />The transfer station will transfer the coal from the transfer <br />conveyor to the downhill conveyor.
