<br /> <br />SCOPE <br />This report presents the results of a preliminary geotechnical evalua- <br />tion for a proposed coal processing waste disposal area for Empire Energy <br />Corporation's No. 5 and No. 9 Mines, located near Craig, Colorado. The <br />report presents a description of surface and subsurface conditions exist- <br />ing at the site at the time of our investigation, our estimates of the <br />performance of foundation soils and bedrock, and recommendations for design <br />and construction of the proposed waste disposal facility. The report was <br />prepared based on conditions encountered in the field, results of laboratory <br />tests, and our experience with similar conditions. <br />PROPOSED CONSTRUCTION <br />Empire Energy Corporation presently has two active m=ines known as <br />"Mines No. 5 and No. 9" which are about seven miles south of Craig, <br />Colorado on Colorado Highway No. 13. We understand continuous mining methods <br />are being used which produce coal which requires processing. We understand <br />the coal will be treated by a device known as a "Bradford Breaker". Par- <br />titles entering the treating device will range in size from 5 inches to 2 <br />inches. It is our understanding that particles smaller than two inches will <br />discharge through the device and the larger, coarse and harder particles <br />will be discharged into the waste disposal area.4The material to be disposed ` <br />of will predominantly be fragments of shale, sandstone and claystone ranging <br /> <br />
