TABLE TWO -- FREMONT COUNTY <br />MINE NAME COMMENTS ON FEATURES `___ <br />Corley No. 6 <br />Diamond (Old) <br />Donnelly's <br />(Red Onion No. 2) <br />Double Dick <br />(New) <br />D: Operators of G.E.C. strip mine have diverted Newlin Creek northward around mine area. In <br />spring of 1980 stream broke through diversion channel and flowed into open pit. Fran there <br />it flowed into rooms of Canon National mine which had been exposed by strip mining. After <br />filling mine, water flowed out mouth of Corley ~6 mine which is 0.6 miles north of Newlin <br />Creek. Water then flowed down Second Alkalai Creek. By fall of 1980 the operators of <br />G.E.C. strip mine had stopped flow into Second Alkalai Creek by plugging entry to Corley 1~6 <br />mine. <br />S: Three subsidence pits 30' to 40' in diameter, 6' to 10' deep and 30' to 50' apart. Line of <br />Line of pits trends NW and marks former stopes in steeply dipping coal bed. Two additional <br />pits (40' diameter, 8' deep and 30' diameter, 6' deep) 100' SE of line of pits mark shafts <br />of former mine. <br />S: Three subsidence pits. First pit 40' in diameter, 6' deep is over air shaft, has fence <br />around it and is partly trash filled. Second pit 10' in diameter, 7' deep is over incline. <br />Third pit 8' in diameter, 3' deep is over room. <br />*: One inclined opening and one vertical opening. Air shaft is 35' in diameter; meets main <br />incline at depth of 25'. Main incline has an opening 9' long, 4' wide; slopes underground <br />an unknown distance. Both openings partially collapsed; neither has access deterrent. <br />S: Subsidence pits and troughs. Ten pits ranging in size frorti 10' to 50' in diameter, 3' to <br />17' in depth. Two troughs 45' and 50' long, 20' and 30' wide, 6' and 4' deep. Most of <br />pits due to collapse over rooms. <br />F: Fire being abated by OSM, under emergency action program. <br />Key to unique features symbols: Z Multiple mining zones <br />* Mine opening information <br />Reclamation and/or plans -- Table Two S Subsidence features <br />lists hazard abatement work F Mine fires <br />+ Discrepancy between two sources D Mine drainage -42- <br /> <br />
