PEC 99 '97 12~09PM ARCG COAL CO GEN`-ER <br />Dave Beny <br />December 9, 1997 <br />Page 4 <br />22. MCC's PHC explicitly defines probable water movement within and <br />discharge locations at and in the vicinity of the Bear Mine. Does Sear and <br />its consultant agree with MCC's interpretation? If not, please provide us <br />with your alternative explanation. <br />23. Are there any connections between the old Edwards/Clark Mine and the <br />Bear mine workings? <br />24. Does Bear Coal Company have information (i.e., maps) showing the extent <br />of the Edwards/Clark mine workings? Can MCC get a copy of this <br />information? <br />25. Where is the minimum overburden thickness within the Bear mine workings? <br />26. What is the minimum distance between the Bear mine workings and the <br />~ Edwards/Clark mine workings and where is it located? <br /> <br />27. Does water quality data from bedrock monitoring wells at the Bear Mine <br />show similar characteristics to the water discharging from the Edwards/Clark <br />Mine? <br />28. Does Bear Coal Company have reason to believe that groundwater within <br />the EdwardsfClark Mine would have elevated temperatures or conductivity <br />values? <br />29. When was water first encountered in the Bear No. 3 Mine, in which seam <br />and where? <br />30. What type of extraction method (e.g., complete extraction, split-and-fender, <br />etc.) was used in the Bear No. 3 Mine, in the B-Seam, and in the C-Seam? <br />31. Did landslides effect mining operations in either the 6-Seam or C-Seam? <br />32. Were roof instability problems encountered in the Bear No. 3 Mine, B-Seam <br />and C-Seam? ff so, what type of problems were encountered and where? <br />P.Si7 <br />33. Produce mine maps showing faults, fractures, location, timing and amount <br />and temperature of encountered water in B-Seam and C-Seam in the Bear <br />Mine. Where was mine water stored prior to or in lieu of discharging it to the <br />surface? <br />34. Provide location and areas where C-Seam workings collapsed into the B- <br />Seam workings. <br />35. Provide location and character of all seals placed in B- and C-Seam <br />workings. <br />
