<br /> <br />• Q~ 35. <br />Is the location and elevation for the DH series of drill holes the only information <br />available? <br />36. The Division current understanding of the coal seams to be mined by the surface mine <br />t ~ are, in descending order, R, Q, P, O, O„ and the N. Underground mining will occur in <br />j~ ,r'~ the R and the Primero, the lowest seam to be mined. Alt seams to be mined should be <br />1 ~Gt ~~a depicted on Figwe G-I, Representative Columnar Section and list ranges of thickness <br />~L ~' Jr~ ~ whtch agree with the corresponding text.

No mention is <br />oy '. <br />~IYt I, `a`1 made of the R and the O, and furthermore, the seams aze listed out of sequence.

However, Figwe G-1 indicates neazly 700 feet of sepazation. <br />Which is correct? Inaccwate information should be removed or corrected. <br />The Geology Map 2.04.6-2 provides information for the R and P seam for the swface <br />mine and the C and P seam for the underground operation. Are the R and the C seam <br />the same seam while the P and P seam are different? Other information references the <br />Ciruela seams, which is appazently the R. The Division has no preference on which seam <br />name is used as long as it is onsistent oIn all permit. materials. Pease correct and/or <br />clarify. ~~~\ ~k Y;~~~ ~ S-h ~~ ~e C C~'" 1[oYCn-vC a~w.a,.r /n w'3 <br />P ~- ~ w-S <br />Why aze there substantial differences in the zero contow on Overbwden Thickness map <br />G-1 and the coal outcrop of the Ciruela seam on map G-2?
