State Req. <br />OPERATION PLAN <br />Peabody Coal Company proposes to auger both the Lennox and Wadge coal <br />seams and strip mine the Lennox coal in the area as shown on Exhibit 12-I. <br />At the present time, approximately one-third of the L-shaped pit is open and <br />ready for the augering operation. The area labeled Pit "C" has already had <br />the Wadge coal removed by roger mining methods. The auger machine is <br />presently working in Pit "B:' The narrowness of the bottom of the pit is <br />hampering auger operations. The auger machine needs to move to Area "E" <br />in order for Pit "B" to be cleaned up to facilitate the final augering of coal <br />from that pit. <br />Angering in Area "E" will start in the eastern end on the Wadge coal seam. <br />Once augering has reached the western end of the east-west open pit <br />removal of the overburden above the Lennox coal seam can commence. <br />Strippable Lennox shows up at about the 16,000 E grid line and then con- <br />times west and north. Lennox east of this line is either too soft or smutty <br />due to the close proximity of the cropline. Once the overburden is removed,. <br />the Lennox coal will then be loaded out by conventional methods. Removal <br />of the Lennox creates a bench for the auger machine to operate from to <br />then auger mine the Lennox coal seam. Please refer to Figure MR17-2 for <br />typical augering patterns. <br />Production -Area "E" <br />Peabody Coal Company has found that recovery rates in areas angered thus <br />far are just over 40 percent of the total available reserves. This figure falls <br />in line with estimated recovery rates from various published reports. <br />Production for this area will total approximately: <br />Lennox <br />10.54 acres <br />4.4 feet thick (average) <br />1640 TPAF <br />76,100 tons (total) <br />12-s-10 <br />
