Presently four main seams are recovered. They are the "H", 'I", "Q" and "R" seams. Later, other seams may be recovered. When predicable, any rider seams ere also recovered. (Refer to Section 2.7.1 for a more detailed discussion of the coal seams recovered.) In some cases, pit dewatering of open cuts will be performed using portable pumps. In addtlion, dewa- tertng wells may be installed at the north end of the pit cuts and in front of the advancing active mining area. The wells are constnrded no more than ten feet below the lowest mineable coal seam and may be pumped prior to the beginning of actively "opening up• the area. Appropriate well permits have been filed (Section 2.7.5.4) and provide Trapper the legal right to construct and pump these wells. Appropiete records are kept cenceming the wlume of water pumped from the open pit cuts and drilled wells. The mining methods employed at the Trapper Mine effectively conserve and util¢e the opal resource. Coal is recovered to the maximum depth that present equipment and economic limits wdl albw. This endeavor minimizes the possibility of remining the area by surface methods and results in a program that maxlmaes coal recovery and minim¢es surface disturbance. 3.1.4.1 MlnlnO Sequence Ashmore Pil Mining Area In May 1997, the Queen Anne dregline walked from Hawken pR to Ashmore pk (A-pit) to replace the Baby Doe dregline as the primary stripping machine for this area. Mining will continue to advance to the east in the Sage drainage and extend into the Oak watershed. The dregline reaches an area on the west side of the Oak drainage in the latter part of 1999 and will walk to the east side of the gulctr to open a • boxcut. This new area will be referted to as Ashmore East pit. Refer to the M10 series maps for a yearly detail of the mining and redamation sequences for the 199&2002 permit term. Ashmore East Pit Mining Area Mining in Ashmore East pit (A-East pR) will begin in the latter part of 1999. After completing the cuts in Ashmore pit, the Oueen Anne dregline will open a boxcut on the east side of Oak drainage. Mining will _-_-- advance to the east into Flume Gulch until R reaches the eastern mining limits in early 2002. The-.,_,,.. dregline will then move north to open a boxcut in Gatling Pit. Refer to the M10 series maps for a yearly detail of the mining and redamation sequences for the 1998-2002 pemtil term. Ashmore South Pd Mining Area Scrapers began removing the I-seam overburden in an expansion area south of Ashmore pit in April 1997. The expansion area, referted to as Ashmore South pit (A-South pit), was approved wdh MR-153. After being replaced by the Queen Anne dregline in Ashmore pit, the Baby Doe dregline opened a lwxcut '"`'""` in Ashmore South pit. After advaridhg to the east for three cuts, the dregline walked to Ffadbdcpit•in~.~=•.••• September 1997. Upon completion of the third cut, the Ashmore South area is scheduled to remain idle until the beginning of 2002. At that time, the Moly Brown will walk from Dertinger pR to resume mining operations in this area. However, when mining resumes, the area will be referted to as FGntbck East pit. Refer to the M70 series maps for a yearly detail of the mining and redamation sequences for the 1998- 2002 permit term. Dertinger Pit Mining Area Derringer pit (D-pit) mining will continue advandng to the east in No Name drainage urrbi it buffs up • against the open cut in Enfield pR at the end of 2001. The Molly Brown dregline will then wa0c from D-pit to Flintlock Easl pR where ft will reactivate the area contiguousy to the east of Ashmore South pit. Refer. . to the M70 series maps for a yearly detail of the mining and redamation sequences for the 1992002 permit term. - - 3-1s _ - `~ MAY 1 3 1998 Pe-`f
