NMD (Panels 12 -Right through 16- Right, PR 99 -05)
<br />TCC will continue to mine the reserves it controls in the Twentymile Park Basin. The mine moved operations into
<br />• the NMD as shown on Map 23, Mine Plan Map. TCC controls all of the coal required to mine in this area. TCC
<br />projects annual coal production at up to 10 million tons per year.
<br />TCC uses the longwall mining method as the primary technique for assuring maximum recovery of the resource. In
<br />the NMD, plans call for a 1,000 -foot wide face, with panel lengths ranging from approximately 13,600 to 17,000
<br />feet. The gate- roads, main and sub -mains will be developed by continuous miner, as is the current practice.
<br />NMD (14 -Right Gate -road Alternate Location, MR O1 -171)
<br />TCC evaluated whether or not the 1,000 -foot wide face could be increased to approximately 1,200 feet or wider. In
<br />general, the outcome of the evaluation limited the face width to something less than 1,200 feet. In order to
<br />accommodate the uncertainty associated with this evaluation, and initiate the start of the gate -road, an area is shown
<br />in red on Map 23 and 23 B for potential areas in which the 14 Right Gate -road will be started.
<br />NMD (Panels 17 -Right through 21- Right, PR03 -06)
<br />The mine continues its operation into the NMD as shown on Map 23, Mine Plan Map. TCC has projected annual
<br />coal production to increase from the current levels to a maximum of approximately 12 million tons per year.
<br />TCC uses the longwall mining method as the primary technique for assuring maximum recovery of the resource. In
<br />Panels 17- through 21- Right, mining continued in the NMD during this permit term with a 1,000 -foot wide panel
<br />and panel lengths ranging from approximately 10,900 to 15,700 feet. The gate - roads, main and sub -mains were
<br />developed by continuous miner, as is the current practice.
<br />• NMD (Panels 21 -Right through 24 -Right (24 -Right Partial), PR06 -07)
<br />The mine will continue its operations to the geologic /economic limits of the NMD as shown on Map 23, Mine Plan
<br />Map. TCC projects ongoing annual coal production of up to approximately 12 million tons per year.
<br />TCC uses the longwall mining method as the primary technique for assuring maximum recovery of the resource. In
<br />Panels 21- through 24- Right, mining will continue in the NMD during this permit term with a 1,000 -foot wide
<br />panel and panel lengths ranging from approximately 9,500 to 15,700 feet. The gate- roads, main and sub -mains will
<br />be developed by continuous miner, as is current practice.
<br />WESTERN MINING DISTRICT (WMD)
<br />WMD (Panels 12- through 20 -Left, and 13- and 14 -Left Inby, PR06 -07, PR09 -08, TR07 -63, TR08 -64, TR09-
<br />68, TR09 -71)
<br />TCC will continue to mine the reserves it controls in the Twentymile Park Basin. Preliminary (Phase 1)
<br />development of the WMD was initiated under PR06 -07 and TR07 -63 to facilitate extension of mine ventilation and
<br />support facilities for both the northern portion of the NMD, and the new WMD into the Northern Mining District as
<br />shown on Map 23, Mine Plan Map. TCC controls all of the coal required to mine in these areas. TCC projects
<br />annual coal production at up to 12 million tons per year. In preparation for future mining in the WMD, TCC has
<br />proceeded with initial (Phase I) Phase II, and Interim Phase III development of the main and sub -main entries for
<br />Panels 13 -Left through 17 -Left, as shown on the Mine Plan Map, Map 23. Phase I through Interim Phase III
<br />development will result in extension of development in the 18 -, and 17 -Left gate -roads to their furthest western
<br />limit, partial development of the 16 -, 15 -, 14, and 13 -Left gate- roads, and full development of the 97' and 10 -North
<br />• Mains. Development of the 18 -, and 17 -Left gate -roads will extend into the new Federal coal lease (COC- 72980)
<br />at the western edge of the WMD. Full development and longwall mining under PR09 -08 will extend development
