on Map 22 Mine Progress Map. Surface facilities associated with the underground
mining are shown on Maps 11, Sheets 1 -3 and Map 12. Future mining is subject to
conditions encountered.
Mining is currently planned for 2011 -2015 within the area bounded by the permit
boundary as shown on Map 3 -20'11 Mine Plan. Mining for 2011 -2015 is anticipated
to occur in the Allen seam north of the Purgatoire River and East to the permit
boundary. Mining is planned in the Apache seam south and east of the East Portals.
Mining in the Allen and Apache Seams will not overlap except where the Apache
Seam must cross over old Allen seam workings. Blue Seam mining will proceed east
to the permit boundary and then turn south. Continued development and operations
of the New Elk Mine within the lease area will require additional permit revisions to
complete full recovery of the coal reserve. Minor additional surface disturbance may
be associated with the continued operation of the mine. This surface disturbance, if
required, will provide for ventilation and escape ways as development progresses
away from the main portal area to maintain continued production and safe working
conditions. The total affected area based on the TR -58 mine plan and historic mining
is 3,799.5 acres. The permit boundary totals 4,199.5 acres. Long -term mine plans are
shown on Figure 2. Life of mine acreage as shown on Figure 2 totals approximately
19,050 acres. Future revisions to the permit may propose mining in the Maxwell
seam.
2.05.3 Operation Plan- Permit Area
The planned underground workings are show on Map 3 -2011 Mine Plan. The
generalized stratigraphy of the Allen, Apache and Blue Seams are shown on Figure
1. The mine was temporarily closed and sealed in 1989. Dewatering ceased and the
lower areas of the mine were gradually flooded.
Phase 1 of resuming operations required remotely pumping mine water from the East
Portal airshaft and other boreholes using surface - powered pumps. Approvals for this
process were granted in 2008 and dewatering started in December of 2008. Phase II
re- establishes mine ventilation by breaching temporary seals at the East and West
Portals and Apache Canyon, and reinstallation of fans at the East Portal and West
Portal airshafts. Phase III is the development of entries to establish ventilation at the
Apache Seam level. Phase IV is the active mining of coal.
The planned development of mains and panels will occur as shown on Map 3 2011
Mine Plan. Development of main access entries north and south of the portals will
begin upon completion of the connection to the East Portal airshaft. Mining in the
Allen Seam will advance north and east of the slopes. Mains will be developed north
off the slope bottom ramping down to the Allen Seam after crossing over old Allen
works. The mains will be extended through the Allen Seam to the east and north.
Panels will be driven off the mains, one panel to the east and four panels to the west.
The Allen Seam mining is development only. No pillar recovery is planned in the
Allen seam works.
