• 4.09 DISPOSAL OF EXCESS SPOIL AND UNDERGROUND DEVELOPMENT WASTE
The development of the Bear No. 3 mine has had two separate
occasions when a substantial amount of Gob was produced. The first
was during the initial development of the mine when the entries of
the Old Edwards Mine were cleaned up for future use. The gob
developed during this clean up operation was stored in the
abandoned workings of the old mine. This storage area is shown on
the Mine Plan Map (Map 9).
The second was in mid 1989 when the declines were driven from the
C-Seam to the B-Seam. The qob developed from the declines was
transported to the surface to a temporary gob storage area and then
finally disposed of at a gob disposal area at the Somerset Mine.
The Bear No. 3 Mine is not expected to produce any significant
amount of gob in the future. One significant reason for this is
the fact that the roof in the B-Seam is competent and not subject
to spalling and roof falls like the roof in the C-Seam. Minor
amounts of gob produced underground will be stored underground with
MSHA's concurrence or hauled to the surface and transported to an
approved gob disposal area at a regional mine. The Operator will
obtain approval from the Division prior to hauling gob to a
regional mine.
If necessary, gob is transported from the underground workings by
• an underground scoop and placed in a temporary pile near the
portal. The gob is then rehandled by the surface front-end loader
and placed in the designated temporary gob disposal area shown on
the Mine Facilities Map, Map 10. The temporary gob pile perimeter
will be kept well away from the haul road loop to prevent tracking
gob material onto the road system. Certain conditions such as
inclement weather or winter weather may preclude access to a
regional mine's qob pile for an extended period of time.
Therefore, the gob may be temporarily stored in the designated area
for up to 30 days before it is hauled to an approved gob disposal
area. Up to 1500 tons may be temporarily stored in the gob storage
area at any time.
The Operator will keep a file at the mine office which will
document the date and amount of gob transported to the approved gob
disposal area. The records will show the regional mine to which
the gob was transported. A summary of this gob disposal informa-
tion will be transmitted quarterly to the Division.
