and shaft liner were effective in stopping groundwater from entering the
shaft. There is no flow at the bottom of the shaft.
The Hubbard Creek vent shaft has been backfilled a capped with concrete.
This backfill will protect the integrity of the grouted liner to contain the water
bearing zone. The concrete cap will ensure no surface run -off will enter the
backfilled shaft. Thus, the shaft backfill and concrete shaft will protect the
hydrologic balance.
The quality of ground water that comes in contact with coal seams and
surrounding strata is generally degraded. Bear Coal Company prepared a
study of the potential effects of mining on the B -Seam aquifer (J. E. Stover &
Associates letter to DMG dated October 23, 1995). A correlation was made
between the geochemical characteristics of the roof, coal and interburden
and the degradation of the quality of water in the coal seam. Soluble
calcium, magnesium and sodium appears to degrade the quality of ground
water that comes in contact with the disturbed coal seam and surrounding
strata. This degradation of ground water quality is considered typical for
water which seeps into the mines in the Paonia Somerset area.
The quality of springs and seeps should not be degraded by the coal mining
operation. As explained in Section 2.04.7, the primary source of water for
the springs are unconsolidated quaternary deposits. These deposits should
not be affected by the mine operation to the extent that the quality of the
spring water would be degraded.
The quantity of water in the springs and seeps could be reduced by
subsidence cracks. Subsidence cracks could intercept the impervious layer
below the springs and seeps which would cause them to drain to the
formation below.
(a)(ii) Volume 11, Map 23, Water Rights Location shows the water rights within the
permit and adjacent area. Water right map codes 1, 2, 3, 4, 5, 11, 14,15 &
32 are within the area that could be affected by mining. Map codes 1
through 5 are decreed water rights described as J & M Spring & PL No. 1 - 5.
Map code 11 is the Leonard Springs. Map code 32 is the Bowie Spring No.
3. The Operator owns water right map codes1, 2, 3, 4, 5, 11,14 & 32. Map
codes 14 and 15 are Bowie Springs 17 and 13 respectively.
