EXPLORATIION HOLE DRILLING, MR-49
GCC proposes to drill 1 exploration hole numbered GCC-19-06, as shown on Maps
King II-005 8s King II-006A. This hole will consist of one hole drilled to just below the
A seam in order to determine coal thickness and quality.
A small cutting pit will be constructed to capture the cuttings (see drawing at
Appendix 4(4)). Cuttings pits are excavated by a back-hoe and are approximately 6
feet wide by approximately 10 feet long. The pill will be unlined and construction is
the same for all drilling methods used. Locations of the proposed hole and existing
access roads, as well as the overland access path from the existing access road to the
drill site is shown on the attached topography and drill hole locations map.
During final reclamation, the drill holes will be plugged by filling from the bottom up
to the surface with cement. The plug will be covered with like material as in road
base or topsoil depending which is present. Tracks will be raked or brushed to
remove obvious signs of activity.
Where topsoil is encountered within the area to be disturbed at a drill pad, the
topsoil will be salvaged by scraping the suitable soil horizons to the upgradient side
of the drill pad where they will be temporarily stockpiled. Topsoil will be salvaged to
the depths described in Section 2.04.9 for the soil type encountered at the drill pad.
As the time required for drilling is short, less than a few days per hole, stockpiled
topsoil will not be seeded or otherwise actively stabilized. Topsoil will be replaced,
stabilized, and reseeded after drilling, as described in the reclamation plan in Section
2.05.4.
Given the small size and temporary nature of the drill pad, GCC requests that this
area be granted SAE (small area exemption) status with regard to sediment control.
To ensure minimal impact from water erosion, the drill pad will have straw wattle
erosion "logs" installed along the downgradient side or sides of the drill pad (See
drawing in Appendix 4(4)). The straw wattles will filter any surface water runoff from
the temporary drill pad during operations and will be left in place until reclamation of
the drill pad is complete.
Drilling will be accomplished with a truck-mounted core rig accompanied by a water
truck typically of 3,000 gallon capacity; a flat-bed service truck; and smaller pickup
trucks as necessary for service and transportation to and from the drilling site. Water
will be provided to the drill sites from the mine supply at the main plant.
The hole may be geophysically logged. The equipment necessary for such work is
typically mounted in a full-size Suburban-type 4X4. Under this program no roads are
proposed for construction and no blasting will be performed.
The moderately rugged terrain of the proposed exploration area consists primarily of
the mesas drained by Hay Gulch. Drill site elevation is approximately 7,500 feet. The
hole will be drilled on the mesa top.
