Additionally, Northfield will sample the excavation material periodically
as it is produced and placed in the bench fill. Sampling and analysis
data will be submitted to the Division and included in Exhibit AI.
Underground mining operations are designed to maximize coal
recovery and overall mine productivity, thus completing the majority of
necessary development work in the mineable coal seam. As a
consequence, no significant quantities of mine development waste will
be produced during mining operations. The limited quantities of non -
coal material resulting from the construction of overcasts or ramps can
be placed in designated underground gob or storage areas, or
transported to the surface for disposal in the waste stockpile.
The only other material to be placed in surface disposal areas at the
mine is screen plant waste product, and limited quantities coal waste
from underground construction, which will be placed in a permanent
waste stockpile located in the southwest portion of the facilities area. A
detailed discussion of screen plant waste configuration and placement
practices was previously presented in this section under the subtitle
"Mine Facilities ". The permanent waste stockpile will be designed and
constructed to insure long -term stability, provide adequate drainage,
facilitate reclamation, and maintain compliance with applicable
regulatory requirements.
The use of explosives at the Northfield Mine will occur only in
conjunction with underground mining operations. During initial
development of the mine, Northfield anticipates the use of explosives
to fragment rock while developing the slope from the surface to the
coal seam. Explosives may also be utilized within underground coal
mining operations to fragment rock in order to construct overcasts,
and to fracture resistant rock partings to facilitate coal extraction.
Given these procedures, no surface blasting is planned for the
operation and the associated regulatory requirements are not
