PROPOSED GEOTECHNICAL FINDINGS
COAL RIDGE N0. 1 COAL MINE
Rule 2.05.3(2) Operations Description
In response to Division adequacy comment, requesting amendment to more
adequately address the proposal of several escapeways and raises daylighting
at the outcrop high on the Grand Hogback's northeast-facing slope, the
applicant has provided additional description of the planned facilities on
pages 4-26 and 4-26a of the amended application. The applicant has amended
page 4-26a to include a commitment to submit designs and acquire design
approval, before constructing either of the two future escapeways or
ventilation raises depicted on amended Figure 4.2-4.
Rule 2.05.3(6)(a) Use of Explosives
In response to Division adequacy comment, requiring appropriate submittal in
response to the requirements of Rule 2.05.3(6)(a)(i) through (vii), the
applicant submitted additional information. The amended application's pages
4-63 through 4-63e satisfy the above referenced requirements. Storm King
Mining, Inc. has indicated a proposed explosives bunker location on Figure
4.2-3 of the amended application.
Storm King Mining has included commitments to conduct pre-blasting surveys of
all structures within Riverbend Subdivision, prior to conducting any blasting
operations at the site (page 4-63a). Further, the applicant commits, in their
second response letter, to perform pre-blasting surveys for any structure
within the "general proximity of the blasting area", outside the strictly
required one half mile limit.
Rule 2.05.3(8) Coal Processing and Non-Coal Processing Waste
In summary, the applicant has submitted the majority of the information
required to comprise a "general plan" for a coal processing waste embankment,
as described in Rule 2.05.3(S)(a), to be constructed as a portion of Phase B
of the proposed life-of-mine operations. Amendment of the design to yield the
required seismic safety factor would render the general plan technically
adequate. The applicant has not, however, completed a "detailed design plan",
as described in that same rule.
The applicant amended the originally proposed mine plan to divide the plan
into two Phases, A and B. Phase A includes the development of a test mine,
without the permanent coal processing waste slurry embankment. The applicant
has amended pages 4-15d and 4-15e to describe the temporary stockpile storage
of coal processing waste in the stockpile area adjoining the raw coal
stockpile. The applicant projects 2% waste, based upon analysis of the
resource drilling performed on the coal seam to be mined. A total of 600,000
