Foidel Creek Mine
Permit Revision for Longwall Mining in the Wolf Creek Seam - Subsidence Evaluation
ATTACHMENT A
Section 2.05.6 (6) Subsidence Survey, Subsidence Monitoring, and Subsidence Control
Plan.
(a) For underground mining activities the application shall include an inventory of all structures and
renewable resource lands which exist within the proposed permit and adjacent area.
(i) If no such structures or renewable resource lands exist, no further information need be
provided in the application under this Section.
(ii) If such structures or renewable resource lands exist, the application shall include:.
(A) A brief description of all structures and renewable resource lands which exist
within the proposed permit and adjacent area; and
(B) An appropriate map, prepared according to Section 2.10, showing the location
and configuration of structures and renewable resource lands within the permit and
adjacent area.
(b) If structures and renewable resource lands are determined to exist within the proposed permit
and adjacent area, the application shall include a description of the worst possible consequences
which subsidence, if it occurred, could have for such structures and renewable resource lands.
(i) The application shall include a determination of whether subsidence, if it occurred, could
cause material damage or diminution of reasonably foreseeable use of such structures and
renewable resource lands. This description of worst possible subsidence consequences
shall include:
(A) A brief description of pre- and post mining land uses of the permit and adjacent
area, as described pursuant to Sections 2.04.3 and 2.05.5;
(B) A brief description of subsidence related phenomena predicted to occur within
the permit and adjacent area; and
(C) A brief description of material subsidence damage or diminution of reasonably
foreseeable use of structures and renewable resource lands which could result from
the occurrence of the subsidence related phenomena described in accordance with
Section 2.05.6(6)(b)(i)(B), including consideration of the definitions and
considerations contained in Sections 2.05.6(6)(e)(ii)(A),(B), and (C).
(ii) If the description of worst possible subsidence consequences, prepared in accordance
with Section 2.05.6(6)(b)(i), determines that no material damage or diminution of
reasonably foreseeable use could result in the event of mine subsidence within the permit
and adjacent areas, and if the Division concurs with that conclusion, the application shall
include a monitoring program designed to determine the accuracy of that conclusion, as
described in Section 2.05.6(6)(c).
(iii) If the description of worst possible subsidence consequences, prepared in accordance
with Section 2.05.6(6)(b)(i), determines that material damage or diminution of reasonably
foreseeable use could result in the event of mine subsidence within the permit and adjacent
areas, the application shall include additional information as required by either one of the
following:
(A) A subsidence survey, as described in Section 2.05.6(6)(e); or
(B) A subsidence control plan, as described in Section 2.05.6(6)(f).
