Sec. 1.5. (a) The operator of a coal mine shall have, in a fireproof
repository located in an area on the surface of the mine chosen by the
mine operator to minimize the danger of destruction by fire or other
hazard, an accurate and up-to-date map of such mine drawn on scale.
Such map shall show:
(1) the active workings;
(2) all pillared, worked out, and abandoned areas, except as
provided in this section;
(3) entries and aircourses with the direction of airflow indicated
by arrows;
(4) contour lines of all elevations;
(5) elevations of all mine and cross or side entries;
(6) dip of the coalbed;
(7) escapeways;
(8) adjacent mine workings within one thousand (1,000) feet;
(9) mines above or below;
(10) water pools above; and
(11) either producing or abandoned oil and gas wells located
within five hundred (500) feet of such mine and any
underground area of such mine; and
(12) such other information as the director may require.
The map shall identify those areas of the mine which have been
pillared, worked out, or abandoned, which are inaccessible or cannot
be entered safely and on which no information is available.
(b) The operators of adjoining coal properties must leave, or cause
to be left, a pillar of coal fifteen (15) feet in width on each side of the
property line in each seam or vein of coal worked by them.
(c) The following additional information shall be shown on mine
maps:
(1) Name and address of the mine.
(2) The scale and orientation of the map.
(3) The property or boundary lines of the mine.
(4) All drill holes that penetrate the coalbed being mined.
(5) All shaft, slope, drift, and tunnel openings and auger and
strip mined areas of the coalbed being mined.
(6) The location of all surface mine ventilation fans, the
location of which may be designated on the mine map by
symbols.
(7) The location of railroad tracks and public highways leading
to the mine, and mine buildings of a permanent nature with
identifying names shown.
(8) The location and description of at least two (2) permanent
baseline points coordinated with the underground and surface
mine traverses, and the location and description of at least two
(2) permanent elevation bench marks used in connection with
establishing or referencing mine elevation surveys.
(9) The location of any body of water dammed in the mine or
held back in any portion of the mine. However, such bodies of
water may be shown on overlays or tracings attached to the
mine maps used to show contour lines as provided under
subdivision (12).
(10) The elevations of tops and bottoms of shafts and slopes,
and the floor at the entrance to drift and tunnel openings.
(11) The elevation of the floor at intervals of not more than two
hundred (200) feet in:
(A) at least one (1) entry of each working section, and main
and cross entries;
(B) the last line of open crosscuts of each working section,
main and cross entries before such sections, and main and
cross entries that are abandoned;
(C) rooms advancing toward or adjacent to property or
boundary lines or adjacent mines; and
(D) the elevation of any body of water dammed in the mine
or held back in any portion of the mine.
(12) Contour lines passing through whole number elevations of
the coalbed being mined. The spacing of such lines shall not
exceed ten (10) foot elevation levels, except that a broader
spacing of contour lines may be approved by the director for
steeply pitching coalbeds. Contour lines may be placed on
overlays or tracings attached to mine maps.
(d) The accuracy and scale of mine maps shall be as follows:
(1) The scale of mine maps submitted to the director shall not
be less than one hundred (100) or more than five hundred (500)
feet to the inch.
(2) Mine traverses shall be advanced by closed loop methods of
traversing or other equally accurate methods of traversing.
