The operator of any underground mine shall comply with the following provisions relative
to maps and surveys:
1.Scale. Each mine map shall be drawn to a scale of not more than two hundred feet to
the inch.
2.General specifications. Each map shall show the name of the state, county, and
township in which the mine is located, the designation of the mine, the name of the company
or operator, the certificate of the mining engineer or surveyor as to the accuracy and date of
the survey, the north point, and the scale to which the map is drawn.
3.Boundaries and surface lines. Every map shall correctly show the surface boundary
lines of the mineral rights pertaining to each mine and all section or quarter section lines or
corners within the same, the lines of town lots and streets, the tracks a

The operator of any underground mine shall comply with the following provisions relative
to maps and surveys:
1. Scale. Each mine map shall be drawn to a scale of not more than two hundred feet to
the inch.
2. General specifications. Each map shall show the name of the state, county, and
township in which the mine is located, the designation of the mine, the name of the company
or operator, the certificate of the mining engineer or surveyor as to the accuracy and date of
the survey, the north point, and the scale to which the map is drawn.
3. Boundaries and surface lines. Every map shall correctly show the surface boundary
lines of the mineral rights pertaining to each mine and all section or quarter section lines or
corners within the same, the lines of town lots and streets, the tracks and sidetracks of all
railroads, the location of all wagon roads, rivers, streams, and ponds, and reservations made
of the mineral.
4. Underground conditions. For the underground workings, the map shall show all
shafts, slopes, tunnels, or other openings to the surface or to the workings of a contiguous
mine; all excavations, entries, rooms, and crosscuts; the location of the escape ways, and of
the fan or furnace or other means of ventilation and the direction of air currents, and the
location of permanent pumps, hauling engines, engine planes, abandoned works, fire walls,
and standing water.
5. Separate maps. A separate and similar map drawn to the same scale in all cases shall
be made of each layer of minerals mined in any mine in this state. A separate map shall also
be made of the surface whenever the surface buildings, lines, or objects are so numerous as
to obscure the details of the mine workings if drawn upon the same sheet with them, and
in such case the surface map shall be drawn upon transparent cloth or paper so that it can
be laid upon the map of the underground workings and thus truly indicate the local relation
of lines and objects on the surface to the excavations of the mine and any other principal
workings of the mine.
6. Rise and dip of minerals. Each map of underground workings shall also show by
profile drawing and measurement, the last one hundred fifty feet approaching the boundary
lines, showing the rise and dip of the minerals.
7. Copies. The original or true copies of the maps shall be kept at the office of the mine,
and true copies thereof shall also be furnished the state geologist within thirty days after the
completion of the same.
8. Extensions. An accurate extension of the last preceding survey of every mine in active
operation shall be made once in every twelve months prior to July 1 of every year and the
resultofsuchsurvey, withthedatethereof, shallbepromptlyandaccuratelyentereduponthe
original map, and a true, correct, and accurate copy of the extended map shall be forwarded
to the state geologist so as to show all changes in plan of new work in the mine, and all
extensions of the old workings to the most advanced face or boundary of the workings which
have been made since the last preceding survey, and the parts of the mine abandoned or
worked out after the last preceding survey shall be clearly indicated and shown by colorings,
which copy must be delivered to the state geologist within thirty days after the last survey is
made.
9. Abandoned mine. When any underground mine is worked out or is about to be
abandoned or indefinitely closed, the operator of the same shall make or cause to be made a
completed and extended map of the mine and the result of the same shall be duly extended
on all maps of the mine and copies thereof so as to show all excavations and the most
advanced workings of the mine, and their exact relation to the boundary or section lines on
the surface, and deliver to the state geologist a copy of the completed map.
10. Copies furnished. The state geologist shall provide the division of soil conservation
andwaterqualitycreatedwithinthedepartmentofagricultureandlandstewardshippursuant
to section 159.5 a copy of each map and map extension received by the geologist under this
section.
