50-73-208. Final survey and map update when mine abandoned or worked out. (1) When a coal mine is worked out, is about to be abandoned, or indefinitely closed, the operator shall make or cause to be made a final survey of all available parts of the mine, and the results shall be duly extended on all maps and copies of the mine to show all excavations and the most advanced workings of the mine and their exact relations to the boundary or section lines on the surface.
(2) The department may order a survey to be made of the workings of a mine which is about to be abandoned or of which it has reason to believe the maps are inaccurate whenever in its judgment the safety of the workers, the support of the surface, the conservation of the property, or the safety of an adjoining mine requires it. The survey shall be at the expense of the state.
