Ohio Revised Code Title XV. Conservation of Natural Resources § 1567.05

No person, except employees of the mine and those permitted by law, shall enter any mine or go upon the property connected therewith, unless the consent of the owner, lessee, or agent has been secured, and then only when accompanied by a guide furnished by such owner, lessee, or agent. This does not prohibit persons seeking employment at such mine, or the authorized representatives of the employees, from entering upon the property as is necessary to make such application to the proper authority or to transact business, if such persons do not enter the mine until given permission to do so, and do not stand on the tracks or go near the machinery or other places of danger.
