underground mining equipment.

(1) After June 16, 1972, no machinery powered by an internal combustion engine shall

be placed in use in underground workings unless the equipment is rated

"permissible" as described in KRS 352.010 for underground use, and the use of the

machinery is approved by the commissioner of the Department for Natural

Resources.

(2) Mining equipment being transported or trammed underground, where energized

trolley wires or trolley feeder wires are present, other than ordinary sectional

movements, shall be transported or trammed by qualified personnel under the

supervision of a certified foreman. When the equipment is being transported or

trammed, no person, except those persons directly engaged in moving the

equipment, shall be permitted to be inby the equipment in the ventilating split that is

passing over the equipment. To avoid accidental contact with power lines, face

equipment shall be insulated and assemblies removed, if necessary, so as to provide

clearance.
