The Director shall not promulgate any regulations relating to underground mineral mines which are inconsistent with requirements established by the Act, or which, when an operator takes action to comply with the provisions of such regulation, would place the operator in violation of the federal mine safety law.
1994, c. 28; 1996, c. 774; 1998, c. 695.§ 45.1-161.295. Standards for regulations.
In promulgating rules and regulations pursuant to § 45.1-161.294, the Director shall consider:
1. Standards utilized and generally recognized by the underground mineral mining industry;
2. Standards established by recognized professional mineral mining organizations and groups;
3. The federal mine safety law;
4. Research, demonstrations, experiments, and such other information that is available regarding the maintenance of a reasonable degree of safety protection, including the latest available scientific data in the field, the technical and economic feasibility of the standards, and the experience gained under this Act and other mine safety laws; and
5. Such other criteria as shall be necessary for the protection of safety and health of miners and other persons or property likely to be affected by underground mineral mines or related operations.
1994, c. 28.§ 45.1-161.296. Mining in proximity to gas and oil wells.
A. The Director shall promulgate regulations requiring licensed operators to notify, and in appropriate circumstances obtain the consent of, the Director prior to removing minerals in the proximity of any gas or oil well already drilled or in the process of being drilled.
B. Any licensed operator who plans to remove any mineral, drive any passage or entry or extend any workings in any mine closer than 500 feet to any gas or oil well already drilled or in the process of being drilled shall file with the Director a notice that mining is taking place or will take place, together with a copy of parts of the maps and plans required under § 45.1-161.292:37, which show the mine workings and projected mine workings which are within 500 feet of the well. The licensed operator shall simultaneously mail copies of such notice, maps and plans by certified mail, return receipt requested, to the well operator and the Gas and Oil Inspector. Each notice shall contain a certification made by the sender that he has complied with these requirements.
C. Subsequent to the filing of the notice, the licensed operator may proceed with mining operations in accordance with the maps and plans; however, without the prior approval of the Director, he shall not remove any material, drive any entry, or extend any workings in any mine closer than 200 feet to any gas or oil well already drilled or in the process of being drilled. Each licensed operator who files such a petition shall mail copies of the petition, maps and plans by certified mail, return receipt requested, to the well operator and the Gas and Oil Inspector no later than the day of filing. The Gas and Oil Inspector and the well operator shall have standing to object to any petition filed under this section. Such objections shall be filed within ten days following the date such petition is filed.

B. Until the final regulations promulgated by the Director pursuant to subsection A become effective, the following standards shall apply to the transportation of mining equipment underground:
1. Prior to moving or transporting any unit of off-track mining equipment in areas of the active workings where energized trolley wires or trolley feeder wires are present: (i) the unit of equipment shall be examined by a certified person to ensure that accumulations of oil, grease, and other combustible materials have been removed from such unit of equipment; and (ii) a qualified person shall examine the trolley wires, trolley feeder wires, and the associated automatic circuit interrupting devices to ensure that proper short circuit protection exists.
2. A record shall be kept of the examinations and shall be made available, upon request, to the Director or his authorized representative.
3. Off-track mining equipment shall be moved or transported in areas of the active workings where energized trolley wires or trolley feeder wires are present only under the direct supervision of a certified person who shall be physically present at all times during moving or transporting such equipment.
4. The frames of off-track mining equipment being moved or transported, in accordance with this subsection, shall be covered on the top and on the trolley wire side with fire-resistant material, where appropriate as determined by the Director.
5. Electrical contact shall be maintained between the mine track and the frames of off-track mining equipment being moved in-track and trolley entries, except that rubber-tired equipment need not be grounded to a transporting vehicle if no metal part of such rubber-tired equipment can come into contact with the transporting vehicle.
6. To avoid accidental contact with power lines, the equipment being transported or trammed shall be insulated or assemblage removed, if necessary, if the clearance to the power lines is six inches or less.
7. Sufficient prior notice shall be given the Department so that a mine inspector may travel the route of the move before the actual move is made, if he deems it necessary.
8. A minimum vertical clearance of twelve inches shall be maintained between the farthest projection of the unit of equipment which is being moved and the energized trolley wires or trolley feeder wires at all times during the movement or transportation of such equipment. If the height of the seam of minerals does not permit twelve inches of vertical clearance to be so maintained, the following additional precautions shall be taken:
a. Electric power shall be supplied to the trolley wires or trolley feeder wires only from outby the unit of equipment being moved or transported. Where direct current electric power is used and such electric power can be supplied only from inby the equipment being moved or transported, power may be supplied from inby such equipment if a miner with the means to cut off the power, and in direct communication with persons actually engaged in the moving or transporting operation, is stationed outby the equipment being moved;
b. The settings of automatic circuit interrupting devices used to provide short circuit protection for the trolley circuit shall be reduced to not more than one-half of the maximum current that could flow if the equipment being moved or transported were to come into contact with the trolley wire or trolley feeder wire;
c. At all times the unit of equipment is being moved or transported, a miner shall be stationed at the first automatic circuit breaker outby the equipment being moved. Such miner shall be in direct communication with persons actually engaged in the moving or transporting operation, and capable of communicating with the authorized person on the surface required to be on duty;
d. Where trolley phones are utilized to satisfy the requirements of paragraph c of this subdivision, telephones or other equivalent two-way communication devices that can readily be connected with the mine communication system shall be carried by the miner stationed at the first automatic circuit breaker outby the equipment being moved and by a miner actually engaged in the moving or transporting operation; and
e. No person shall be permitted to be inby the unit of equipment being moved or transported, in the ventilating current of air that is passing over such equipment, except those persons directly engaged in moving such equipment.
The provisions of subdivisions 1 through 8 shall not apply to units of mining equipment that are transported in mine cars, provided that no part of the equipment extends above or over the sides of the mine car.
