(b) Except as provided in subsection (i) of this section, if, upon any inspection of a coal mine, an authorized representative of the Secretary finds that there has been a violation of any mandatory health or safety standard but the violation has not created an imminent danger, he shall issue a notice to the operator or his agent fixing a reasonable time for the abatement of the violation. If, upon the expiration of the period of time as originally fixed or subsequently extended, an authorized representative of the Secretary finds that the violation has not been totally abated, and if he also finds that the period of time should not be further extended, he shall find the extent of the area affected by the violation and shall promptly issue an order requiring the operator of such mine or his agent to cause immediately all persons, except those referred to in subsection (d) of this section, to be withdrawn from, and to be prohibited from entering, such area until an authorized representative of the Secretary determines that the violation lias been abated. (c)(1) If, upon any inspection of a coal mine, an authorized representative of the Secretary finds that there has been a violation of any mandatory health or safety standard, and if he also finds that, while the conditions created by such violation do not cause imminent danger, such violation is of such nature as could significantly and substantially contribute to the cause and effect of a mine safety or health hazard, and if he finds such violation to be caused by an unwarrantable failure of such operator to comply with such mandatory health or safety standards, he shall include such finding in any notice given to the operator under this Act. If, during the same inspection or any subsequent inspection of such mine within ninety days after the issuance of such notice, an authorized representative of the Secretary finds another violation of any mandatory health or safety standard and finds such violation to be also caused by an unwarrantable failure of such operator to so comply, he shall forthwith issue an order requiring the operator to cause all persons in the area affected by such violation, except those persons referred to in subsection (d) of this section, to be withdrawn from, and to be prohibited from entering, such area until an authorized representative of the Secretary determines that such violation has been abated. (2) If a withdrawal order with respect to any area in a mine has been issued pursuant to paragraph (1) of this subsection, a withdrawal order shall promptly be issued by an authorized representative of the Secretary who finds upon any subsequent inspection the existence in such mine of violations similar to those that resulted in the issuance of the withdrawal order under paragraph (1) of this subsection until such time as an inspection of such mine discloses no similar violations. Following an inspection of such mine which discloses no similar violations, the provisions of paragraph (1) of this subsection shall again be applicable to that mine. (d) The following persons shall not be required to be withdrawn from, or prohibited from entering, any area of the coal mine subject to an order issued under this section: (1) any person whose presence in such area is necessary, in the judgment of the operator or an authorized representative of the Secretary, to eliminate the condition described in the order;
