MINES ACT (NORTHERN IRELAND) 1969 - SECT 58

Provisions as to means of ventilation.

58.(1) Unless, in all parts of a mine that are required by section 55 to be
ventilated, ventilation adequate for the purposes specified in subsection (1)
of that section is provided wholly by natural means, there shall be provided
and maintained on the surface of the mine mechanically operated apparatus
capable of producing in all those parts of the mine an amount of ventilation
sufficient (apart from any ventilation produced by any mechanically operated
apparatus below ground) to enable all the persons who are below ground in the
mine at any one time to leave it safely; and any apparatus provided in
pursuance of this subsection shall, if it is not normally used to produce
ventilation, be used once at least in each week and be kept constantly
available for use.

(2) Where (whether in pursuance of subsection (1) or not) there is provided on
the surface of a mine of coal mechanically operated apparatus for producing
ventilation below ground in the mine, then, unless that apparatus is so
designed or adapted, and is so installed, as to permit of its operation both
by way of forcing air into, and by way of exhausting air from, the mine, there
shall be provided in association with that apparatus, maintained and kept
constantly available for use, adequate means for reversing the direction of
flow of the ventilation produced by that apparatus.

(3) Subject to subsection (4), regulations may

(a)exempt any prescribed class of mines from the provisions of subsection (1);

(b)exempt any prescribed class of mines of coal from the provisions of
subsection (2);

(4) No exemption shall be granted by regulations made by virtue of subsection
(3) unless the Ministry is satisfied that no persons employed in mines of the
class to which the regulations apply will be exposed to undue risk in
consequence of the granting of the exemption; and no exemption shall be
granted under that subsection by the Ministry in the case of a particular mine
unless an inspector reports to the Ministry that he is satisfied that no
persons employed in that mine will be exposed to undue risk in consequence of
the granting of the exemption.

(5) It shall not be lawful to use a fire for ventilation in a mine or, except
with the consent of the Ministry, given by notice served on the manager of the
mine, to release in a mine compressed air for the purpose thereby of diluting
or removing inflammable or noxious gas.
