Air Measurements. [Section 29, Sub-section 2.]

(67.) The points at which the quantity of air shall be
measured in pursuance of Sub-section 2 of Section 29 of
the Act shall be as follows :—

(a)	In the main intake airways of every seam as
near as practicable to the downcast shaft;

(&) In every split as near as practicable to the point
at which the split commences, and

(c) In each ventilating district at or as near as
practicable to a point 100 yards back from the
first working place at the working face which
the air enters.

Use of Electric Lamps. [Section 32.]

(68.) Where safety lamps are required to be used,
electric lamps, if enclosed in airtight fittings and having
the lamp globes hermetically sealed, may, subject to the
provisions of the Act and any Regulations made there-
under as to the use of electricity in mines, be used
within the following limits:—

(a) On main intake airways and haulage roads
ventilated by intake air up to within 300 yards
of the first working place at the working face
which the air enters.

(&) On main return airways within 300 yards of the
bottom of the upcast shaft if that shaft is
regularly used for the purpose of winding
persons or minerals but not within 300 yards
of the last working place at the working face
which the air leaves.

Character of Winding Apparatus, &c. [Section 40 (1).]

(69.) In every mine which is not a small mine the
apparatus for raising and lowering persons to or from
the surface, hereinafter called the winding apparatus,
in any shaft which is more than 150 ft. in depth, shall
be worked by mechanical power.

(70.) Winding apparatus worked by mechanical
power :•»—

(a)	shall be so designed, constructed and maintained

that, with the power provided, the raising and
lowering of persons can be carried out with
ease, regularity and safety ;

(b)	if installed after the date on which these

regulations come into force, shall have the
drum shafts, if 10 in. or more in diameter,
bored longitudinally at the centre ;

(c)	shall be firmly connected to a rigid foundation

so as to prevent any material movement of
the apparatus as a whole.

(71.) Where winding apparatus is worked by other
than mechanical power it shall be efficiently constructed
and maintained, and provided with a locking device or
brake sufficient in itself to hold the load in the shaft at
any point.

(72.) All cage chains shall be annealed once at least in
every six months, and detaching hooks shall be cleaned
and refitted once in every three months.

Capping of Winding and Hauling Ropes. [Sections 40 (5)
and 46.]

The following regulations shall not apply to ropes
used for hauling mineral on self-acting inclines from
the face.

(73.) No mode or type of capping shall be used which
fails to withstand a strain of at least 75 per cent, of the
breaking strain of the rope.

(74.) A competent person appointed in writing by the
Manager, shall, whenever a winding rope is capped or
recapped, superintend the work, and see that it is
properly carried out.

(75.) In no case shall the capel be attached to the
rope by the use of rivets passing through the rope.

(76.) In those forms of capping in which the wires at
the end of the rope are bent back on the rope itself to
form a cone, wedges of a soft metal shall be placed'

between the rope and that portion which is bent back.
This regulation shall not apply to hauling ropes if
mineral only is hauled or if the gradient is less than
45 degs.

(77.) If white metal is used in the capping of ropes,
the composition of the white metal shall be such that its
melting point is under 500 degs. Fahr.

(78.) Where white metal is used in the capping of
ropes the untwisted wires shall be thoroughly cleaned
and dusted with resin, and, before the white metal is
poured into the socket, the latter shall be heated or
warmed.

Exemptions from the Provision requiring two Main
Intake Airways. [Section 42 (1).]

(79.) The provision in Section 42, Sub-section (1), of the
Act requiring two main intake airways shall not apply :

(a.) To any seam the coal of which is so liable to
spontaneous combustion that the provision of
a second main intake airway in such seam
would greatly increase the risk of fire.

(6.) To any seam where, owing to the character of
the strata or the nature of the pressure, the
cost of maintaining two main intake airways
in that seam might be so great as to prevent
the mine being worked at a profit.

(c.) To any part of a seam where the mineral field
leased or owned is not of sufficient width to
allow the distances required by the regulations
of the mine to be maintained between the
roads in such part.

(d.) To mines of stratified ironstone in the Cleve-
land District, or to mines in any other district
as respects which the Secretary of State is
satisfied that similar conditions prevail.

(e.) To any mine in which the number of persons
employed below ground does not at any one
time exceed one hundred.

(/.) To any seam which is naturally wet throughout.

If any question arises as to whether any of the
foregoing exemptions applies to a mine or seam, that
question shall be determined in the manner provided by
the Act for settling disputes.

(80.) The distance from the downcast shaft within
which the two main intake airways shall not be required
to be provided shall be the distance between the shaft
and the edge of the shaft pillars.

Construction of Stoppings. [Section 42 (3).]

(81).—(a) All stoppings between main intake and
main return airways shall be constructed of tight stone
or dirt packing at least three yards thick, and shall have
one end of the packing (which end, if either road is used
as a haulage or travelling road, shall be the end next
to that road) faced with a wall of masonry, brickwork or
concrete not less than 14 inches thick, the side, top and
bottom of which shall be let where practicable into firm
ground, and the face covered with a coating of mortar,
so as to prevent leakage of air.

(6) The space between the face of the stopping and
the roadway shall be kept clear.

(c) This Regulation shall apply only to mines in
which coal is worked.

Signalling (except in sinking pits). [Section 53. J

there are entrances into the workings from the shaft
at different levels, prescribe the signals to be used to*
indicate the level to which the cage is to be sent, and in
respect of movements of the cage between one level and
another level, and shall fix any other signals that may
be required.
