[No. 79

without the written permission of the manager or of the
official under whose directions he works, allow any one to
work the engine. He shall in no circumstances permit any
one, except with the authority in writing of the manager, to
work the engine while persons are being raised or lowered in
the shaft.

Persons in Charge of Ventilating-machines.

The following regulations shall not apply to any auxiliary
fan placed underground which does not contribute to the
general ventilation of the mine or of any ventilating district
of the mine:—

100. The owner or manager shall cause to be provided in
     connection with every ventilating-fan driven by mechanical
     power a water-gauge and either an automatic indicator
     registering the number of revolutions of the fan or an
     automatic indicator registering the water-gauge.

101. The person in charge of any ventilating machinery
     driven by mechanical power shall keep the machinery running
     at the speed ordered by the manager or underviewer, and
     shall examine the machinery and observe the indicators at
     intervals which in the case of mines in which safety-lamps
     are required by the said Act or by the additional rules of the
     mine to be used shall be of not more than half an hour or
     such longer time as may be approved by the Inspector, and
     in the case of other mines shall be of not more than two hours.

102. The person in charge of any ventilating machinery
     as aforesaid shall immediately report to the official under
     whose direction he works any damage to, or defect or derange-
     ment in, the machinery.

103. He shall from time to time observe the ventilating
     pressure as indicated by the water-gauge, and where an
     automatic indicator registering the water-gauge is not in use,
     he shall at the end of each period of two hours enter in a book
     to be provided by the manager the number of revolutions of
     the fan and the pressure shown by the water-gauge at the
     end of that period.

104. In the event of a stoppage of the machinery or of any
     unusual variation of the water-gauge he shall at once inform
     the official under whose direction he works.

105. He shall maintain the water in each boiler as nearly
     as practicable at the proper working-level, but if it becomes
     too low he shall at once lower the dampers and damp down
     the fire, and if necessary draw the same, and report the
     circumstance to the official under whose direction he works.
     He shall also see that the pressure of steam fixed by the
     manager is on no account exceeded.

USE OF ELECTRIC LAMPS OTHER THAN LOCKED SAFETY-
LAMPS.

106. In any mine or part of a mine in which 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
     thereunder 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.

(b.) 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.

CAPPING OF WINDING AND HAULING ROPES.

107. No mode or type of capping shall be used which
     fails to withstand a strain—

(a.) In the case of a winding-rope, of at least seven times
the weight of the maximum load carried at any
time by the capel;

(b.) In the case of a hauling-rope, of at least 60 per cent.
of the breaking-strain of the rope.

108. A competent person appointed by the manager shall,
     whenever a winding-rope is capped or recapped, superintend
     the work, and see that it is properly carried out.

109. In no case shall the capel of a round winding-rope
     be attached to the rope by the use of rivets passing through
     the rope.

110. 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, or wedges formed by the lapping of
     soft wire, shall be placed between the rope and that portion
     which is bent back. This regulation shall not apply to
     hauling-ropes if materials only are hauled or if the gradient
     is less than 45°.

111. 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 750 degrees Fahrenheit.

112. Where white metal is used in the capping of ropes
     the untwisted ropes shall be thoroughly cleaned, and before
     the white metal is poured into the socket the latter shall be
     heated or warmed.

113. Where men are raised or lowered in shafts, or carried
     along inclined planes, no spliced rope shall be used.

SIGNALLING (EXCEPT IN SINKING PITS).

Winding.

114. The manager shall, in the case of a mine where 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.

115. A notice shall be posted in the engine-house, and at
     the pit-head, and at each entrance into the workings from the
     shaft, containing the signals fixed by the manager in pur-
     suance of the preceding regulation.

116. In connection with every winding-engine there shall
     be provided an appliance which shall automatically indicate
     in a visible manner to the winding-engineman (in addition
     to the ordinary signal) the nature of the signal until the
     signal is complied with.

117. The foregoing Regulations 114 to 116 shall not come
     into operation until the 1st January, 1916.

Hauling.

118. The following signals shall be used in all mines in
     connection with underground haulage worked by gravity
     or mechanical power:—

(a.) Direct or main-rope haulage—
To stop . . . . . 1
To lower . . . . . 2
To wind up . . . . . 3

(b.) Haulage (other than endless-rope or chain
haulage) on self-acting inclines—
To stop . . . . . 1
To lower . . . . . 2
When persons are about to travel up or
down the incline . . . . . 4
This signal shall be acknowledged by
signalling . . . . . 4

(c.) Main- and tail-rope haulage—
To stop . . . . . 1
To haul inbye . . . . . 2
To haul outbye . . . . . 3
To slack out tail-rope . . . . . 4
To tighten tail-rope . . . . . 5
To slack out main rope . . . . . 6
To tighten main rope . . . . . 7

(d.) Endless-rope haulage—
To commence hauling . . . . . 2
To stop hauling . . . . . 1

119. When persons are about to be conveyed inbye or
     outbye, each of the signals required by the foregoing regula-
     tions to be given when a set or train of tubs is about to be
     hauled inbye or outbye, as the case may be, shall be pre-
     ceded by a cautionary signal of 8.

120. The manager shall, in the case of a mine where there
     are several districts, prescribe the additional signals that
     may be required.

121. A notice shall be posted in the hauling-engine house,
     and at each signalling-station, containing the system of
     haulage signals in use at such engine-house or signalling-
     station.

122. The foregoing Regulations 118 to 121 shall not come
     into operation until the 1st January, 1916.

TELEPHONES.

123. In any mine in which the total number of persons
     employed underground exceeds thirty, and the length of the
     main haulage-road exceeds 1,000 yards, efficient means of
     telephonic communication shall be provided and maintained
     between the end of the main haulage and the surface.

BAROMETER AND THERMOMETER.

124. Every person on whom responsible duties are imposed
     with respect to the ventilation underground, and who is
     required to make a daily report in a book to be kept at the
     mine for the purpose, shall, immediately before going into
     the mine and also after coming out of the mine, read the
     barometer and thermometer required to be placed near the
     entrance to the mine.

EXPLOSIVES.

Part I.—General Provisions.

125. (1.) Nothing in these regulations shall relieve the
     owner or manager of a mine from complying with the provi-
     sions of the Explosives and Dangerous Goods Act, 1908,
     regarding the storage of explosives.
