(9) Where the only means of egress in a mine is by apparatus worked by steam or electricity, precautions
shall be taken to ensure that the two winding engines do not fail simultaneously, and in particular, in the
case of electric winding engines, the engines shall be capable of being connected to two separate power
supplies. Unless the Chief Inspector by an order in writing otherwise directs, the provisions of this subregulation
shall be deemed to be satisfied if an emergency winding gear is maintained.
(10)(a) Except in the ‘koepe’ system of winding, at the top of every shaft or winze where cages are used,
suitable keps shall be provided and so arranged as to fall into the ‘on’ position when the operating lever is
released.
(b)At every inset where keps or folding platforms are provided, arrangements shall be made to lock the
keps or platforms securely in the ‘off’ position; and when in the ‘off’ ‘ position, such keps or platforms
shall leavel the shaft or winze clear for the passage of the cage. In every such case, a proper automatic
indicator to show the position of the keps or platforms, as the case may be, shall be provided in such a
position as to be easily seen by the banksman.
(11)(a) Unless otherwise permitted by the Chief Inspector by an order in writing and subject to such
conditions as he may specify therein every cage of other means of conveyance in which persons ride in a
vertical or steeply inclined shaft or winze shall be –
(i)
(ii)
(iii)

covered completely at the top;
closed in at the two sides in a manner sufficient to prevent persons or things from projecting
beyond the sides;
provided with a rigid hand-bar fixed in a position where it can be easily reached by all persons in
the cage or other means of conveyance; and
provided with suitable gates or other rigid fences such that the gap between the floor of cage or
other means of conveyance and the lowest part of the gate of fence does not exceed 15 centimetres
and that between any two members of the gate or fence does not exceed 25 centimetres. Gates or
fences shall not open outwards; and they shall be so fitted and maintained that they cannot be
accidentally opened.
Provided that so much of this sub-regulation as requires a covering at the top shall not apply in a
shaft or winze which is less than 30 metres in depth.
(b) The floor of every cage or other means of conveyance shall be strongly constructed and so maintained
to prevent any part of the body of a person riding in the cage or other means of conveyance from projecting
beyond the floor.
(12) Not more than such number of persons as may be authorised by the manager shall be a llowed to ride in
the same cage or same deck of a cage or other means of conveyance at one time; and a notice
specifying the number shall be posted at the top of every shaft or winze and at every inset and landing
:
Provided that where the Regional Inspector is of the opinion that the number so authorised is high, he
may, by an order in writing, required the manager to fix a lower maximum number of persons as may
be specified by him.
(13)(a) Unless permitted by the Chief Inspector by an order in writing and subject to such conditions as he
may specify therein, the total load when the authorised number of persons ride at any one time in any cage
or other means of conveyance shall not exceed 60 per cent of the maximum load when materials are would.
