51. (1) In sinking shafts the bucket, cage or skip shall not be filled above the level of the brim.
(2) Before the bucket, cage or skip leaves the top or bottom of the shaft it shall be steadied under the supervision of the gang foreman in charge.
(3) In no event shall any bucket, cage or skip be directly lowered to the bottom of a shaft when men are working there, but shall be stopped at least 4.5 metres above the bottom until the signal to lower it further has been given by the signalman thereat:
Provided that this paragraph shall not apply to shafts in which the miners are not more than 15 metres from the winch or windlass controller.
52. Ladder ways shall be provided in all shafts in the course of sinking to within such distance of the bottom as will secure them from damage in blasting, and from the ends of such ladder ways chain ladders shall be extended to the bottom of the shaft:
Provided that chains may be substituted for chain ladders in an inclined shaft.
53. (1) When a shaft has no separate ladder way under which those engaged in sinking may find shelter, during the winding of rock materials or water, sufficient protection shall be provided by a suitable covering.
(2) When a working shaft is being sunk deeper while ordinary winding is going on the men employed at the bottom of such shaft shall be securely protected by overhead cover.
54. All hoisting appliances in use at shafts and winzes shall be provided with a stopper, pawl or some other reliable holder, and care must be taken that the hooking on and off of buckets or other receptacles is done without danger to the workmen.
55. (1) Every winding shaft which exceeds 15 metres in depth shall be provided with efficient means of interchanging distinct and definitive signals between---
(a) the winding engine,
(b) the top of the shaft,
(c) the lowest point from which winding is carried on, and (d) the various intermediate stations for the time being in use, but this paragraph shall not apply to signalling apparatus used during sinking operations.
(2) A mines officer may in writing exempt any shaft from the whole or part of the requirements of paragraph (1) and any exemption may be varied or revoked by a mines officer at 7 day's notice. An appeal shall lie from any such variation or revocation to the Superintendent of Mines.
