Mines and Quarries Act 1954

108 Provisions for securing safe methods of working

(1) It shall be the duty of every manager of a quarry to secure that any quarrying operations carried on in a part of the quarry to which his jurisdiction extends are so carried on as to avoid danger from falls (whether within or outside that part and whether of the minerals worked or any other substance).

(2) Without prejudice to the generality of the foregoing subsection, every manager of a quarry shall secure that, in no part of the quarry to which his jurisdiction extends, shall the face or sides of the quarry or any gallery thereon be so worked as to cause any overhanging:

Provided that—

(a) if the Minister is satisfied with respect to any prescribed class of quarries that, having regard to the system of working quarries of that class and the natural condition of the minerals thereof, fulfilment of the requirement imposed, by the foregoing provisions of this subsection is unnecessary to secure the safety of persons employed thereat, regulations may provide that quarries of that class or such parts thereof as may be prescribed shall be exempted from that requirement; and

(b) if an inspector is satisfied with respect to a particular quarry that, having regard to the system of working the quarry and the natural condition of the minerals thereof, fulfilment of that requirement is unnecessary to secure the safety of persons employed thereat, he may, by notice served on the owner of the quarry, exempt the quarry or such part thereof as may be specified in the notice from that requirement.
