§ (1) In any part of a mine where any work is being carried out which necessitates the removal of roof supports, temporary supports shall in all cases be set so as to secure the safety of the persons employed.
§ (2) Props shall not be withdrawn from the waste or goaf or under a heavy roof otherwise than by means of a safety contrivance.
§ Amendments made: In Sub-section (2), leave out the words "under a heavy roof," and insert instead thereof the words "from under a roof which appears to a fireman, examiner or deputy to be insecure."
In Sub-section (2), at end, add the words,
and it shall be the duty of the firemen, examiners, and deputies to examine all roofs from under which props are about to be withdrawn with a view
to determining whether the props ought to be withdrawn by means of a safety contrivance."—[Mr. Hunter.]
