(1) The bearings and the lengths of the traverse lines shall be shown on the drawings by means of lines and figures and all traverses shall be reduced.
(2) The true bearings shall be carried from the surface of a mine into the underground workings by accurate method.
(3) Where practicable, the surveys of different levels of a mine shall be connected by direct bearings and measurements through winzes or by traverses through stopes.
(4) Where a closed traverse cannot be obtained otherwise, every traverse which consists of more than one line shall be checked by returning over the same ground with a different set of survey stations.
4.	Instruments for taking bearings.
(1) Where practicable, the instrument used in taking bearings shall be a theodolite and bearings shall be carried into the mine without the use of the magnetic needle.
(2) Where the use of a theodolite is rendered impracticable by the conditions existing in any mine or part of a mine a circumferentor or dial or other form of compass may be used.
(3) Where a circumferentor or dial or other form of compass is used in taking bearings, both back and fore sight shall be taken along each line of the traverses, and corrections shall be made for local magnetic attractions.
(4) Where an instrument referred to in Subsection (3) is used, a checking traverse shall be made unless a complete check of the accuracy of the work can be otherwise shown.
(5) The description of the instrument used in taking the bearings shall be noted on the plan or section.
5.	Measuring instruments.
(1) Subject to Subsection (2), the measurements of–
(a)	the depths of shafts; and
