Part 36 Mining

Section 727 Ventilation monitoring

(1) An employer must appoint a competent worker who must measure the barometric pressure outside the mine and the velocity and quantity of air in all airways and old workings of the mine that are accessible to workers.

(2) An employer must ensure that measurements under subsection (1) are, at a minimum, taken

(a) at the main airway as near as reasonably practicable to the point at which the air enters or leaves the mine,

(b) within each split or part of the mine

(i) as near as reasonably practicable to the points at which air enters and leaves the split or part of the mine, and

(ii) in longwall workings, within 10 metres of the working face in the intake and return airways,

(c) in other mining methods, as near as reasonably practicable to the last open cross cut, and

(d) as near as reasonably practicable to the working face of each active heading.

(e) at seals along intake air courses where intake air passes by a seal to ventilate active working sections.

(3) The appointed worker must notify the mine manager of any abnormalities in the barometric pressure or the velocity and quantity of air.

(4) An employer must ensure that the measurements under subsection (1) are taken at least once a week.

(5) If the quality or quantity of air passing a place where the measurements are taken may be substantially affected because the ventilation system of a mine is altered, an employer must ensure that the appointed worker repeats the measurements as soon as the effect of the alteration would be apparent.

(6) An underground coal mine manager must ensure that before the commencement of each work shift, the appointed worker takes temperature and barometric pressure readings outside the mine.

(7) An appointed worker must

(a) record the results of the measurements taken under this section in the log book provided by the employer for that purpose,

(b) sign each entry, and

(c) post a copy of the results at the portal.
