### sec.213 Where explosives for shotfiring may be used
The person directly supervising and controlling a shotfiring activity at an underground mine must ensure the place where the explosives are prepared, charged or fired has the following features—
a general body concentration of methane of less than 0.5%;
a ventilation current capable of quickly diluting and removing any atmospheric contaminants released by the shot;
its exposed surfaces within a radius of 20m from the location of the shot are—
thoroughly saturated with water; or
treated with stonedust so the deposited dust mixture comprises an incombustible coal dust concentration of at least 85%.
Subsection (1) (c) does not apply to an excavation—
in stone and in which—
the full length of the shothole is in stone; and
no coal is exposed, or coal dust deposited, within a 20m radius of the shot location; or
more than 5m from the nearest known coal seam.
(sec.213-ssec.1) The person directly supervising and controlling a shotfiring activity at an underground mine must ensure the place where the explosives are prepared, charged or fired has the following features— a general body concentration of methane of less than 0.5%; a ventilation current capable of quickly diluting and removing any atmospheric contaminants released by the shot; its exposed surfaces within a radius of 20m from the location of the shot are— thoroughly saturated with water; or treated with stonedust so the deposited dust mixture comprises an incombustible coal dust concentration of at least 85%.
(sec.213-ssec.2) Subsection (1) (c) does not apply to an excavation— in stone and in which— the full length of the shothole is in stone; and no coal is exposed, or coal dust deposited, within a 20m radius of the shot location; or more than 5m from the nearest known coal seam.
