### sec.303A Explosion barriers
The underground mine manager for an underground mine must ensure—
explosion barriers are installed and maintained in the part of each of the following roadways within an ERZ1 in a part of the mine where coal is being extracted—
a return roadway;
a single entry drive;
a roadway in which a coal conveyor is installed; or
explosion barriers that are active barriers, devices or systems are installed and maintained on plant within an ERZ1 in a part of the mine where coal is being extracted in a way that would prevent the propagation of a coal dust explosion to a place mentioned in paragraph (a) .
The underground mine manager must also ensure explosion barriers are installed and maintained in a place in the mine, other than a place at which an explosion barrier is installed and maintained in compliance with subsection (1) , identified by a risk assessment for the mine.

In this section—
explosion barrier means—
a barrier, device or system constructed, installed and maintained in compliance with a recognised standard for barriers, devices or systems known as explosion barriers; or
another barrier, device or system that achieves a level of risk that is equal to or better than the acceptable level of risk achieved by a barrier, device or system mentioned in paragraph (a) .
