### sec.125 Safety and health management system for highwall mining If highwall mining is carried out at a surface mine, the mine’s safety and health management system must provide for conducting the highwall mining activity in a way that controls the risk of unplanned highwall instability. The system must include standard operating procedures for the following— the entry of persons to, and the evacuation of persons from, an area where highwall mining is carried out; fire prevention, and fire fighting, associated with highwall mining; identifying and marking areas near highwall mining where— explosive atmospheres may occur; or it is safe to use cutting and welding equipment, or smoke cigarettes; continuously monitoring oxygen and methane in the atmosphere at the cutting face in the highwall mining excavation during cutting if an explosive atmosphere that may cause a risk is present, or suspected to be present, in the excavation; working safely in areas where there is a potential for flooding from any source; enabling a person to communicate with a person on the surface when work is being carried out in the underground excavation. The procedure mentioned in subsection (2) (c) must provide for— monitoring the areas for the potential for the formation of an ERZ; and deciding whether— equipment used in the areas needs explosion protection; and aluminium alloys used in the areas need protection to minimise the risk of explosion. The procedure mentioned in subsection (2) (e) must provide for ongoing risk assessment of the potential for inrush, outrush and flooding. (sec.125-ssec.1) If highwall mining is carried out at a surface mine, the mine’s safety and health management system must provide for conducting the highwall mining activity in a way that controls the risk of unplanned highwall instability. (sec.125-ssec.2) The system must include standard operating procedures for the following— the entry of persons to, and the evacuation of persons from, an area where highwall mining is carried out; fire prevention, and fire fighting, associated with highwall mining; identifying and marking areas near highwall mining where— explosive atmospheres may occur; or it is safe to use cutting and welding equipment, or smoke cigarettes; continuously monitoring oxygen and methane in the atmosphere at the cutting face in the highwall mining excavation during cutting if an explosive atmosphere that may cause a risk is present, or suspected to be present, in the excavation; working safely in areas where there is a potential for flooding from any source; enabling a person to communicate with a person on the surface when work is being carried out in the underground excavation. (sec.125-ssec.3) The procedure mentioned in subsection (2) (c) must provide for— monitoring the areas for the potential for the formation of an ERZ; and deciding whether— equipment used in the areas needs explosion protection; and aluminium alloys used in the areas need protection to minimise the risk of explosion. (sec.125-ssec.4) The procedure mentioned in subsection (2) (e) must provide for ongoing risk assessment of the potential for inrush, outrush and flooding. - (a) the entry of persons to, and the evacuation of persons from, an area where highwall mining is carried out; - (b) fire prevention, and fire fighting, associated with highwall mining; - (c) identifying and marking areas near highwall mining where— (i) explosive atmospheres may occur; or (ii) it is safe to use cutting and welding equipment, or smoke cigarettes; - (i) explosive atmospheres may occur; or - (ii) it is safe to use cutting and welding equipment, or smoke cigarettes; - (d) continuously monitoring oxygen and methane in the atmosphere at the cutting face in the highwall mining excavation during cutting if an explosive atmosphere that may cause a risk is present, or suspected to be present, in the excavation; - (e) working safely in areas where there is a potential for flooding from any source; - (f) enabling a person to communicate with a person on the surface when work is being carried out in the underground excavation. - (i) explosive atmospheres may occur; or - (ii) it is safe to use cutting and welding equipment, or smoke cigarettes; - (a) monitoring the areas for the potential for the formation of an ERZ; and - (b) deciding whether— (i) equipment used in the areas needs explosion protection; and (ii) aluminium alloys used in the areas need protection to minimise the risk of explosion. - (i) equipment used in the areas needs explosion protection; and - (ii) aluminium alloys used in the areas need protection to minimise the risk of explosion. - (i) equipment used in the areas needs explosion protection; and - (ii) aluminium alloys used in the areas need protection to minimise the risk of explosion.
