### sec.223 Monitoring and sampling mine atmosphere An underground mine’s safety and health management system must provide for continuous monitoring of the mine atmosphere, using the mine’s gas monitoring system, at the return airway of each ventilation split. The safety and health management system must also provide for sampling of the mine atmosphere, using the mine’s gas monitoring system, at each of the following places— the return airway from each goaf area and each set of workings; the return of each airway at the upcast shaft; other places stated in the mine’s principal hazard management plan for gas monitoring as places where gas monitoring must be carried out. The safety and health management system must also provide for— continuous monitoring, using the mine’s gas monitoring system, to detect products of combustion in the mine atmosphere at the return side of each conveyor belt; and when the products are detected, the automatic activation of an alarm located on the surface in a position that is generally under observation to warn persons of the products’ presence. The safety and health management system must also provide for a regularly updated plan to be kept at the mine showing the location of— the sampling point for each of the places mentioned in subsections (1) , (1A) and (1B) ; and each of the mine’s ventilation control devices designated under section 351 (1) . A person must not relocate equipment used for sampling without the mine’s ventilation officer’s authorisation. s 223 amd 2020 SL No. 118 s 5 (sec.223-ssec.1) An underground mine’s safety and health management system must provide for continuous monitoring of the mine atmosphere, using the mine’s gas monitoring system, at the return airway of each ventilation split. (sec.223-ssec.1A) The safety and health management system must also provide for sampling of the mine atmosphere, using the mine’s gas monitoring system, at each of the following places— the return airway from each goaf area and each set of workings; the return of each airway at the upcast shaft; other places stated in the mine’s principal hazard management plan for gas monitoring as places where gas monitoring must be carried out. (sec.223-ssec.1B) The safety and health management system must also provide for— continuous monitoring, using the mine’s gas monitoring system, to detect products of combustion in the mine atmosphere at the return side of each conveyor belt; and when the products are detected, the automatic activation of an alarm located on the surface in a position that is generally under observation to warn persons of the products’ presence. (sec.223-ssec.2) The safety and health management system must also provide for a regularly updated plan to be kept at the mine showing the location of— the sampling point for each of the places mentioned in subsections (1) , (1A) and (1B) ; and each of the mine’s ventilation control devices designated under section 351 (1) . (sec.223-ssec.3) A person must not relocate equipment used for sampling without the mine’s ventilation officer’s authorisation. - (a) the return airway from each goaf area and each set of workings; - (b) the return of each airway at the upcast shaft; - (c) other places stated in the mine’s principal hazard management plan for gas monitoring as places where gas monitoring must be carried out. - (a) continuous monitoring, using the mine’s gas monitoring system, to detect products of combustion in the mine atmosphere at the return side of each conveyor belt; and - (b) when the products are detected, the automatic activation of an alarm located on the surface in a position that is generally under observation to warn persons of the products’ presence. - (a) the sampling point for each of the places mentioned in subsections (1) , (1A) and (1B) ; and - (b) each of the mine’s ventilation control devices designated under section 351 (1) .
