### sec.300 General An underground mine’s safety and health management system must provide for the following— minimising the risk of coal dust explosion; suppressing coal dust explosion and limiting its propagation to other parts of the mine, including by installing and maintaining explosion barriers as required under section 303A . The system must provide for the following— limiting coal dust generation, including its generation by mining machines, coal crushers and coal conveyors and at conveyor transfer points; suppressing, collecting and removing airborne coal dust; limiting coal dust accumulation on roadway and other surfaces on mine roadways; removing excessive coal dust accumulations in roadway and other surfaces in mine roadways; deciding the stonedust or other explosion inhibitor application rate necessary to minimise the risk of a coal dust explosion. The mine must have a standard operating procedure for the following— regularly inspecting, sampling and analysing roadway dust layers, including laboratory analysis for incombustible material content; applying stonedust or another explosion inhibitor for suppressing coal dust explosion. The procedure must provide for the dust sampling and analysis mentioned in subsection (3) (a) to be carried out at least at the following intervals— for a strip or spot sample of dust mentioned in section 301 (1) (a) or (b) —weekly; for a strip sample of dust mentioned in section 301 (1) (a) , (b) , (c) or (d) —monthly; for a strip sample of dust mentioned in section 301 (1) (e) —every third month. The procedure must also provide for the analysis of each sample mentioned in subsection (4) (b) or (c) to be carried out in a laboratory. s 300 amd 2020 SL No. 221 s 4 (sec.300-ssec.1) An underground mine’s safety and health management system must provide for the following— minimising the risk of coal dust explosion; suppressing coal dust explosion and limiting its propagation to other parts of the mine, including by installing and maintaining explosion barriers as required under section 303A . (sec.300-ssec.2) The system must provide for the following— limiting coal dust generation, including its generation by mining machines, coal crushers and coal conveyors and at conveyor transfer points; suppressing, collecting and removing airborne coal dust; limiting coal dust accumulation on roadway and other surfaces on mine roadways; removing excessive coal dust accumulations in roadway and other surfaces in mine roadways; deciding the stonedust or other explosion inhibitor application rate necessary to minimise the risk of a coal dust explosion. (sec.300-ssec.3) The mine must have a standard operating procedure for the following— regularly inspecting, sampling and analysing roadway dust layers, including laboratory analysis for incombustible material content; applying stonedust or another explosion inhibitor for suppressing coal dust explosion. (sec.300-ssec.4) The procedure must provide for the dust sampling and analysis mentioned in subsection (3) (a) to be carried out at least at the following intervals— for a strip or spot sample of dust mentioned in section 301 (1) (a) or (b) —weekly; for a strip sample of dust mentioned in section 301 (1) (a) , (b) , (c) or (d) —monthly; for a strip sample of dust mentioned in section 301 (1) (e) —every third month. (sec.300-ssec.5) The procedure must also provide for the analysis of each sample mentioned in subsection (4) (b) or (c) to be carried out in a laboratory. - (a) minimising the risk of coal dust explosion; - (b) suppressing coal dust explosion and limiting its propagation to other parts of the mine, including by installing and maintaining explosion barriers as required under section 303A . - (a) limiting coal dust generation, including its generation by mining machines, coal crushers and coal conveyors and at conveyor transfer points; - (b) suppressing, collecting and removing airborne coal dust; - (c) limiting coal dust accumulation on roadway and other surfaces on mine roadways; - (d) removing excessive coal dust accumulations in roadway and other surfaces in mine roadways; - (e) deciding the stonedust or other explosion inhibitor application rate necessary to minimise the risk of a coal dust explosion. - (a) regularly inspecting, sampling and analysing roadway dust layers, including laboratory analysis for incombustible material content; - (b) applying stonedust or another explosion inhibitor for suppressing coal dust explosion. - (a) for a strip or spot sample of dust mentioned in section 301 (1) (a) or (b) —weekly; - (b) for a strip sample of dust mentioned in section 301 (1) (a) , (b) , (c) or (d) —monthly; - (c) for a strip sample of dust mentioned in section 301 (1) (e) —every third month.
