  • Risk Scope:
    Hot spots leading to coal fire which may occur in-pit/in-seam or created stockpiles (in-pit and around the processing plants). Excludes ignition of coal dust, explosions in bins (i.e.. confined space), blasting in bins and blasting in hot/reactive ground,

  • Control Objective:
    To ensure the safety of personnel and risk to plant / equipment with respect to the risk of spontaneous combustion of coal both in-pit or on coal stockpiles.

Management of Spontaneous Combustion In-pit and on Coal Stockpiles

The management of spontaneous combustion in-pit and on coal stockpiles is designed, implemented, maintained, and operated in accordance with legislative, Australian Standards and internal BMA / GRM requirements which includes: • 280.01 GRM SOP Stockpile Vehicle and Mobile Equipment Operations

  • Coal that is susceptible to spontaneous combustion is identified and in the case where this needs to be stockpiled, the following is carried out:

  • a) Stockpile designed with an elongated, low profile and long axis parallel to prevailing wind direction.

  • b) Coal temperature monitored based on frequency determined by a JSA.

  • c) Load-out must be from downwind end, with the oldest coal removed first.

  • d) Risk of spontaneous combustion minimised by ensuring old ROM or crush coal is removed (ie.
    fed into wash plant or loaded onto a train) within a three month period of being stockpiled.

  • Select three CMW's (including at least 1 CPP Dozer Operator & 1 OCE in the sample)

  • Do CMW's understand the required management strategies for coal that is susceptible to spontaneous combustion?

  • Has old ROM or crush coal been strategically removed (ie. fed into wash plant or loaded onto a train) within a three month period of being stockpiled?

  • Select 1 known case of susceptible spontaneous combustion in the last 12 months, and verify the following:

  • Was the associated stockpile designed with elongated, low profile and long axis parallel to prevailing wind direction?

  • Was the coal temperature monitored in accordance with frequency recognised in JSA?

  • Was coal load-out from downwind end, with oldest coal removed first?

  • Hot coal in the pit face, ROM or crush stockpiles is managed as follows:

  • a) Hot coal and process separated through the wash plant as soon as practical, following completion of a Job Step Analysis (JSA).

  • b) If the hot coal cannot be fed through the plant immediately, hot coal is separated and spread out to dissipate the heat.

  • Select three CMW's (including at least 1 CPP Dozer Operator & 1 OCE in the sample)

  • Do CMW's understand the required management strategies for hot coal in the pit face, ROM or crush stockpile?<br>

  • Select 1 known case of hot coal in the last 12 months, and verify the following:

  • Was the coal separated through the wash plant as soon as practical, following completion of a Job Step Analysis (JSA)?

  • If the hot coal could not be fed through the plant immediately, was it separated and spread out to dissipate the heat?
