Prevention of flammable gas and coal dust explosions in collieries

transfer points, in return airways, on equipment and at any other identified high-risk areas (e.g. decommissioned production panels).

8.7. Inertisation of coal dust

Refer to Annexure C: Stone Dust Inertisation Standard, Compliance Sampling and Analysis of Samples

The COP should set out measures that will ensure compliance with requirements relating to effective achievement of coal dust inertisation at least as set out in Annexure C which include:

8.7.1. Inertisation of coal dust by using water;

8.7.2. Inertisation of coal dust by the application of stone dust;

8.7.3. The extent of stone dust application;

8.7.4. Estimating qualitatively the degree of in-situ inertisation achieved; and

8.7.5. Frequency for the application of stone dust.

8.8. Compliance with requirements relating to sampling and analysis of samples

The COP should set out measures to ensure that compliance with requirements relating to sampling and analysis of stone-dust samples is achieved covering at least the content as set out in Annexure C.

8.9. Compliance with requirements relating to the design of barriers to prevents the propagation of coal dust explosions

The COP should set out measures to ensure that compliance with requirements relating to the design of explosion propagation barriers to prevent the spread of coal dust explosions is achieved based on at least the contents of Annexure D.

8.10. Explosions in pit, tank, vessel, container or chamber likely to contain noxious or flammable fumes or gases or an atmosphere deficient in oxygen

The COP should set out measures to prevent the accumulation and ignition of flammable gas and/or explosive mixtures in confined spaces on surface such as beneficiation plants, silo’s, containers and bunkers must be stipulated.
