A coal dust explosion is one of the principal hazards in an underground coal mine. These mines must develop, establish and maintain an adequate and effective safety and health management system (SHMS) to ensure risk from such hazards is at an acceptable level. One of the primary controls against this hazard is the application of stone dust throughout mine roadways to reduce the potential for ...
roadway dust is determined by the settling characteristics of the stone dust and coal dust, the delivery rate of stone dust and the burden of coal dust entering the returns. From recent research conducted in Australia (2) it appears that the minimum inerting requirements are about 85% total incombustible content in the absence of methane ...
Accordingly, the suspended stone dust particles are able to inhibit flame propagation. The key benefit to all underground coal mines is in the ability to work inbye whilst continuing to stone dust. A patent covering the Airo-Dust® process has been approved in Australia under the Patent No. 2009326839.

Underground coal mines must review their current SHMS/SOP in relation to prevention of coal dust accumulation on mine roads, application of stone dust and sampling and analysis of roadway dust to identify whether the requirements and intent of the legislation is being achieved (Sections 300, 301, 302 and 303 of CMSHR and the Recognised Standard 5).
This report summarises the findings of assessments undertaken in relation to the risk of coal dust explosion in underground coal mines. These assessments commenced in October 2016, and to date have been completed at 16 mines. The targeted assessment is an in-depth look at the control measures for coal dust explosion and their implementation.
equipment. This includes underground coal and hard-rock mines, as well as surface mines, stone mines, and hard-rock tunnels. Because dust sampling has so many pitfalls, a chapter on methods used to sample dust is included. For those occasions when there is no practical engineering control, a chapter on respirators is also included.
