Limestone Makes for Cleaner Coal. CE Concrete saw a window of opportunity in the 1980''s to join the greener power generation. With the help from wheel loaders and articulated haulers they are able to contribute to the greener power movement by extracting limestone that is used by coal power plants to scrub exhaust emissions and for dust control in underground coal mines to prevent explosions.
§ Maintenance of incombustible content of rock dust. Where rock dust is required to be applied, it shall be distributed upon the top, floor, and sides of all underground areas of a coal mine and maintained in such quantities that the incombustible content of the combined coal dust, rock dust, and other dust shall be not less than 80 ...

approach to elimination of the coal dust problem is to add stone dust to the roof, ribs and floor to render the coal dust inert. In addition, many mines use explosion barriers which are designed to be activated by the pressure wave in front of an explosion, and flood the area with either water or stone dust, which renders any suspended dust inert.

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).
Stone dust tends to fall out earlier than coal dust due to its coarser size and higher density. This causes the incombustible content to rise away from the duster. Almost all of the stone dust distributed by the trickle duster was seen to fallout within 100 to 150m of the source.
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 ...
