lung tissue to that dust. In coal mining, both coal dust and respirable crystalline silica dust can cause lung diseases such as coal workers pneumoconiosis and silicosis. 1. The alveoli, or air sacs, are responsible for exchanging gases with the blood. They are located at the ends of each bronchiole. 11
A small readily portable stone duster that can be “speared” into a bulk bag or drum of stone dust and deliver it fast thanks to its properly engineered jet-pump.

Feb 04, 2011 Stone dust barriers were positioned at various points in roadways for this purpose. A simple wooden construction upon which stone dust was placed. In the event of an explosion these barriers would tip over and the stone dust dispersed. But another method of stone dusting was to actually spread the dust by hand.
Oct 13, 2020 INTRODUCTION. The recent reappearance of coal workers' pneumoconiosis (CWP) 1, 2 and emergence of artificial stone (AS)‐associated silicosis 3-5 has represented a failure of preventive systems to protect the respiratory health of workers in Australia. This resurgence of pneumoconiosis has occurred at a time when production has increased, mining techniques have been further mechanized …
Oct 13, 2020 Coal mine lung dust disease (CMDLD) and artificial stone (AS) silicosis are preventable diseases which have occurred in serious outbreaks in Australia recently. This has prompted a TSANZ review of Australia's approach to respiratory periodic health surveillance.
Sep 21, 2018 The risk of workers being exposed to hazardous dust particles should be controlled using the hierarchy of controls shown below. Controls should focus on higher-order controls (e.g. elimination, substitution and isolation of the hazard) as the most effective means of treating the hazard. Note: The Mining and Quarrying Safety and Health ...

Dec 21, 2015 The pithead and winding gear. When we reached the bottom of the shaft, 2600 feet down, and the long, gray, dimly-lit gallery stretched away into the distance, the dust that hung in the air – not coal-dust, my friend hastened to explain, but rock-dust scattered everywhere to smother the coal-dust and make fatal explosions less likely – made breathing difficult.
Mar 21, 2021 Coal dust explosions occur as a result of self-heating or spontaneous combustion. In underground coal mines coal dust explosions are a long-standing thermal dynamic hazard. Different physical and chemical processes contribute to coal dust explosions. The use of stone dust in mine roadways is a primary control against the explosion hazard.
Dec 09, 2011 Underground coal mining produces finely divided coal dust that deposits throughout the mine and serves as a source of combustible material for coal dust explosions. Limestone powder, known as rock dust, is spread throughout the mine workings on a regular basis. This rock dust serves to inert the coal dust when applied in the proper proportion.
The addition of stone (limestone) dust to roadway dust in an underground coal mine increases the Total Incombustible Content (TIC) to reduce the potential of the coal dust igniting and propagating an explosion. Coal dust explosions have been proven to be one of the most severe hazards in an underground coal mine hence as Queensland legislation requires the use of roadway stone dusting, …
Jun 21, 2011 Mine operators are required to apply rock dust in underground bituminous coal mines to reduce the explosion potential of coal dust and other dust generated during mining operations. Effective and frequent rock dust application is essential to protect miners from the potential of a coal dust explosion, or if one occurs, to reduce its severity.
This thesis discusses the development of a new type of stone dust barrier that has been implemented in South Africa and Australia and is considered to be better suited to modern-day mining practices.

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. (Total incombustibles in roadway are the stone dust plus moisture and ash in the coal). The requirement for stone ...
Application. This unit describes a participant’s skills and knowledge required to conduct stonedusting operations in Coal mining. This unit is appropriate for those working in operational roles. Licensing, legislative, regulatory and certification requirements that apply to this unit can vary between States, Territories and Industry sectors.
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.
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.
Jul 09, 2016 Plus it is from Australia, need I say more. ... Underground coal mines only have about 50% yield. A better solution is to seal a large fan at the mouth of the main shaft of abandoned coal mines to provide positive air pressure and light a fire in the mine. ...

Apr 23, 2021 underground coal mines [7–9]. In Australia, CWP was re-identified in 2015, after decades with no case reports [10]. Though recent prevalence of disease in Australia is not to the extent as seen in the US, it has nonetheless had a similar effect to spur new research on dust characteristics. Coal mine dust may contain a complex mixture of over ...

Jan 25, 2018 A QUEENSLAND company has invented and patented a hydrated polymer that might substantially reduce the cost of providing coal dust protection underground. Skillpro Services has developed a polymer that could help prevent coal explosions. At the moment stone dust is used as an inertant to prevent coal dust explosions in underground mines.
