Rock dusting to prevent coal dust explosions has been in widespread use in underground coal mines since the early 1900s. Underground coal mining technology has changed significantly over this ...

Eliminate your fugitive dust and make your operation safer and more profitable. When fugitive dust is present in the air, it can hurt your bottom line in several ways. Fugitive dust is a major risk factor for explosions. Coal dust explosions in underground coal mines are prevented by a generous appliion of rock dust (usually limestone).

 · Controlling airborne dust prior to deposition in the return would make current rock dusting practices more effective and reduce the risk of coaldustfueled explosions. The goal of this National Institute for Occupational Safety and Health study is to determine the potential of openair water sprays to reduce concentrations of airborne float coal dust, smaller than 75 µm in diameter, in ...

 · Rock dust consisting of ultrafine calcium carbonate particles is required in underground coal mines to suppress the potential for coal dust explosions. When the dust is applied in a moist mining atmosphere or placed in the mine in wet form, caking of the rock dust particles occurs which negatively effects dispersion of the dust during an event thereby creating the potential for an .

For this reason, rock dusts such as limestone dust are spread throughout coal mines to diminish the chances of coal dust explosions as well as to limit the extent of potential explosions, in a process known as rock dusting. Coal dust explosions can also begin independently of methane gas explosions. Frictional heat and sparks generated by mining equipment can ignite both methane gas .

Omya StoneDust is an exceptionally bright rock dusting product known to prevent coal dust explosions in underground mines. It is made from finely ground, brilliant white Calcium Carbonate to provide a safe, light working area. Omya StoneDust is a regulatory compliant solution that requires little maintenance between appliions.

Dust appliion rate is variable, making a HafcoVac Rock Duster a perfect solution for both trickle and bulk dusting operations. The most common size and configuration is our 55 gallon drum model (~550 lbs of Rock Dust capacity). We do offer custom configurations as well, please call to talk to a representative to design one for your needs.

 · Dust accumulations also exceeded permissible levels due to inadequate cleanup of coal dust; additionally, there was no crew in charge of rock dusting (inerting the coal dust with limestone or dolomite). These and many other factors contributed to the poor work conditions that continually existed in the Westray mine and made it the site of an incident waiting to happen. All of these substandard ...

While the Datong Coal Dust Columbian Coal Dust dolomite percentage increase is only 6% of its value when no methane is present ( 84 ¼ 89), the increase in 0 actual mass of dolomite for a given mass of coal dust is 0 200 400 600 800 1000 1200 1400 54%. This is caused by the exponential relationship Dust Concentration [g/m**3] observed when rock dust mass is plotted as a function of ...

 · Rock dusting involves applying pulverized limestone or another inert material throughout the mine to dilute the potential power of a coal dust explosion. The emergency temporary standard, which applies only to underground bituminous coal mines, requires mine operators to increase the total incombustible content of combined coal dust, rock dust and other dust to 80 percent from 65 .
