17/06/2019· As a part of these rock dusting best practices, dispersion of coal dust/rock dust relative to ventilation practices also needs to be further investigated. The work in this topic area is supported by the NIOSH Mining Fire Fighting and Prevention program. See the NIOSH Mining Products page for software, guides, training materials or other items ...

CDC - Mining Feature - New Rock Dusting Standard - NIOSH

To reduce the danger of a dust explosion, mine operators commonly inert the coal dust by adding rock dust - usually limestone dust - which is incombustible (not prone to burning or exploding). In view of current coal mining practices, NIOSH's Office of Mine Safety and Health Research (OMSHR) completed research addressing best practices for rock dusting in coal mines, re-examining past assumptions.

CDC - Mining - Rock Dusting Practices - NIOSH

Rock dusting sampling practices. This report discusses research that was conducted in the NIOSH laboratories, experimental mine, and in operating mines to evaluate the potential explosion hazard associated with excessive coal dust accumulating on elevated surfaces, the efficacy of wet rock dusting, and the need for mines to develop ...

CDC - Mining - Rock Dusting Considerations in …

Rock dusting to prevent coal dust explosions has been in widespread use in U.S. underground coal mines since the early 1900s. Underground coal mining technology has changed significantly over this same time period, becoming highly mechanized and produces finer coal dust particles which are more explosive. Despite the advances in mining technology, mine-wide dust sampling practices have ...

Development of a New Hydrophobic Rock Dust | Coal Age

In September 2012, NIOSH published on their website (www.cdc.gov) that they had identified a dispersibility problem involving the effectiveness of rock dust within the mine entries when that rock dust has become wet and then dried; i.e., the rock dust forms a hardened cake that will not disperse. “In order to prevent rock dust from caking, OMSHR was investigating the use of additives that ...

Welcome to CDC stacks

Even with enhancements to the rock dusting application methods and equipment, coal mining operations still experience compliance issues associated with meeting the current total incombustible content (TIC) requirement of at least 80% for all mine dust samples.
