Rock Dust Partnership
This partnership addresses issues about using rock dust to prevent coal dust explosions.
The Pittsburgh Mining Research Division will host a virtual partnership meeting in the fall of 2020, tentatively scheduled for Sept. 30 from 8:30 to 11:30 a.m. ET. Meeting information and any registration details will be provided at a later date.
Large-scale testing of a foamed rock dust applied wet and allowed to dry was conducted at the Central Mining Institute in Poland in 2019. Due to COVID-19 related issues, a final report of results has been delayed, but will be completed in the coming months.
Due to COVID-19 related concerns, site access to laboratories has been severely limited and efforts to establish the dust dispersion chamber as a NIOSH standard method are on hold. Testing will resume once regular access is permitted.
