Abstract
To expedite the process of analyzing mine samples, the Pittsburgh Research Center has developed a portable optical reflectance rock dust meter capable of providing an in situ measurement of the rock dust concentration in coal mine samples. The goal of the current research is to develop a mathematical model of the relationship between optical reflectance, electrical conductance, moisture concentration, and rock dust concentration based on statistical analysis on data collected with the instrument and to estimate the uncertainty of the corrected rock dust concentration.
