• Description:
  The compliance sampling method for coal mine dust has not changed appreciably in the last 30 years. A call for more frequent sampling with immediately available results is leading to new instruments that may supplement or replace the existing sampler. This report discusses two such instruments that provide immediate results of dust levels. The first, called the Dust Dosimeter, is designed to supplement the existing compliance sampler. It uses the pressure drop across a filter to provide an inexpensive screening type of measurement. The Dust Dosimeter has been tested in the laboratory and a limited number of coal mines. Side by side testing has compared the Dust Dosimeters performance with personal coal mine samplers in triplicate area sample measurements. For all coal types tested the data were best described by a power function where AP = 1.43 mass 0.85, with a correlation coefficient of 0.73. Individual coal types have correlation coefficients greater than 0.91. Preliminary area sampling in non-diesel mines shows agreement with the laboratory data. The correlation in mines with diesel equipment was 10 to 20 times the response to coal particulate. Another sampler in the early stages of development is called the Personal Dust Monitor (PDM). Designed to give compliance quality accuracy, the PDM uses the frequency change of a vibrating element to measure dust and give immediate feedback of results. The technical components of the device are available and work is in progress to package the components into a person-wearable unit. [Description provided by NIOSH]
