Considerations For Estimating Remote Operator Dust Exposure Using Fixed-Point Samples On Continuous Mining Sections, Jeffrey M. Listak, Gerrit V. R. Goodman, Robert A. Jankowski

U.S. Mine Ventilation Symposium

Respirable dust studies were conducted at several underground coal mining operations to evaluate and compare the dust measurements of fixed-point machine-mounted samples on a continuous miner and personal samples of the remote miner operator. Fixed-point sampling was conducted at the right rear corner of the continuous miner which corresponded to the traditional location of the operator's cab. Although it has been documented that higher concentrations of dust are present at the machine-mounted position, this work sought to determined whether a relationship exists between the concentrations at the fixed-point position and the dust levels experienced at the remote operator position and …
