NTIS: PB/83-232207 :49 pages
Field studies were conducted on eight continuous miner sections and two longwall sections operating in five different coal seams. Data and information on dust concentrations and engineering dust controls were acquired for normal operations. Dust concentrations at the mine operator and longwall face locations were evaluated using gravimetric samplers and instantaneous dust monitors. Engineering dust controls that were evaluated included airflow rates and/or velocities, waterflow rates and/or pressures, brattice distances, and face cutting times or rates. An analysis of the data acquired during the field studies was performed using multiple regression methods. Several relationships describing the influence of dust control parameters upon dust levels of mining equipment operators are presented. The effects of engineering dust controls upon miner operator dust concentration may be expected to be different from mine to mine and sometimes from section to section. A consistent relationship between the dust concentration variations and dust control variations was not observed.
