The purpose of this study was to conduct research in several areas of instrumentation used to determine the quantity of respirable dust in a mining atmosphere. The study was divided into eight tasks including (1) the feasibility of using a dichotomous impactor in conjunction with two photometers for a machine-mounted dust monitor, (2) development of a laser diode optical particle counter, (3) development of an instrument evaluation chamber, (4) instrument evaluations and calibrations, (5) development of a new personal respirable dust sampler, (6) development of a uniform deposit cascade impactor, (7) inertial impactor calibrations and theoretical investigations, and (8) descriptions of field studies.
