Sampling strategies, which can be used in coal mines with gca ram (respirable aerosol monitor) instantaneous dust sampling instruments, have been developed to provide information that cannot be obtained with full-shift gravimetric sampling. As part of a Bureau of Mines dust control research contract, gca ram instruments were used on one longwall face to determine dust levels when using two different water spray systems. Sampling on the longwall face was conducted adjacent to and upwind of the shearer to estimate the shearer operator's exposure. A stationary face location was also sampled to profile dust levels near the shearer. Results of the sampling were compared to determine the relative dust control effectiveness of each water spray system.
