This paper describes a computer analysis system used presently by the Bureau of Mines to analyze quickly and accurately large volumes of information obtained from real-time dust monitors during research studies. It substantially reduces the time necessary to perform various data analysis calculations and manipulations, including graphics. It also provides raw data files that can be transferred to other software packages for other required manipulations. A major benefit of the computer analysis system is the availability of information at the end of each test day. On-site analysis makes it possible to modify a study during the field evaluation process. The system does not alter the data collection process, other than requiring a small data logger instrument to be connected to each dust monitor. In some cases, the system has reduced manpower requirements during the data gathering phase. The system reduces the analysis time required by previous methods while improving many aspects of the data evaluation process. Although the paper deals solely with the use of the data analysis system with instantaneous dust monitoring equipment, it can be used with other monitoring equipment. The system has much flexibility and thus can be used in many different applications.
