Abstract

"In this modern age, the scientific and technological developments have advanced mechanized mining to the status wherein the attendant dust problems have reached very serious hazard proportions. The significant roles, which have been perfected for the Zeiss konimeter and the midget impinger, in evaluating dust concentrations and thereby revealing possible improvements in making the atmospheric conditions safer, cannot be over emphasized.

While introducing the subject of this paper in the first chapter, the author has presented a historical resume, wherein he pointed out that performances of these instruments have not been correlated in the past. However, the work reported on each individual mechanism has been reviewed in chapter two.

The above instruments and their standard techniques for measuring dust concentrations are described in chapter three and the experimental procedures based on these techniques and the data collected during the investigation, are presented in chapter four.

The data are analysed and discussed in chapter five whereby it is revealed that, due to the inherent nature of the dust particles in creating rapid fluctuations and due to great divergence in sampling characteristics of the instruments, no constant ratio or conversion factor from dust concentration measurements of one instrument to equal values for another, has been possible. The relative performance of these instruments is presented graphically "--Abstract, page iv.
