  • Definition of konimeter mindat glossary

    Apparatus used to measure dust in mine atmosphere. A measured volume of air is drawn through a jet so as to impinge on a glass surface coated with glycerin jelly. The adherent dust is then examined and the particles are counted under the microscope. Also called Zeiss konimeter. See Also: dust sampling

    He said that for the last 30 years dust sampling has been an important subject in Witwatersrand mining, and the great success achieved in decreasing the incidence of silicosis on these fields has perhaps been due in no small measure to the use of the sugar tube and that small instrument, the Konimeter.

  • Personal Gravimetric Dust Sampling for the South African

    A review is given of progress made to- wards the development of personal gravimetric dust sampling for risk assessment on South African gold mines. The present strategy is critically examined on the basis of principles for assessing health hazard from dust exposure. Reasons are advanced for replacing the konimeter with a gravimetric system based on...

  • Dust control in mining industry and some aspects of silicosis

    Dust Control in the Y~ne Sampling and Counting Procedure The deleterious effect on human beings of dust in mine air is well-known. It is the duty of engineers, therefore, to take measures to elimi-nate it. It is now definitely established that of all the various types of dust encountered in mine air, silica dust is the most harmful. This dust, if inhaled over a period of time, causes the

  • The risk of pulmonary tuberculosis in underground copper

    23/08/2016· Pulmonary tuberculosis (PTB) among underground miners exposed to silica remains a global problem. Although well described in gold and coal mining, risk in other mining entities are not as well documented. This study aims to determine dust-related dose response risk for PTB among underground miners exposed to silica dust in Zambia's copper mines.
