A comprehensive survey of respirable dust and respirable silica in Ontario gold mines was conducted by the Ontario Ministry of Labor during 1978-1979.
Bharath Belle, How relevant are engineering samples in the management of personal dust exposure?, in Naj Aziz and Bob Kininmonth (eds.), Proceedings of the 17th Coal Operators' Conference, Mining Engineering, University of Wollongong, 8-10 February 2017, 395-410.
"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 .

Simultaneous airborne dust samples were taken with three types of instruments: konimeter, thermal precipitator and dosimeter (personal sampler with membrane filter) in eight asbestos mines producing four types of asbestos (Cape crocidolite, Transvaal crocidolite, amosite and chrysotile).
sampling pump and filter cassette (pre-weighed) to determine dust concentrations in the mine atmosphere. Gravimetric sampling is used to determine personal exposure (breathing zone) and can also be used to screen for other mineral dusts that may require particle counting to determine compliance, such as the six silicates specified in Chapter 6

operations in the mines were made using the konimeter. GCA respirable dust monitoring The survey of environmental conditions in 12 operating mines was made in 1976. This was a special sunzey, where more than 400 operations were sampled with both the GCA direct reading gravimetric dust sampler and the konimeter.
Aug 21, 2019· Extensive PMRD laboratory and in-mine testing have demonstrated that the PDM is an accurate dust sampler suitable for underground use. Since 2016, MSHA has required mine operators to use the PDM for compliance dust sampling as part of its most recent respirable dust regulation.
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.

Reported dust exposure measurements at the two mines were of a cross-sectional design. At each mine, bulk and personal respirable dust samples were collected at scheduled areas. Scheduled areas are production areas of the mine where mining regulations of the Zambian mining regulatory authorities apply. In these areas, the main production
Dec 15, 2018· Many individual snap konimeter samples taken at the Colonial Mill in the last 5 years of operation recorded as 1000+ ppcc, and notation of considerable quantities of asbestos fibres. In 1960 comparative dust sampling was conducted between a midget impinger (10 min samples) and a konimeter (4 snap shots during the 10 min).
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.
