After their consideration of the " PRU Hand Pump " as a coal face dust sampler [this Bulletin, 1958, v 33, 668] the authors continue with a critical assessment of the " British Konimeter " as a dust sampling instrument in preparatory work, where both coal and rock may be present They show that with the standard technique of counting, the ....
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...

Currently, mine dust sampler pumps draw 22 L/min of air through a mini-cyclone, which separates the airborne dust and collects only the fraction of respirable dust (<10 µm) on a pre-weighed filter...
ter, an instantaneous dust sampler having a sampling duration of approximately one-third of a second The collected dust sample was counted under a microscope and expressed as the number of particles per unit volume of air (particles per cubic centimeter) The ear-liest available konimeter dust data in Ontario date back to 1940 However, the data of the 1940s and 1950s were very sparse and ....

Whereas in the United States impinger measurements with counting of single particles (“mppcf”), where the base of the recalculation process, in Australia konimeter data and later gravimetric sampling (“total dust” and respirable dust) were used...
German uranium mining industry was performed in order to provide information about the exposure situation of the miners towards respirable dust, inhalable dust, crystalline silica and heavy metals It should provide the necessary information for legal compensation of miners with potential industrial diseases as well as for epidemiological research Methods Extensive side-by-side measurements ....

In South Africa, the sampling rate used with 10 mm cyclone personal samplers is 19 l/min, while dust samples collected in the USA use a sampling rate of 17 l/min (ACGIH, 2002) Thus, the definitions of fractions are not the same and should be taken into account when making comparisons...
