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.
Sabinet | Mine air analysis on the Reef in the early 1900s . He was heavily involved in the gold mining . airsampling techniques for dust analysis used in his time, namely the sugar tube method and the konimeter. .
dust was made using a konimeter since 1958. The konimeter has ... coal mine dust personal sampler, which was extensively used in USA coal mines in conjunction with a 10 mm nylon cyclone

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...
Aug 21, 2019· Extensive PMRD laboratory and inmine 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.
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).
During earlier investigations in coal mines the author and his colleagues observed that there were limitations to the use Of the konimeter for sampling airborne coal dust. The konimeter has been used for dust investigations in British mines, and is still being used. Chubb remarks that if the main object of its use is to estimate the free silica hazard the instrument may be suitable, but that ...

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.
ter, an instantaneous dust sampler having a sampling duration of approximately onethird 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 earliest available konimeter dust data in Ontario date back to 1940. However, the ...
"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 .
Dec 01, 1977· Abstract. 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 .
Reported dust exposure measurements at the two mines were of a crosssectional 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 .
