Abstract

This paper presents the results of the tests conducted with the ZWILKOP ZW-10 dust control preparation (Patent P. 394235) used in the air and water sprinkler systems at mining facilities. The tests aimed to assess the inhalation exposure of the mining personnel to respirable/1 and inhalable2/dust fraction and to chemical agents when using ZWILKOP ZW-10 (MSDS 2013) preparation. This publication contains the results of the measurements performed to evaluate concentrations of the hazardous chemical substances: 2-(2-butoxyethoxy)ethanol and 2-ethylhexan-1-ol, which are the components of the ZWILKOP ZW-10 preparation, and respirable1/ and inhalable2/ dust fractions at mining personnel workstations. The tests were performed with the use of the mist systems during extraction works in: • Borynia - Zofiówka - Jastrzębie Hard Coal Mine, inclined drift C31, seam 420/1-2; • Budryk S.A. Hard Coal Mine, seam 341, wall Dz-1, where hard coal type 35.2(PN-68/G-97002) was extracted; • Pokój Hard Coal Mine, wall 219, seam 502, where hard coal type 34.1 (PN-68/G-97002) was extracted; • Halemba Hard Coal Mine, wall 5, seam 507/H, where hard coal type 34.2 (PN-68/G-97002) was extracted. The assessment of the prevention of respiratory dust hazards affecting the personnel with the use of the ZWILKOP ZW-10 preparation was conducted in mines selected depending on the type and classification of extracted coal (PN-68/G-97002).
