Abstract:

Purpose. To carry out laboratory and in the field studies on the dust respirator protective efficiency improvement.

Methodology. Laboratory estimation of the penetration coefficient of the dust filtering respirators has been carried out by the method described in DSTU EN 143-2002. In the field estimation of the dust concentration in the air before and after filtering by the respirator has been carried out according to the guidelines “Manual on dust Concentration and Dust Load Estimation in Mines.”

Findings. The respirator protective efficiency in production environment is high at the start of its use. Its performance is commeasurable with the same in laboratory environment when air leaks-in through the shutter. But sooner or later the dust accumulation, breathing resistance increase, sleeping of half-mask and necessity to talk during the work lead to its degradation due to the unfiltered air inflow through the shutter contact line leak.

Originality. Authors have determined that the respirator penetration coefficient degrades as the dust content rises because of sharp reduction of the size of filter pore spaces caused by deposition of coarse particles of coal dust between the fibers, breathing resistance increase and additional dust inflow through shutter contact line.

Practical value. Authors have determined main causes of the respirator protective efficiency degradation in the production environment of coal mines.
