Underground mine workers are exposed to a dust derived from mineral extraction operations and processes, the most harmful being called respirable dust (less than 5 um). The study measures the levels of respirable dust in 43 laboratories of a polymetallic underground mine in the central highlands of Peru. The measurements are made with a monitoring equipment with real-time reading, DustTrack 8533 - TSI. The health risk assessments for exposure to respirable dust were made analyzing both the activities and the work environment. The results of the evaluations found that 86% of the mining works (37 workers) had a dust concentration higher than an adjusted permissible limit of TLV_mina = 1.87mg / m3, corrected value based on the Brief-Scale method and the factor of Correction for geographical height. Likewise, the study offers the management of a new index of exposure called Rate Index of Dose (IVD), which shows the percentage of dose during one hour of working time, for each activity carried out inside the mine. The study that shows that the mine has a DIV of 23% / hour, in other words, it is affirmed that in 8 hours of work it has an exposure of 182% of dose, or 3.40 mg / m3 of concentration of average breathable dust The hygienic conditions of workers in the mine represent a high risk to occupational health with greater exposure, Performing Teachers and Performing Aides.
