We will monitor the fallout 

In mining operations, particle emissions tend to be caused by heavy traffic and machinery, mining, loading, and the crushing of ore and waste rock as well as the storage of tailings. 

Concentrations of inhaled particles have been measured at Hannukainen and Rautuvaara, using automatic analysers in continuous operation. The purpose of the measurements was to survey basic air quality at the mining sites of Hannukainen and Rautuvaara, before the potential commencement of new mining operations. 

With regard to the piles of waste rock, dust emissions will tend to occur in the summer time, because the waste rock is covered in snow in winter. In the summer, dust emissions will be minimised by the adequately coarse size distribution of the material being dumped and through watering. In addition, dust emissions can be minimised so that the part of the waste rock area already finished is landscaped. 

Heat will be generated by the blasting, due to which the snow will melt and absorb dust. The amounts of dust created during blasting will be relatively small compared to the overall scale of the mine, and occur for only a short period of time. Their proportion of total dust emissions will be small. The dust reduction measures will be specified in greater detail as the planning work progresses, and during production. At the start of the operation, we will monitor the fallout with dust collectors.
