Ecological Systems and Devices Annotation << Back The use of integrated index for assessing the environmental RISK of technological processes for the atmosphere adjacent to the PIT areas Papichev V.I. Proshlyakov A.N. The integrated index proposed for the assessment of environmental risk technological processes of the pit for the atmosphere adjacent areas that takes into account both the duration of the excess load in the period of assessment with the coefficient of frequency of excess and its intensity by means of the coefficient of frequency rate of excess. Assessment of risk carried out for processes that have the greatest load on the atmosphere: the transportation of rock mass by dump trucks and the production of mass explosions in the pit. The greatest load on the atmosphere at the moment of passing on the highway has the dump trucks Belaz-519, the smallest HD-1200. In magnitude the integrated index of risk, defined not only frequency rate of excess, but and the frequency of the events, the most risk Belaz-549. At the time of blasting the large load on the atmosphere has variant characterizing by lowest frequency explosions and consequently most mass of explosive and the volume of the rock. In magnitude of the integrated index, the greatest risk is the variant assuming exercise in the same amount of blasting that and other options, but with greater frequency.
