The quality of the environment in the Rosia of Jiu quarry as a result of the use of Caterpillar 323D L and 323D LN excavators

Abstract

This paper studies how the activity of hydraulic excavators found in the Rosia quarry of Jiu affects the environment. For this study we chose the Caterpillar 323D L and 323 D LN hydraulic excavators. The study took place over a period of 30 days. These days we have collected data on the noise level and the level of PM 10 particles in the quarry. Caterpillar equipment not only helps to build a better world, but also helps to preserve the environment, which is so fragile today. The evolution of excavators has led to a more efficient way of working both in terms of production, costs and effects on the environment. Their efficient way of working has led to an increase in production and a decrease in the level of pollution in the Rosia Quarry area.
