Abstract

The mining activities are indicating large number of negative effects on the living environment. The nature of these negative effects depends from the mineral raw material that is exploited, and her further processing. The coal, salt, poly-metals (colored and noble) mines, and nuclear raw materials are the main polluters. The exploitation of building stone, architectonic stone, send and grit stone although wider developed and numerous, is less significant from the chemical point of pollution.
Like the surface diggings, the underground diggings are under the sea surface, and very often big sewage capacities are needed to enable progress in the mining process.
The influence that mining activities have on the living environment is appearing almost in every phase of the mining cycle, from the preparation of the locality, trough digging, separation and processing the ore.
Mining water are usually high mineralized, and are having low pH value (to 3), high contents of heavy metals like plumbum, zinc, cuprum, manganese, cadmium, cobalt, nickel, aluminum and sulfates. When water that leaks on the surface or underground, and in the same time expose the ore that contains sulfides, comes in contact with the air, sulfide acid is creating in the water, what is familiar as the natural process of creating mineral water (acetic water). The mining water polluted with heavy metals is endangering water resources, ground, people, building infrastructure that are near polluted environment. In this paper it will be shown, how the mining activity influence the water, air, environment and the appearance of noise.
