Abstract

The negative effect made by mining enterprises on the natural environment has complex origination. The intensive pollution is observed because of the influence of mineral deposits open-pit mining on the atmosphere, water resources and landscape complexes. Complex processes of environmental anthropogenic changes caused by open pits’ operations have brought to light the problem of surface water pollution near large mining segments. Industrial wastewater of mining enterprises has a significant impact on the natural environment. In connection with the continuous and significant increase in the volume of mining, the amount of wastewater from mines, quarries and processing plants is constantly increasing. The main components of wastewater from operating mining enterprises are mine (quarry) waters, as well as runoff from atmospheric waters polluted by water erosion of dumps and mineral stacks. The paper describes the possible ways of quarry wastewater purifying – using hydrocyclones and artificial filtering arrays made from overburden rock.

The main constituent of mine waters are the waters coming from aquifers and from the surface
Especially in coal mines, the amount of accompanying water rises sharply due to sudden breakthroughs of water from aquifers, from previously dumped workings and surface water bodies, as well as through flood and stormwater breakouts

Summary

Introduction

The main constituent of mine (quarry) waters are the waters coming from aquifers (the underground origin of water) and from the surface (atmospheric waters). Technological waters, which volume is relatively low in traditional methods of underground mining (rarely exceeds 10% of the total volume of mine waters), are contaminated with fine dispersed mineral particles and chemical solutions used in drilling wells, as well as in dust suppression. Technological waters in the open-pit mining of ore, coal and non-metallic deposits are used in moderate quantities for drilling wells, dust suppression and in significant quantities for hydro-mining and hydrotransport. Industrial sewage of mining enterprises can be characterized by high acidity, alkalinity, salinity, stiffness and turbidity They are contaminated with solid and colloidal particles of rocks and minerals; various chemical compounds; contain organic and bacterial contaminants [1,2]. Expanding the use of self-propelled equipment in underground excavations, and in open-pit mines - a powerful transport and technological equipment with diesel engines [3,4], has led to an increase in the pollution of mine and quarry waters with oil products
