Abstract
The main activity of open pit mining of aggregates are aggregates' exploitation of natural mineral deposits and its modification in order to obtain high-quality aggregates. The development of aggregate production is conditioned by a number of factors. The most important are: documented material resources, mining and manufacturing capabilities, the need of environmental protection (environmental aspects), the subordination of the plan of spatial development, formal and legal issues, as well as economic and financial aspects. While identifying and assessing the environmental impacts of manufacturing aggregates one may distinguish those environmental aspects that have or may have the greatest magnitude of the impact on the environment as a result of industrial activities. Manufacturers producing aggregates located in the areas covered by the special environmental protection require extra diligence in the conduct of mining activities for preservation of natural resources. The article discusses some main environmental aspects of the production of construction aggregates on the example of one of the largest producers of this material in Subcarpathian province of Poland. Environmental protection in production of aggregates may refer to four aspects: the use of natural resources, having excluded land from agriculture and forestry, land reclamation after exploitation, and use of energy from renewable energy sources. The economic and environmental impact of production volume of aggregates is evaluated by the index information capacity method and the method of graphs.
Highlights
As a result of the open pit mining activities, exploitation natural aggregates in building and road construction, several components the natural environment such as soil, terrain, water relations are violated
The economic and environmental impact of production volume of aggregates is evaluated by the index information capacity method and the method of graphs
Minimizing the influence of the environmental impact of the production of construction aggregates may be achieved primarily by implementation of modern technology and modernization of the existing mining equipment, which provide for more rational use of natural resources, while reducing significantly the emissions of pollutants into the environment
Summary
As a result of the open pit mining activities, exploitation natural aggregates in building and road construction, several components the natural environment such as soil, terrain, water relations are violated. Companies which produce aggregates distinguish those environmental aspects that may have the greatest magnitude of the impact on the environment as a result of their activities [1–5]. Manufacturers having produced aggregates located in the areas covered by the special environmental protection require extra diligence in the conduct of mining activities for the preservation of natural resources [4,5]. The article discusses some main environmental aspects of the production of construction aggregates on the example of one of the largest producers of this material in Subcarpathian province of Poland. The economic and environmental impact of production volume of aggregates is evaluated by the index information capacity method and the method of graphs
