Influence of Mining Exploitation on Soil Chemistry on the Example of Ostrava-Karviná Hard Coal District

This paper presents the results of soil testing in selected sites of Ostrava city. Soil samples were collected from nine parks in Ostrava from three different depths using a drill. The sites from which the samples were collected are areas near trees and open space. Each of them is located in a different part of the city and is affected by different types of pollution. Soil is one of the resources that very often cannot be reclaimed. This process is spread over time, and restoring land to public use without negative human impact is very costly and long-lasting. The analysis will allow to determine the impact of mining operations on soils in selected places of Ostrava city. The results are compared with the maximum permissible concentrations of harmful elements according to the Regulation of the Ministry of Environment on land protection.
