Abstract This work presents the results of a four-year study on the determination of the range of soil groundwater drainage caused by the operation of the Tomisławice lignite open-cast mine. The performed analyses covered the area of 9600 ha which included 24 villages. It was found that operation of Tomisławice open-cast mine caused noticeable changes of soil groundwater level in the areas adjacent to the excavation. It consequently resulted in considerable changes in soil water regimes types on grassland areas but it did not always lead to soil degradation processes. However, the deterioration of soils hydrological conditions may cause disappearance of certain hydrophilous grass species.

Open Cast

Nowadays there is a tendency in the world industry to increase the number of open cast mines and the depth of work performed in them. In this regard, the problems of reliable and environmentally friendly transportation of extracted resources become especially urgent. Traditional motor vehicles is quite expensive, have problems with reliability and leads to a large gas pollution of the atmosphere, as well as the associated necessary stoppages of the open cast mine, which in turn leads to significant economic costs. The most optimal solution to these problems is the use of long conveyor lines for transportation. However, it is necessary to solve a number of problems one of them is related to the efficiency of the conveyor, which has a large length. This system needs to be controlled and monitored in real time. Thus, it is necessary to implement an automation system that meets all the specified requirements.
