System for water collection that gravities into the old bed of the river Čehotina

Abstract

Functioning of the drainage system has a great importance for the efficient and continuous exploitation at the open pits. Modern exploitation is realized at the open pits with increasing depth and surface, so it is of a crucial importance to accept as much water as possible before it enters the open pit contour. By this way, the loading of a drainage system inside the open pit is greatly reduced, but it also prevents the negative effects of water on the massif. This paper, using the example of the open pit Potrlica, presents how the already existing system, which fully solves all problems in a dynamic environment such as surface mining of lignite, can be improved. Timely improvement of the system can greatly relieve the existing drainage system and improve the exploitation system.
