Chemical characteristics of the underground waters from the surroundings of the Brod-Gneotino digging, R. Macedonia

It is of essential importance to have information about the flow of the water and its characteristics when opening and preparing the diggings.The hydro-geological researches should give reliable documentation, and not until these researches are done that the opening and the exploitation of the diggings can start. The underground waters cause problems during the opening and processing of the mining objects which in certain cases can set an economic limit of the exploitation of the mineral raw material or completely stop the exploitation that has been started. In order to define the hydro-dynamical parameters for the wells, i.e. in order to determine the capacity of the watering system (separate capacity for each well which will operate in a group) in all the well it was performed a separate pumping testing. At the end of the testing process, samples of water were taken from each well in order to make a complete physical-chemical analysis of the water. This paper presents the received results from the chemical content of the underground waters from the surrounding of the Brod-Gneotino digging
