Rudničke vode olovo-cinkovih ležišta u rudnom polju „Blagodat“ u jugoistočnoj Srbiji
Nebojša Atanacković, Veselin Dragišić, Vladimir Živanović, Ivana Cvejić, Saša Stojadinović, Ivana Jocić (2022)Rudno polje Blagodat sa više ležišta i pojava olovo-cinkovih ruda nalazi se u krajnjem jugoistočnom delu Srbije, blizu granica sa Bugarskom i Severnom Makedonijom. Eksploatacija ovog resursa vrši se podzemno u okviru rudnika Grot, ranije Blagodat. Prilivi podzemnih (rudničkih) voda u jamske radove rudnika Grot su visoki i iznose oko 130 l/s (septembar 2019), što ga trenutno svrstava u najovodnjenije rudnike sa podzemnom eksploatacijom u Srbiji. Nezavisno od njih, iz obližnjeg potkopa P-1 u ležištu Kula, ističe još 25 ...Nebojša Atanacković, Veselin Dragišić, Vladimir Živanović, Ivana Cvejić, Saša Stojadinović, Ivana Jocić.

Fuzzy Model for Risk Assessment of Machinery Failures
The main goal of this research was the development of an algorithm for the implementation of negative risk parameters in a synthesis model for a risk level assessment for a specific machine used in the mining industry. Fuzzy sets and fuzzy logic theory, in combination with statistical methods, were applied to analyze the time picture state of the observed machine. Fuzzy logic is presented through fuzzy proposition and a fuzzy composition module. Using these tools, the symmetric position of the ...... the assessment contributes to the quality of the obtained results. Defining the membership degree of the obtained results, i.e., the membership function of a specific fuzzy set (minor, low, moderate, high, or very high), happens through defuzzification. The process of defuzzification can be applied ...
