This work sets out the methodology and presents the calculation results of the amount of carbon dioxide emitted into the atmosphere of the BelAz dump truck at the Open Pit "Turija" BCM Banovići d.d., based on the fuel consumption monitoring data. Properly determined fuel consumption enables the calculation of the amount of carbon dioxide emitted and preventive measures, as well as the choice of its reduction strategy. Data collection took six months, then the data were analyzed, and thus the results were given for all dump trucks by months. Key words: fuel, open pit mining, BelAz dump truck, maintenance, Coal Mine Banovići, carbon dioxide

The review and analysis of a timeline work and stoppage/failure of transportational complex on separation in SC coal mine „Gračanica“ LLC Gornji Vakuf – Uskoplje has been given in this work. The work is based on collecting and analysing data. Collecting data lasted for one year and it is analysed and shown in this work. Rightfully determined the state of work and stoppage/failure, allows precautions and choice of strategy for the next period. Conclusions about which stoppage/failure affected the stoppage of transportational system and separation in full are derived from the research, and based on those conclusions, suggestions about activities which would minimize these stoppages on acceptable value are given. Key words: mine, coal, effective work, stoppage, failure, transportational complex, separation, belt conveyor, scraper.

This work sets out the methodology and presents the calculation results of fuel consumption of the BelAz dump trucks at the Open Pit "Turija" of the Brown Coal Mine Banovići itd. based on monitoring data. Properly determined fuel consumption allows the preventive measures and selection of strategy to reduce it. Data collection took six months, the data were analyzed, and thus the results by month of all dump trucks were presented.

This paper sets out the methodology and presents the results of calculation the efficiency of transport system in separation of the OP "Dimnjače", based on the data of monitoring the operating time and downtime/failure. Properly determined state of operation of the transport system, allows preventive measures and selection of maintenance strategy. Data collection lasted a year, and the data were analyzed, and thus the results are given by month for the transport system as a whole.

This paper will demonstrate the methodology and results of analysis the stationary phenomena upon gravitational pipeline transport of brine from the Salt Mine Tuzla to the ultimate consumer. Moreover, it will provide the analysis of reciprocal effects of flow, change in diameter, speed of hydraulic ascent, loss of pressure and density of brine.

This work presents a methodology of data collecting and processing from the load and fuel control system SKZiT, installed on BelAZ 75131 trucks, owned by the Brown Coal Mine "Banovici" in Banovici. There is also a methodology of display the achieved operating parameters. Transport of coal and overburden is performed by these trucks. Total of eleven trucks has processors. Conclusions about working time, length of crossed routes, quantity of transported load, achieved cycles, etc. Can be presented by data processing.
