4. CONCLUSION<br />Calculation of the obtained parameter<br />shows that the capacity pillar stope is directly<br />dependent on the thickness of coal<br />seams which are mined as well as the time<br />of performing the work operations of<br />blasting the over stope coal and loading on<br />a transport conveyor.<br />In relation to the existing used method<br />of pillar mining, this research has provided<br />the obtaining of over stope with<br />DDB separated by partial blasting charging,<br />resulting in a significant increase in<br />capacity and increase the safety of employees.<br />Further research has to be directed<br />to introduction the mechanized<br />loading with mobile machines, what will<br />further affect the increase in production<br />and productivity and productivity of pillar<br />mining.<br />Regarding to the natural-geological<br />conditions in the majority of coal deposits<br />of predisposed to the underground mining<br />system, it is concluded that the pillar mining<br />will further exist so for improvement<br />of financial performance of the mine, it is<br />necessary to continue with further studies<br />in the application of proposed solutions.<br />REFERENCES<br />[1] Ivković M., Miljanović J., Ivković<br />Lj., Tendency of development the<br />non-traditional system of<br />underground mining of coal seams,<br />Scientific-expert Symposium<br />"Energetika Srpske 98" with<br />international participation, Vrućica Spa<br />(pp. 809-813), 1998<br />[2] Ivković M., Miljanović J., Gagić D.,<br />Selection of mining method in the coal<br />deposits with limited reserves,<br />Scientific-expert Symposium "Energetika<br />Srpske 98" with international<br />participation, Vrućica Spa (pp. 836-<br />841), 1998<br />[3] Ivković M., Miljanović J., Bijelić V.,<br />Selection of mining system for a part<br />of the coal deposit "Ramići" Banja<br />Luka, provided for underground<br />mining, Scientific-expert Symposium<br />with international participation<br />"Possible aspects of exploitation, coal<br />preparation and combustion of the<br />Republic of Serbian", Vrućica Spa<br />(pp. 369-375), 1999<br />[4] Ivković M., Marić R., Miljanović J.,<br />Directions of restructuring the<br />underground coal mines with special<br />reference to the activation of new<br />deposits, Scientific symposium with<br />international participation, Energy of<br />Yugoslavia ENYU 2000, Zlatibor,<br />2000 (pp. 350-354)<br />[5] Miljanović J., Influential factors on the<br />realization of coal production in the<br />mines with underground mining of the<br />Republic of Serbia, Mining Engineering<br />No.1/2002, 1-12 Resavica (pp.26-31)<br />[6] Ivković M., Ljubojev M., Miljanović J.,<br />The effect of ground exploitation of<br />mineral resources on a damage of field<br />surface and built facilities, Third<br />International Conference on<br />Environmental Management<br />(ELEKTRA III), Herceg Novi 2004,<br />(pp.242-246), (in Serbian)<br />No 4, 2011. 79<br />MINING ENGINEERING
