Only a little save in the operation costs in this system will bring large profit for the mines. Due<br>to many investment periods, the capacity of both trucks and shovels in Cao Son surface coal mine is<br>different. This leads to the low efficiency and the difficulty in dispatching strategy for the mine. This<br>paper presents the current situation and selection of advanced dispatching strategy for increasing the<br>efficiency trucks and shovels at this surface coal mine. The results show the detailed match factor reflects<br>the state of each team of loader and trucks and should be use as the indicator for dispatching decision for<br>the heterogeneous truck and shovel fleet at Cao Son surface coal mine.</p&gt;}, number={2}, journal={Inżynieria Mineralna}, author={PHAM , Van Hoa and TRAN , Trung Chuyen and LE , Hong Anh and LE , Thi Thu Hoa and PHAM , Van Viet}, year={2021}, month={grudz.} }
