The application of coal transfer through belt conveyor usually use for transfering coal from or to stockpile. Coal storation in stockpile that is transferred through belt conveyor is done after coal is directly transported from mine coal or after it crushed and washed in the washing stationary first, the other way can be stocked at port before it's transported to bulk carrier. <br /> <br /> <br /> Analysis of the influence of belt conveyor and stockpile size and then the relation to the packing density of a coal stockpile is needed. In this study, analysis of belt conveyor is conducted by making the variation of conveyor velocity, belt width, ang troughing angle to get the variation of belt conveyor capacity and then <br /> <br /> <br /> analysis of the influence of variation of conveyor speed to the packing density of a coal stockpile is conducted. Beside that, analysis of stockpile is conducted by making a variation to stockpile size , such as height of stockpile and width of stockpile to get a variation of stockpile capacity, and then analysis of the influence of height of coal stockpile to coal packing density in stockpile. <br /> <br /> <br /> From the analysis that is conducted to belt conveyor, the maximum and minimum value of belt capacity that are in tools is available. Minimum transport capacity of belt capacity is 752.59 tph at troughing angle 20 degree, stockpile width 1 m, and conveyor speed 2 m/s and value of maximum transport capacity of belt conveyor is 3,603.87 tph, for troughing angle 45 degree, stockpile width 1.4 m and conveyor speed 4 m/s For the analysis of stockpile, we get variation of stockpile capacity from 1,181.03 to 20,285.79 ton for conveyor speed 2 to 4 m/s, stockpile height 2.7 to 10.8 m and stockpile width 6.72 to 26.88 m and the variation of stockpile capacity are from 24,888.29 to 413,484.89 ton for conveyor speed 2 to 4 m/s, stockpile height 12 to 43 m and stockpile width 29.64 to 107.5. By comparing transport capacity value of belt conveyor that is got from variatio simulation and actual data from field so it can be concluded that actual operation capacity in the real condition are different, that is about 72% of simulating capacity The analysis of packing density give a conclusion that the increasing of stockpile height will increase packing density, besides conveyor speed can increase and decrease packing density. <br /> <br /> <br /> The result of optimum packing density is 0.899 for stockpile height 19,84 m and value of optimum packing density is 0,8064 at height of disengagement point 21,26 m and conveyor speed at 4 m/s.
