Abstract

This research was conducted at PT Harvest Construction Mining Services which is engaged in mining, especially in nickel ore mining as a mining consultant. Which is located in Mandiodo Village, Mandiodo District, North Konawe Regency, Southeast Sulawesi. This study aims to create a pit design and mining sequence design at PT Harvest Construction Mining Services, to make a production schedule based on daily ore production targets. Based on the results of the research, the pit limit was designed based on the estimation results of the block model with the parameters of bench height of 5 m, width of berm 2 m, CoG of 1.5%, and a minimum stripping ratio value of 1:3. Based on the pit limit design, the opening volume is 371,445 m3. Based on the mining pit limit, the pit limit design is divided into several smaller units using mining software. The results of the analysis of the distribution of mining sequences obtained four mining periods with each period per quarter. The first mining sequence obtained a total ore of 67,215 tons of overburden 104.383 tons, the second sequence obtained a total of 71,814 tons of ore with 39,081 tons of overburden, the third sequence with 72,735 tons of ore and 40,547 tons of overburden. The fourth sequence, which is the pit limit of mining, obtained a total of 67,033 tons of ore with a total overburden of 110,100 tons. The total ore to be mined is 278,797 tons.

Abstract

Coal characterization is very heterogeneous chemically and physically, even within one seam there can be significant differences. Although some areas have coal, the characteristics of coal in one area are not necessarily the same as coal in other areas. This research was conducted to determine the coal rank based on calorific value, coal grade and coal characteristics of Mallawa Formation. This research was conducted using field data collection methods directly in the field in the form of coal samples, outcrop geometry data which were then subjected to laboratory analysis in the form of proximate, sulfur and caloric tests, and analyzing the relationship between total sulfur content in coal and coal ash content. The results showed that the coal rank based on coal calorles is in sub bituminous (low rank), coal grade in very low grade coal, with an average moisture content of 7.78%, average ash content of 39.99%, volatile matter 32.85% and average fixed carbon 19.39 cal/gr, and has a high sulfur content of 2,13%. There is a strong relationship between ash and sulfur content in coal with an R²value of 0 8238.

Abstract

The main function of the mine road is to support the smooth of mining operation, especially in transportation activities, so the good mine road is necessary to design to improve hauling productivity. This research aimed to determine the ideal road geometry for the transportation activities. The data used in this research are topography map, transportation equipment specification data, SOP (standard operational procedure) of road design, and road geometry data. Data processing is conducted to make the calculation of road geometry using rational formula, then based on the result of the calculation, the design of mining road is made. The results of the research showed that the minimum road widths for the straight road are 22 m and for the bend are 28 m, then have the grade of 10% or 3.6°, have the cross slope with height of 3%, and for the bend with width 28 m. The good superelevation used is 6% m. In conclusion, the geometry of mine road at PT. Vale Indonesia, Tbk has been the ideal for fulfilling the hauling activities.
