Abstract

Loading and transporting overburden is one of the activities carried out in nickel mining by moving overburden from the mining front to the disposal site. Research Objectives: 1) Determine the efficiency of loading and transporting equipment in loading and transporting overburden. 2) The production capacity of loading and transporting equipment used in loading and transporting overburden. 3) The compatibility factor between loading and transporting equipment used in loading and transporting overburden. The methods used in this study were interviews and observation. The interview method was conducted with people in the company area regarding data to be collected at the company itself. Then, the observation method involved directly observing the data to be collected at the company. The results achieved in this study are the work efficiency value for loading equipment is 83% and for transport equipment is 83%, the production of 1 unit of loading equipment is 37,788.16 Bcm/month and 4 units of transport equipment is 37,333.6 Bcm/month so that it has met the target, the work harmony factor of loading equipment and transport equipment is 0.98 so that MF<1, which means that the transport equipment is working fully and the loading equipment still has waiting time. It is necessary to add transport equipment so that the loading equipment does not have waiting time.

Abstract

The purpose of this study was to determine the dominance size of the settling pond, calculate the discharge and the runoff volume of the Keuno Block B Pit. The purpose of making this settling pond is to accommodate runoff water flow that will enter the mining area in Pit B of the Keuno Block. The research method used is descriptive research to provide information about facts and phenomena that occur at the research site. Data was collected through field observations, interviews, and document studies. Association obtained 1) Water entering the Pit B Block of Keuno in the form of runoff water with a discharge of 2,72 m3 / sec at DTH, 0,609 m3 / sec at DTH II, and 1,081 m3 / sec at DTH III 1,069 m3 / sec. 2) From the results of runoff discharge calculations, the dimensions of the first settling pond plan are made: Water Discharge (Q) = 2,72 m3 / sec, Pool Volume (V) = 1000 m3, Pool Length I ( P) = 35 m, Pool Length II (P) 30 m, Pool length III (P) 25 m. Pool side width I (L) = 24 m, Pool side width II (L) 22 m, Pool side width (L) = 20 m. Pool Depth (d) = 5 m.
