T arget production will be achieve optimally, if all the factor that affect the valueof production are evaluated in order to meet the level of efficient productivity.One of the factor that affect the achievement of production target is roadgeometry, where conveyance will pass through from loading point to disposalarea. This research will be evaluating road geometry, so that the road geometry isobtained that matches the the capabilities of the equipment so as to achieve themaximum level of productivity. With the proper road geometry that theconveyance pass, it is hoped that the maximum productivity value of thetransportation equipment will be achieved and the achievement of thepredetermined production target. From this research, the researcher obtainedthat the width of the overburden haul road still below the company’s standard,with the average of straight road is 15,71 m and the turning road is 14,61 m.From the field data, the average mining road grade is 3.19%, which is still inaccordance with the standards set by the company. After simulating the width ofhaul road according to company’s regulation, become 18 meter for the straightroad and 20,5 meter for the turning road, from that there’s an improvement ofcycle time from the actual 13,62 minute become 12,24 minute. Because of thatimprovement, cause the improvement of production from 5009,63 BCM to 6354,59BCM.
