Abstract

Indonesia has many coal resources that can play an important role in meeting domestic energy needs. The mining system applied by PT Bukit Asam Tbk is open mining with open pit mining method. The mining industry is one of the industries that is capital intensive, technology intensive, and very risky. One of the important things in mining activities is coal transportation to achieve production targets. Some factors that affect the conveyance cannot operate optimally include narrow haul road conditions so that when the conveyance passes one of the conveyances must stop, bumpy road conditions so that during transportation a lot of material is scattered. the purpose of this study is to control the condition of the haul road to be traversed so that production targets and operator safety in the mining area can be maintained properly. The width of the haul road in straight and bend conditions is different, the width of the mine road on the bend is always made larger than the straight road. This is intended to anticipate deviations in haul road width caused by the angle formed by the front wheels with the truck body when crossing the curve. A good mine road has a transverse slope between 20 mm/m and 40 mm/m or 2% to 4% for every 1m of mine haul road width. From the results of the calculations that have been carried out, the haul road geometry on the TS +35 to TLS 2 road has a length of 3,125 m by making as many as 5 segments, namely 10 straight road sections and 6 bend road segments. On the straight road there are 2 sections whose road width still does not meet the standards of Kepmen No. 1827/K/30/MEM/2018, which will have an impact on the performance of the conveyance used and can cause human error when vehicles pass each other. Meanwhile, the width of the bend road and the cross slope value on several road sections have met the road standards.

Abstract

PT Bukit Asam (Persero) Tbk is a State-Owned Enterprise (BUMN) which was founded on March 2 1981 located in Tanjung Enim, South Sumatera. The purpose of production activities is to produce minerals that have a price or selling value. In coal production activities there are two productions that can be carried out, namely coal production and overburden production. PT Bukit Asam Tbk. implementing open-pit mining methods. The mining method in Pit 2 Banko Barat uses the strip mining method, because this method is used in coal deposits with a relatively small slope (dip), the slope (dip) in Pit 2 Banko Barat is N200OE/25O. Mining activities in Pit 2 Banko Barat are still being carried out are mining (exploitation), processing, marketing and post-mining activities. In coal mining activities, PT Bukit Asam Tbk. using a shovel PC 3000 earth digging tool and a Belaz transportation tool. Apart from loading and unloading excavation equipment as the main mining equipment, there is also supporting equipment such as motor graders, bulldozers, water tanks and fuel tanks to obtain optimal and maximum production results. In coal mining activities in the West Banko Mine area, PT Bukit Asam Tbk. using a Shovel PC 3000 for overburden activities, while the transportation equipment is a DT Nissan CWB 45 for coal mining activities and the HD rigid truck Belaz 75135 for overburden activities
