Evaluasi Geometri Jalan Alat Angkut dari Front II Menuju Crusher IIIA / IIIB Pada Penambangan Batu Kapur di IUP 206 Ha PT Semen Padang

PT. Semen Padang was established on March 18, 1910 under the name NV Nederlandsch Indische Portland Cement (NV NIPCM), located in Indarung, about 15 km to the East of Padang City, administratively included in Kecamatan Lubuk Kilangan, Padang City, West Sumatra Province with higher altitude Less
200 mdpl. PT. Semen Padang performs limestone mining activities using the quarry open quarry method.
Road access is an important factor in achieving the volume of rocks being moved. A good road will support the fulfillment of desired production targets and production per dump truck will also be good. As it is known that HD785-7 Komatsu is a conveyance that has a major contribution to total mining
production in PT. Semen Padang.
On the mean haul road measurement of road width of 19 m, road width at bend 19,14 m, radius of 10.71 superelevation equal to 16,8%, grade at corner equal to 13%, and cross slope The cross slope on front area II is not clear. After a theoretical evaluation, the minimum width of the straight path for two lanes of 25 m, minimum width for twin bends of 29 m, superelevation 4.7%, grade <8%, and cross slope of 26-44 cm. The geometry of the mine road is made for the smooth process of transporting minerals, the geometry of the mine must be in accordance with the means of conveyance used and must be made in accordance with predetermined standards to support the smoothness of mining activities.
