Tinjauan Keserasian Alat Gali Muat Angkut untuk Mencapai Target Produksi 86.000 BCM/bulan pada Pit 3 PT. Leban Mutiara Hitam di Desa Leban Kecamatan Rantau Pandan Kabupaten Bungo Provinsi Jambi

PT. Leban Mutiara Hitam in early establishment named CV. Citra Perdana and has been established since 15th September 2006, in early February 2007 changed to PT. Leban Mutiara Hitam engaged in coal mining, which has reserves of coal sufficient potensial for development with total area of approximately 50 hectares located in the village of Rantau Pandan district Leban Muaro Bungo District in Jambi Province. In pit 3, PT. Leban Mutiara Hitam using the open pit system. In mining, PT Leban Mutiara Hitam combines work as an excavator and dump trucks unloading equipment and conveyances. Mining activities conducted include processes: excavation, loading, transportation and land use coal excavator. Production targets to be achieved largely determined by the productivity of this tool work. In pit 3, the production target of 86 000 BCM of overburden / month. In mining the role and availability of heavy equipment very important, because with the use of heavy equipment to facilitate mining operations. In the mining process, the planning needs of heavy equipment in mining very influential. If the utilization of heavy equipment is not in accordance with the needs on the ground, it can hamper the process of mining, such as queues conveyances which resulted in waiting times at loading tool. It can be anticipated based on the value of match factor, with the following provisions: -MF < 1 means there waiting time in unloading equipment while working a maximum of conveyance. -MF = 1 means the performance of conveyance and equipment load balanced. -MF > 1 means the waiting time occurred in transportation equipment while unloading equipment working optimally. At PT. Leban Mutiara Hitam problem that occurs is un balanced between the number of tool fits with the means of conveyance that resulted in the waiting time in unloading the tool, while the maximum conveyance work.
