Abstract

P Pada penanganan wetmuck mengharuskan dumping wetmuck ke LoadingPoint level truck haulage sebanyak 15 bucket LHD, namun kemampuanHydraulic Chute Loading Poin tidak mampu menangani beban dari Wet Muckdan juga konstruksi chute tidak di desain untuk menampung wet muck yang halusmengakibatkan kondisi actualnya chute bocor dari celah gate throat sehinggameluncur ke floor di level truck haulage yang resikonya operator dan trucktertimbun wetmuck sehingga seksi operation mengurangi jumlah bucket LHD dari15 menjadi 5 - 6 bucket sesuai dengan kapasaitas bucket truck. Penguranganjumlah bucket mempengaruhi produktivitas dan waktu menunggu loading pointkosong yang cukup lama. Maka perlu dicari cara untuk mengurangi waktumenunggu loading point kosong sehingga dapat meningkatkan produktivitasmucking LHD Minegem di level ekstraksi. Caranya dengan melakukan trial carabaru yaitu dumping langsung ke lantai LP. Dari hasil perbandingan produktivitasantara dumping tunggu dengan trial dumping langsung maka terjadi peningkatanProduktivitas panel yang meningkat dari 79.22 ton/jam menjadi 100.66 ton/jam.Semakin tinggi produktivitas Loader maka akan semakin tinggi juga produktivitaspanel

L Leave In handling the wetmuck requires dumping wetmuck to the Loading Pointlevel haulage truck of 15 LHD buckets, but the ability of the Hydraulic ChuteLoading Points is not able to handle the load from Wet Muck and also the chuteconstruction is not designed to accommodate a smooth wet muck resulting in theactual condition of the chute leaking from the gap gate throat so that it slides tothe floor at haulage truck level where the risk is the operator and truck are buriedwith wetmuck so that the operation section reduces the number of LHD bucketsfrom 15 to 5-6 buckets according to the capacity of the bucket truck. Reducing thenumber of buckets affects productivity and the waiting time for empty loadingpoints is long enough. So it is necessary to find a way to reduce the waiting timefor empty loading points so that it can increase the productivity of Minegem LHDmucking at the extraction level. The trick is to do a new trial method, which isdumping directly on the LP floor. From the results of productivity comparisonsbetween dumping waiting with direct dumping trials, an increase in panelproductivity increased from 79.22 tons / hour to 100.66 tons / hour. The higherthe productivity of the Loader, the higher the productivity of the panel
