Kaltim Prima Coal merupakan salah perusahaan yang bergerak dalam bidang pertambangan batubara. Kegiatan penambangan batubara dilakukan oleh Divisi Mining Operations yang terdiri atas beberapa departemen yang memiliki tugas masing-masing. Pengupasan top soil dilakukan oleh Departemen Mining Services, khususnya seksi Rehabilitasi. Kegiatan ini menggunakan alat gali-muat jenis Excavator Backhoe tipe Komatsu PC 750/800 SE dan alat angkut jenis Articulated Dump Truck tipe Volvo A35E/F dan CAT 740. Pencapaian target produksi pengupasan top soil tahun 2016 telah tercapai, namun terdapat isu delay wait on trucks yang besar dalam berlangsungnya kegiatan pengupasan top soil. Hasil pengamatan menunjukkan 4 dari 5 area loading point memiliki match factor dibawah 0.85. Pengoptimalan match factor secara perencanaan (planning) diperlukan agar penggunaan alat mekanis menjadi optimal. Pengoptimalan waktu edar alat mekanis, usage alat mekanis, serta pendekatan perencanaan waktu edar alat mekanis ...

Safe ground condition is the most important thing on production stage related to safety of employees and property in underground. Rockfall is one of fatal risks for employees who work in underground. It happens when ground deformation getting worse. The deformation monitoring is a needed to observe the behavior of rock mass, early detection of hazards, and evaluate current ground support system. The damaged ground in DOZ Mine on production stage is mainly caused by stress around the pillar. It has related to the lifetime of DOZ Mine approximate 3 years left. No mucking activity causes rock wegdes above the pillar and total load for pillars strength. There is maximum stress and strain rock of pillar which it will be broken ground when the stress and strain pass through the maximum value. The type categories of damaged are slight damage, moderate damage, heavy...
