Abstract. In addition to providing benefits, marine mining activities can have a negative impact on the environment, causing various changes environment. One of efforts minimize resulting is Backfilling method, which direct closure ex-mining holes from ore reserves been taken in stages. this research, study reclamation planning and costs was carried out Sangau B.3 Block with an area 213.59 Ha. The technical includes studies manufacture installation FADs transplantation artificial coral...
Abstract. Limestone is an excavated material that can be used as a raw for cement. In the manufacture of cement there are three materials, namely limestone main material, then corrective iron sand and quartz additive gypsum. The compound CaO compound. formation limestone, value content has variations due to differences in facies process, so distribution not necessarily homogeneous. With requirement which 47%, it necessary have model describe geometry sediment levels at research site....

The importance of the need for water causes to become a major factor in sustainability existing mining activities. In addition, occurrence silt deposition main pond is separate problem which very likely cause silting pond. This study aims examine problems related and materials entering mine. Based on results research using calculation Gumbel distribution, through Mononobe equation rational formulas so that runoff discharge obtained where total enters washing 710.81 m3/day. Thus, order...
Abstract. In order to increase the production performance of Underground gold mine from 12,109 wmt/month 14,093 with progress excavation (horizontal slice) along 221.3 m/month 263.7 so that it is necessary efficiency and productivity production. As an approach use time Motion study method which learns measures measurement work movement all parameters involved in mining activities. Factors accounted for during this a way drilling transporting equipment ie using highest average value each...
Rancangan tahapan penambangan merupakan suatu bentuk ( mineable geometris ) yang menunjukan proses bukaan tambang dari awal hingga akhir tambang. Dengan cara membagi area menjadi bagian-bagian lebih sederhana. Sehingga dapat ditentukan kebutuhan tingkat produksi, jadwal produksi pemindahan lapisan tanah penutup dan penggalian batubara, umur fase. Didalam rancangan desain penambangan, optimasi dilakukan dengan menggunakan model blok. Optimasi berdasarkan rencana kebbutuhan batubara sebesar...
