nalisis Penimbunan Overburden pada Pit 3 Timur Tambang Banko Barat di PT Bukit Asam Persero (Tbk) (original) (raw)

PT Bukit Asam (Persero) Tbk is one of the BUMN which is engaged in coal mining. This research was conducted in Pit 3 East West Banko operated by the contractor. The process of stripping overburden the difference in volume measurement survey overburden calculations progress ritation conveyance of overburden in one period, this can cause losses, therefore analysis overburden dumps.The study was conducted through a survey progress overburden, by measuring the elevation of each stage disposal area using Global Positioning System (GPS), then processed using Software Minescape to get volume of the preliminary draft and volume accumulation from February to October 2016 and then compared with the volume of every ritation to get a correction of cargo carrying means of each ritation. Testing of native soil specific gravity and material of disposal area to get a percentage compaction ofmaterial.The results showed the initial draft disposal volume amounted to 2,508,449.9 m 3
