Abstract
Mining coal that is mined by PT. Diva Kencana Borneo based business
license exploitation of coal in the administrative district located in the Village of
Muhur, District of Siluq Ngurai West Kutai Regency of East Kalimantan
Province.
The purpose of this study is to obtain the magnitude of the mixing ratio
of coal in accordance with consumer demand and plan activities to meet the coal
blending coal quality that consumers want.
Research methods used in the preparation of this study is the method of
blending coal direct and indirect methods. Direct method is done by conducting
direct observation in the field, while the indirect method is done by studying
literature from the library or from the archives and documents of the company.
In this coal blending study comes from different Pit Sangsang who was
in the stockpile are set based on the quality of which SP 01 are from seam A1, A3,
A5, A6, A7, A8, B1 (mine out) with a high sulfur content, SP 02 comes of seam
A2, A4 (mine out) with low sulfur content. SP 03 from seam A2, A4 (product),
SP 04 from seam A1, A3, A5, A6, A7, A8, B1 (products) and that is in radial
stacker is distinguished by the SP LS sulfur content (low sulfur) and SP HS (high
sulfur).
The results of coal blending calculations of actual conditions in the
stockpile between SP 01 and SP 04 is required for coal from 5000.97 tons
(19.25%) and SP 04 at 20990.04 tons (81.75%) and the quality of the coal
blending TM content = 18.96%, Ash = 2.6%, TS = 1.53%, and CVadb= 6,194 kcal
/ kg. The results of coal blending calculations of actual conditions in the stockpile
between SP 02 and SP 03 coal required from SP 02 at 15107.91 tonnes (37.77%)
and from SP 03 at 24892.09 tonnes (62.23%) and the quality of the coal blending
TM content = 19.71%, Ash = 2.86%, TS = 0.32%, and CVadb= 6,205 kcal / kg.
Optimum blending results for PT. Diva Kencana Borneo namely coal
blending between stockpile high sulfur and low sulfur coal for high sulfur
stockpile of 37,000 tons of and low sulfur stockpile of 29,000 tons or percentage
of stockpile high sulfur coal at 56.20% and stockpile low sulfur at 43.80% will
produce coal with TM content = 19.29%, Ash = 2.71%, TS = 1%, CV adb= 6,201
kcal / kg.
