The research has been carried to determine coal quality at coal mine pit 2a South Block Lamin Project PT Mega Alam Sejahtera Berau East Borneo. The method that used in this research is well logging namely gamma ray log and density log to determine subsurface profile with 13 drilling point. From results of the analysis and interpretation of data obtained by the value of the average density is 1.63 g / cc, shale volume average of 0.2%, The average of ash conten 6:46%, average calorie of 5103.53 Kcal/kg, and the average of total moisture of 25%. With the scatterplot bivarian trendline method used to obtain the correlation of the two variables are variables X and Y, obtained strong-very strong correlation. From the analysis of the relationship with the density of the ash content has a correlation coefficient of R2 = 0520 or 52% (strong correlation), with total moisture density relationship has a correlation coefficient of R2 = 0828 or 43.31% (the correlation is very strong), the relationship with the calorie density has the correlation coefficient R2 = 0582, or 58.2% (strong correlation). While the relationship with the volume of shale ash content has a correlation coefficient of R2 = 0502, or 50.2% (strong correlation), shale volume relationship with calories has a correlation coefficient ata 0593 59.3% (strong correlation). Judging from the correlation of coal quality in the study area has a good quality. |
