T he correlation physical properties of rocks between the geophysical log data with a laboratory tests performed on the strata of contain rocks coal in the concession PKP2B PT Borneo Indobara located in Kabupaten Tanah Bumbu, south kalimantan. In this study used method of associative who compares between grades wet density , dry density , saturated density , specific gravity of soil and porosity with a value of its density from a log long spaced density. The research indicated that the value of the equation a line on a graph correlation as follows: between wet density with the logs long spaced density is y = 0,1529x + 1,7312 to R² = 0,0258 or 2,58 % , between dry density with the logs long spaced density is y = 0,286x + 1,1416 to R² = 0,0386 or 3,86 % , between saturated density with the logs long spaced density is y = 0,1404x + 1,7787 to R² = 0,0227 or 2,27 % , between specific gravity of soil with the logs long spaced density is y = -0,1701x + 2,9592 to R² = 0,1139 or 11.39 %, between porosity with a log long spaced density is y = -0,1583x + 0,6638 to R² = 0,0833 or 8,33 %. This study concluded that between the value of the density of the geophysical well logging with the value of the parameters of the results of testing the physical properties laboratory there is no correlation , because of the influence of between logs long spaced density spaced a caliper with the logs , the data obtained from a drill hole to be equal with the data being tested in the laboratory , data and the conversion of a unit of CPS to gram/cc used to be exactly .
