Abstract
Coal mining in Indonesia has grown larger in the century. According to a great market demand to fulfill coal supply, the coal mining increases the coal production. Therefore, the coal mine area would be expanded to increase coal production and it needs study. Furthermore, one of the studies is bearing capacity study which is required to expand pit area. Purpose of this study is to determine the correlation of two bearing capacity methods and give the recommendation for appropriate mining equipment in field. Dynamic Cone Penetrometer (DCP) test and California Bearing Ratio (CBR) test are two methods, which are compared to obtain the best value of bearing capacity. Clay, coal, sandy clay materials are tested as sample materials. The of this study indicates that bearing capacity value from DCP test is higher than CBR test. An increment and degresion of bearing capacity value of DCP test are not followed by CBR test, it can be concluded that bearing capacity value of CBR test is used as basic reference to recommend the mining equipment. As the result, ground pressure of mining equipment would not be than 124 kPa, as recommendation. Keyword: bearing capacity, DCP test, CBR test, correlation
