Putra Muba Coal is one of the subsidiaries under the MNC Group, operating in the coal mining sector with an IUP (Mining Business Permit) area covering 2,947 hectares. During its mining operations at the Pandu Pit, PT. Putra Muba Coal experienced a landslide incident on the highwall side. Therefore, a back-analysis using the deterministic method was conducted to determine the material property values that led to the slope failure in the mining area. The slope material consists of claystone and s...

Settlement of the ground floor of stockpile is caused by ground pressure of coal pile which is bigger than stockpile floor bearing capacity leads to bury under of some coal. So it is needed to do a study of optimum capacity by stockpile floor bearing capacity. Study of stockpile optimum capacity is started by calculating Californian Bearing Ratio (CBR) of stockpile subgrade using dynamic cone penetrometer in some location on each of the stockpile compartment. CBR value of stockpile subgrade conv...

PT. Pebana Adi Sarana targets monthly production operations of 20,000 tons/month while actual production is only around 15,000 tons/month, which means that the production target has not been achieved. The factors that cause the failure to achieve the production operation target can be due to ineffective equipment performance, Low equipment performance is one of the things that cause production not to be achieved, so it needs to be studied. The purpose of the study to be achieved is to analyze th...
