PT. Surya Global Makmur is one of the mining companies in Indonesia, which is engaged in the mining and sale of coal commodities. Coal mining activities at PT Surya Global Makmur are designed in monthly mining sequences. This study aims to determine the achievement of production based on mining plans and areas where mining discrepancies occur, the factors that cause them, as well as the consequences and efforts that can be made. The achievement of PT Surya Global Makmur production in February 2023 based on the mining plan was 50% of 100,000 tons, namely 50.016,59 tons of coal, and 70% of 584.276 BCM, namely 409.129,8 BCM for overburden. So that the overcut results for coal and overburden are 5.363,85 tons and 151.356,06 BCM respectively, there are areas of undercut coal and overburden of 55.347,26 tons and 326.429,26 BCM respectively. The cause of the failure based on the mine plan design, is the effective working time of the overburden loading digger is less than planned, and the actual productivity of the overburden loading digging equipment does not reach the planned target, and lack of supervision. Efforts that can be made are adding loss time indicators in monthly reports as an effort to increase EWH, increase supervision of mining directions, operator performance and time discipline, and suitability of mining plan stakes.
