PERENCANAAN PENAMBANGAN BATUBARA BERSAMA DI BATAS IUP OPERASI PRODUKSI (SHARING WALL) DI PT MERAPI ENERGY COAL

---

The loss of coal reserves in mining concession boundaries is commonly caused by conventional pit designs based on administrative limits, which create boundary pillars and result in stranded coal. This study aims to evaluate the technical and economic feasibility of implementing a sharing wall mining concept as a coal resource conservation strategy in the boundary area of PT Merapi Energy Coal’s mining concession in Lahat Regency, South Sumatra Province. The research method includes geological continuity and structural analysis to assess technical feasibility, comparative pit design evaluation between double wall and sharing wall scenarios using identical geotechnical parameters, and an economic assessment based on a discounted cash flow approach. The results indicate that the coal seams in the study area exhibit good lateral continuity and are not affected by major geological structures, confirming their technical suitability for sharing wall implementation. The application of the sharing wall design increases coal recovery from 21.9% to 60.3%, raises mineable reserves from 5.7 million tons to 17.5 million tons, and extends the mine life from 6 years to 15 years. From an economic perspective, the sharing wall scenario significantly improves project value, with Net Present Value (NPV) increasing from IDR 496 billion to IDR 982 billion, while government revenue rises from IDR 1.2 trillion to IDR 4 trillion. Overall, the company’s cumulative profit increases by up to 197%, driven by higher production levels, improved resource utilization efficiency, and extended mine life. These findings demonstrate that the sharing wall approach is an effective and value-adding conservation strategy in coal mine planning at concession boundaries, supporting the implementation of good mining practice and enhancing national economic benefits.
