Block Caving Mining Method: Transformation and Its Potency in Indonesia

The block caving mining method has become increasingly popular in the last two decades. Meanwhile, Indonesia several potential ore bodies which have not yet determined suitable methods. references to projects worldwide and potency of metal deposits were reviewed determine requirements for using transformed method. This can be applied on a blocky body with thickness 200–800 m, various rock mass strengths until 300 MPa, from low high (from 0.3% Cu more than 1.0% Cu), but uniform grade at depth 500 2200 m. technical specifications running mines been synthesized, including preparation methods, undercutting strategy, mine design, equipment monitoring. Considering successful practice project Grasberg Caving Complex as role model, Indonesian government should concentrate detailed exploration porphyry feasibility studies applying prospective bodies, i.e., Onto, Tambulilato, Tumpangpitu Randu Kuning. In addition, method, cost, operation, environment, policy social geology are important aspects worth noting.
