| Summary: | Block Caving is a method of underground mining by underground method that utilize the force of gravity as a path-making or withdrawal of ore initiation in
extraction level, and ore handling facilities are designed to support the needs of the mined materials in drawpoint so that continuity can be maintained.
In application, Block Caving mining system requires special attention on the distribution of geological structures that may affect the development of caving in
the future. The major structures of the cave DOZ-GBT are Ertsberg 1 fault with the trend Northwest - Southeast, has a steep dipping, has the trend of N 2900 -3300 E, with the type of movement is sinistral strike-slip fault as PDZ (Principle Displacement Zone) in caving area of DOZ. Guru Fault with trend N 300 E, steep dipping,
trending NNE - SSW, and its movement is dextral strike-slip fault. And Concentrator Fault with N 550E with the direction of the trend NNE - SSW and the movement is dextral strike-slip fault. Guru Fault and Concentrator Fault are antitethic of fault zones in caving area DOZ. Those three faults are major structures that boundary of caving development. |
