  • Definition of block caving Mindat

    The term 'block caving' probably originated in the porphyry copper mines, where the area to be mined was divided into rectangular blocks that were mined in a checkerboard sequence with all the ore in a block being removed before an adjacent block was mined. This sequence of mining is no longer widely used. Today most mines use a panel systemA new mining company uses block caving to exploit ,A new mining company uses block caving to exploit copper from an underground. mine. In order to ensure the stability of the new development drives, they would like to find out in-situ-stresses in underground using destressing and destressing-restressing techniques.

However, in combined surface and underground mining, the breakthrough of an underground caving under an open pit may result in subsidence at the bottom of the pit. This can pose a serious threat for the stability of the pit and the safety of the mining.
