  • Cave Tracker Mining3

    Block caving relies on fragmentation and forces of gravity to ‘cave’ an underground orebody to draw points, from where it is collected and taken away for processing. Monitoring the flow of the caved ore was only possible once markers, embedded in the orebody, exited at the draw points at the bottom.

  • Underground Mining Methods and Equipment

    Caving methods are defined as those associated w ith induced, controlled, massive caving of the ore body, the overlying rock, or both. Th e exploitation workings in caving methods are designed to collapse, with intentional caving of the ore and/or host rock. The three major caving methods are: • Longwall mining • Sublevel caving

  • Block Cave Underground Mine

    6 What and Why Block Caving? What : Block (gravity) caving is a bulk underground mining method, which allows large low-grade deposits to be mined underground. This method involves undermining the orebody to make it collapse under its own weight into a series of chambers from which the ore extracted.

It is a useful technique to extend the life of large deposits previously mined by

  • Inside block caving: the deep mining method of the future

    The role of block caving Although the caving mining system was initially used for shallow orebodies, it has recently been applied at depths of 2km underground. According to Suorineni, “caving heights have also increased drastically from about 200m to 500m”, creating so-called ‘super caves’.“There is insufficient experience caving in these environments,” he adds, which is a
