  • Sublevel caving QueensMineDesignWiki

    Sublevel caving is a relatively safe mining method since the operations take place in small areas at a time and are highly mechanized. The uniformly distributed nature of generally 5mx3.7m sublevel nature of drifts aids in the safety of this mining method. To increase the stability of drifts in competent rock is controlled by smooth blasting and shotcrete, whereas less competent rock is
