Transverse longhole stoping - QueensMineDesignWiki

Transverse longhole stoping is a bulk mining method in which the long axis of the stope and access drifts are perpendicular to the strike of the orebody. Typically drawpoints are located in under-cut access drifts which extend from the footwall, and the free face is mined in a horizontal retreat from the hanging wall to the footwall.
