Ore passes are simply vertical or inclined openings for transfer of broken ore to the haulage system. They may be raises in the ore or in the walls of the deposit or timbered openings through filled stopes and, as previously stated, usually terminate at the bottom in some form of loading chute. They must be steep enough to insure that the ore will run freely and usually are inclined at angles ...

May 24, 2014 The selection of an appropriate ore pass location is critical for the ore pass design process. Ore passes need to be designed to cut across ground levels and sub levels, in order to provide easy access to underground minerals. The intervals between ore passes should not exceed 500ft, or 150m. Ore pass inclination should be maintained between 45 and 90 , while ore pass length should
