Abstract
The safe parameters of temporary interchamber pillars have been determined for the chamber-and-pillar method with ore discharge on trenches in designing of underground mining of the Koashva apatite-nepheline deposit. The results of calculation of economical efficiency of comparable parameters are presented. It was substantiated that the economical efficiency of application of the chamber-and-pillar method up to the depth of 800 m is related to the increase of natural yielding of interchamber pillars.
