摘要：
The authors solve the problem on stress-strain state of adjacent rocks of ore passes arranged in the face area under caved ore and the ore passes arranged both lengthwise the stope and in the stope face area (the face ore drawing scheme and the stope-through drawing, respectively) by using the finite element method. The article describes stress distribution in higher stress zones and in distressed areas depending on ore discharge preparation techniques at depths down to 1.5 km.
