... the monitoring for the undermined rock mass. The mining method in a protective pillar the authors propose allows increasing reserves of the first mining stage by 76.9% and avoiding decrease in production volumes when mining operations terminate. Introduction The Oleniy Ruchey apatite-nepheline deposit...

... the Oleniy Ruchey deposit by underground methods in the near future. The underground mining operations will be restricted by protecting pillars because of nearby open-pits. High horizontal stresses and brittle rock have a significant influence on mining operations and indicate rockburst hazardous conditions...

... batters 10 m in height with 5 to 6 m wide berms giving an overall slope of 30 . Although now coal is mainly mined by open-pit mining operations, previously it was also extracted by under- ground operations. The low ratios of recuperation by the preceding underground mining allow the present surface mining...

It was recommended that for mining operations at the top part of the deposit to the depth of 6–8 m, the excavator should be located at least 3m from the slope edge. The other recommendations concerning the geotechnical instructions for mining operations were...
