The present work suggests some activities which allow reducing the level of stressed-strained state within constructive
elements of a development system when recovering reserves of a deposit under interstage pillar by means of creating
protective zone with the help of the two panels in footwall and side wall. The actions are based on the principle of stresses
distribution within constructive elements of development by means of generating sharp angles in panels roof and bottom,
which concentrate maximum compressive stresses, therefore unloading bottom and future chambers roof mine working.
The given activities significantly simplify chamber reserves recovering inside the protective zone and allow stoping
practically any chamber development system with any number of fronts, and also give the possibility of controlling the
values of mining and carry out selective mining. The suggested solutions are examined by the example of Gayskoye
deposit.
Key words: protective zone; chamber development system; rock pressure control; stressed-strained state; stresses
concentration.
