The main stages of artificial protective capping formation in the conditions of Yakovlevskoe iron ore deposit are discussed. The influence exerted by stoping sequence in the protective capping on the change in stress state of high-grade iron ore body under mining with the cut-and-fill method is analyzed. The features of limiting equilibrium zone formation around stopes are revealed and the values of ore crown pillar displacement are determined for different scenarios of mining. The analysis of the obtained results shows that the most adverse mining conditions arise in undermining of the protective capping arranged at the contact with backfill and lower-lying layer stopes. The developed numerical geomechanical model enables quantitative evaluation of influence of mining sequence on stability of stopes and validation of recommendations on safe mining.
