Provision of Stability of Development Mining at Yakovlevo Iron Ore Deposit

摘要

This article discusses solution of urgent problem of stability provision of development mining at Yakovlevo iron ore deposit (Russia) by means of selection and determination of types and rational parameters of support on the basis of theoretical and experimental studies described here. In order to characterize the state if static stability of unsupported mining we propose the stress criterion of mining elements (roof and sidewalls), on the basis of which the categories are highlighted characterizing possible stability states of mining rocks and forms of rock pressure manifestation. Depending on the value of stability criterion of mining outcropping the recommendations have been developed on selection of types and parameters of support of development mining in ore body.
