Physical modeling of interchamber pillars fixity in Gubkin mine

Procedure of Korobkovsky iron-ore deposit new levels mining with the usage of physical modeling has been determined. Evaluation of interchamber pillars fixity in Gubkin mine and soil surface deformation in the process of lift mining and fractional interchamber pillars robbing on three levels has been carried out. After conducting geomechanical research the decision of foremost development and mining of bottom level reserve between –125 m / –250 m has been made.

Economic efficiency reducing ore losses in pillars of level-chamber method operational at the Korobkovsky of the iron-ore deposit

Technological solutions of ore loss reduction in interchamber pillars at bottom levels design of Gubkin mine are developed. For the purpose of justification of these offers has been carried out: physical (with the use of equivalent materials) and mathematical (finite element method) modeling. The research results and schedules of economic borders of use of new technologies are presented. The requirement for pilot work before industrial scale use is established.

Physical and mathematical modelling of level- chamber method operational parameters at the bottom level of Gubkin mine

Technological solutions of ore loss reduction in interchamber pillars at bottom levels design of Gubkin mine are developed. Research based on physical (with the use of equivalent materials) and mathematical (finite element method) modelling has been carried out. The requirement for pilot work before industrial scale use is  established.
