Essay

The thesis is dedicated to safe and economic maintenance of development workings based on methods of stress state management of metal-frame supports and host massif. Basic idea of the work is usage of detected phenomena of dislocating fractured zones formation close to the moving exposed surface (longwallstope) for scientific substantiation and development of new constructions of metal-frame supports providing safety and effectiveness of development workings support in complex mining-geological conditions. New approach and requirements for strain-force parameters of supports is substantiated; new representation of laws of strain processes flow within developed massif is given; character and interaction mechanism of support and developed massif is established; new approach of workings reliability management is substantiated by way of preliminary reserving and optimization of support durability reserve with expected influence of moving stress-strain zones. It would allow to substantiate and develop new constructions of metal-frame, lock connections and mine special profile that provide significant increase of development workings stability and decrease of costs for their maintenance.
