Innovative Approach to Opening Strength Management, Cost Efficiency

Abstract
The article examines theoretical, laboratory and mine methods in order to determine the opening strength depending on concentration of normal stresses in the massive. It describes impact of relief bags on reduction of stress concentration in the rocks around the workings. It shows efficiency of rocks relief from rock pressure by formation of the bags using the blast energy. It noted the impact of the wall length and the depth of its location on stressed-deformed state (SDS) of the rocks inclosing the working, as the most part of them decompose at a depth of over 800 m. The relief using bags enables to increase the wall length, reduce the cost of 1 ton of end product and improve the innovative level of the enterprise.

Keywords
Mine working, Relief bags, Stress concentration, Stressed-deformed state.

Results of Geometrical Sounding of Vegetal Ecosystems
On Rock Dumps at Beryozovsky Open-pit Mine

Abstract
The article presents the results of space sounding of surface vegetal ecosystem on rock dumps at coal Beryozovsky open-pit mine. It brings to light the dynamics of formation and growth of vegetal ecosystems on external and internal rock dumps piled in the various periods of construction and development of the Beryozovsky brown coalfield strip mine construction (1970-1980), further development of reserves by experimental-industrial strip mine Beryozovsky (1975-1990), reserves development using transport-dumped flow and cyclic techniques (1990-2014.).

Keywords
Coal strip mining, Rock dumps, Space sounding, Surface vegetal ecosystems, Soil recultivation.
