Assessment of geodynamic and geomechanical conditions in the mining of ore bodies of near-ore bank reserves at the Koashva open-pit mine

Article preview

In connection with a gradual extraction of ore areas in a valley, with the aim of support of annual output of the Koashva open-pit mine, a necessity arises in involving in the mining of near-ore bank reserves, located in the north-west bench of open-pit mine. For uncovering and mining of near-ore bank reserves it is necessary to assess the geodynamic and geomechanical conditions for support of the safe mining operations. The article describes the solution of this problem by means of software product 3DEC of Itasca firm.

Modeling of geomechanical processes and their geophysical control in coal strata mining

Article preview

The paper presents the results of combination of geomechanical and geophyisical monitoring. The stress state of the minable coal seams is calculated according to the program FAULT3D with account of mining operations plan, specific seam occurrence and geological disturbances. The analysis of seismic events in the geodynamically hazardous zone has been made.
