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

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.

Geomechanical substantiation of projects of ore deposits mining

The paper presents the monitoring system for better geodynamic safety in mining of mineral deposits. The suggested system of geodynamic monitoring allows us to evaluate the stress state of ore massif for the planned variant of mining and to give recommendations on the safe deposit mining. Based on the analysis of the modeling data, consideration was given to one of the variants of geomechanical substantiation of the project of ore deposit mining.

Particular formation of higher rock pressure zones with intensive mining of contiguous seams at coal mines of the «Suek-Kuzbass» CO

The problem of mining the suites of contiguous coal seams is considered. The sequential manner of seams mining essentially has influence on change of rock and gas pressure. The results of calculation and construction of borders of zones of higher rock pressure are presented. The analysis of conditions of hazardous zones formation is given.

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

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.
