Geo-deformation polygon and geomechanical research at the mine Magnesitovaya

Authors: Krinitsyn R.V.

The Satka deposit features rockburst hazard. The critical depth for launching prevention of dynamic phenomena of strata pressure in underground mining is from level +180m downward. The Geodynamics and Rock Pressure Laboratory at the Institute of Mining, Ural Branch, Russian Academy of Sciences has designed a geo-strain control facility enabling prompt tracking and early response to variations in the stress state of rock mass using the automated monitoring system. The automated monitoring system allows real-time tracking of deformation processes. The control facility is additionally equipped with large-spacing flexible-wire gauging stations, slot-measuring stations and photoelastic strain gaging stations. The geo-strain control facility makes it possible to respond promptly to the changes in the stress state of rock masses. The mine personnel apply appropriate ground control techniques which ensure safety of mining. As a result, the static and dynamic phenomena of strata pressure are minimized, and, consequently, safety of underground mine personnel is improved.

Keywords: Strain monitoring, rock mass control, photoelastic strain gaging, flexible wire method, borehole slotter, automated rock pressure control.
