ABSTRACT
The problem of decrease in risk of technogenic catastrophes at large-scale mining operations is very actual problem for the Far East region where a number of the deposits are burst-hazard. Methods and technical means for the research of a geomechanical condition of rock massif of and results of their application on the burst-hazard underground mines of the East of Russia are considered in the article. Application of a complex of the numerical and instrumental methods is effective for the assessment of burst hazard and geodynamic risk. Measuring complex includes seismo-acoustic and straining devices. Multi-channel geoacoustic (“Prognoz ADS”) and microseismic (“Prognoz S”) systems of monitoring, a portable device “Prognoz L”, a laser deformograph and other measuring tools are included in the measuring complex. Regularities of change of geophysical fields reflecting processes of redistribution of tension in the massif and preparation of the hazard geodynamic phenomena are determined.
