V poslednie gody v rayonakh otrabotki poleznykh iskopaemykh uchastilis' sluchai proyavleniya gornykh udarov, vnezapnykh vybrosov, gornotektonicheskikh zemletryaseniy i drugikh geodinamicheskikh yavleniy. Eti protsessy porozhdayutsya v massivakh gornykh porod ne tol'ko deystviem bol'shikh tektonicheskikh napryazheniy, no i uvelicheniem glubiny otrabotki mestorozhdeniy, strukturnoy neodnorodnost'yu massiva i svoystvami slagayushchikh ego gornykh porod. Krupnye tekhnologicheskie vzryvy, primenyaemye dlya obrusheniya rudnykh blokov na zhelezorudnykh mestorozhdeniyakh, takzhe soprovozhdayutsya moshchnymi dinamicheskimi yavleniyami. Vse eto nanosit znachitel'nyy ekonomicheskiy ushcherb promyshlennym predpriyatiyam i grazhdanskim ob"ektam, a takzhe vedet k travmatizmu i chelovecheskim zhertvam. Poetomu osobuyu ostrotu priobrela problema monitoringa izmeneniya napryazhenno-deformirovannogo sostoyaniya massivov gornykh porod. Dlya isklyucheniya posledstviy geodinamicheskikh yavleniy neobkhodim nadezhnyy prognoz geologicheskikh usloviy vedeniya gornykh rabot.
