MINING OBJECTS: CONCEPT OF MULTILEVEL MONITORING OF THEIR GEOHYDROMECHANICAL STATE
Anatoly Kalashnik Leading Researcher of Geoflyuidomechanikal Laboratory, Dr (Eng.), Mining institute KSC RAS, Apatity, Russia, e-mail:kalashnik@goi.kolasc.net.ru
Abstract. Conceptual approaches to forming of multilevel monitoring of a geohydromechanical status of mining objects which basis the principle of integration of the cross-disciplinary researches including land and GPS geodetic, geophysical and hydrological measurements and also subsurface, land, air and satellite georadar shooting is are stated. Approaches are based on carrying out regime observations at the different levels: remote, air, land, subsurface and also computer simulation, and synchronous processing of results with use of information technologies «BIG DATA» and «CLOUD SERVICE». Natural multilevel researches make a basis of monitoring as a result of which data retrieved about a geohydromechanical status of mining objects in the automated mode supplement databases of decision making support system. Multilevel approach is used also in computer simulation: 2D and 3D models of mining objects as hierarchically enclosed structures are created, with their multilarge-scale research. The concept of multilevel complex monitoring of a geohydromechanical status of mining objects is approved at the main mining enterprises of the Kola Peninsula. Keywords: mining objects, monitoring, multilevel researches, integration, industrial and environmental safety.

U. Analiyeva teacher of Scientific and educational complex KazNIITU Uralsk, Kazakhstan, e-mail: azhara_1980@mail.ru
Abstract. The article is devoted to the development of the concept of building an automated system for monitoring and controlling emergencies and determining its structure and location. Examples of monitoring objects are given and the relevance of the development and implementation of such systems is shown. The proposed concept implies a multi-level hierarchical structure of the monitoring system with an open architecture, at the lower level of which are multifunctional sensors of physical quantities installed on controlled objects or territories. It is proved that, to a greater extent, it is the sensors that determine the reliability and information content of the entire monitoring system. With reference to the mudflow hazard monitoring system, the range of sensors used has been determined. The issues of raising awareness and efficiency of monitoring and warning are considered. It is shown that the proposed concept can be implemented and function properly only with the availability of modern software and hardware. Using the example of a 4-tier monitoring system, the tasks solved at its various levels are described in detail. Keywords: environment, monitoring, control, sensors, disaster, man-made, mudflow, pollution, interface.
