At a number of ore deposits of the Far East and the Kola Peninsula dangerous for mining impacts, measurements of acoustic emission parameters have been carried out and new data have been obtained on the specific features of the manifestation of dangerous forms of rock pressure in various sections of the mine field. A method for measuring the local control device “Prognoz L” has been developed and additional criteria for the impact hazard of an array of rocks from a number of deposits developed by the underground method have been substantiated.
The principles of complexed geodynamic monitoring on the basis of long-term experience and research results of natural and man-made processes in the uranium deposits of the Streltsovsky ore province are proposed. The principles are to use simultaneously regular satellite, geodetical, seismical, geophysical, geological, and a number of other observations aimed at studying the upper part of the earth's crust. In the world’s mining practice, such large-scale integrated studies, where within the boundaries of one territory (a group of deposits or ore provinces) a similar set of observations aimed at monitoring geodynamic processes in the upper part of the earth's crust has not been found. The development of monitoring methods at the “Geodynamic polygon of the Streltsovsky ore field” and the additional placement of new multi-level monitoring systems will provide more information about the state of the rock mass in the upper part of the earth's crust, increase the reliability in prediction of dangerous geodynamic manifestations, identify their precursors and reduce the risk of man-made disasters. It is planned to create a common centre for processing and analysis of multiparameter data on geodynamic processes in the depth of the rock mass and local geomechanical processes near underground mine workings.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
