Measurements of parameters of acoustic emission were carried out on a number of burst hazard mineral deposits of the Far East and Transbaikalia. New data on features of phenomena of hazard forms of rock pressure on various sites of the mine are obtained. The technique of carrying out of measurements by “Prognoz L” local monitoring device is developed. Criteria of burst-hazard properties of the rock massif on a number of the mineral deposits, being developed by underground mining, were substantiated.

Rock Burst Prediction

The relevance of research. When developing underground mining, there is a risk of dynamic phenomenon of high rock pressure - rock burst. The local instrumental forecast of shock hazard by acoustic emission with the GS-01 device allows you to quickly identify high-tension zones during underground mining. The Research aim: generalization of the accumulated data of instrumental measurements of acoustic emission parameters throughout the Sokolovskaya mine; zoning of rock burst hazard in the deposit; use of zoning of rock burst hazard results for mining planning in terms of changing the principles and regulations for designing traces of mine workings in potentially impact hazardous areas; improving the methodology of instrumental forecasting of shock hazard by the acoustic emission method. Methods of research: analysis of the accumulated data of instrumental measurements of acoustic emission parameters during mining; theoretical studies (identifying patterns of changes in acoustic emission taking into account the influence of mining, the configuration of the excavation, etc.); measurement in situ (measurement of acoustic emission parameters when changing parameters underground working). Results of research: implementation of preventive measures (the so-called “relaxation” of the rock) to reduce the rock burst risk in hazard zones during mining; implementation of research results in normative and technical documentation.

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 paper investigates cross-cultural differences across Russian regions using the methodology of G. Hofstede. First, it discusses the most common approaches in measuring culture and the application of the Hofstede methodology in subnational studies. It identifies the critical issues in measuring culture at the regional level and suggests several strategies to address them. Secondly, the paper introduces subregional data on individualism and uncertainty avoidance using a survey of students across 27 Russian universities. The data allow to establish geographical patterns of individualism in Russia. It is demonstrated that collectivism is most prevalent in the Volga region, while individualism characteristic becomes stronger towards the Far East. The findings are robust to the inclusion of various controls and different specifications of the regression model. Finally, the paper provides a discussion about the potential of applying the sociocultural approach in economics.
